Forward-looking statements include statements with respect to the Company's beliefs, plans, objectives, goals, expectations, anticipations, assumptions, estimates, and intentions about future performance, and involve known and unknown risks, uncertainties and other factors any of which may be impacted by the COVID-19 pandemic and related effects on the U.S. economy, which may be beyond the Company's control, and which may cause the actual results, performance or achievements of Seacoast Banking Corporation of Florida (“Seacoast” or the “Company”) or its wholly-owned banking subsidiary, Seacoast National Bank (“Seacoast Bank”) to be materially different from those set forth in the forward-looking statements. All statements other than statements of historical fact could be forward-looking statements. You can identify these forward- looking statements through the use of words such as “may,” “will,” “anticipate,” “assume,” “should,” “support,” “indicate,” “would,” “believe,” “contemplate,” “expect,” “estimate,” “continue,” “further,” “plan,” “point to,” “project,” “could,” “intend,” “target” or other similar words and expressions of the future. These forward-looking statements may not be realized due to a variety of factors, including, without limitation: • • • • • • • • • • • • • • • • the effects of future economic and market conditions, including seasonality; the adverse effects of COVID-19 (economic and otherwise) on the Company and its customers, counterparties, employees, and third-party service providers, and the adverse impacts to our business, financial position, results of operations, and prospects; government or regulatory responses to the COVID-19 pandemic; governmental monetary and fiscal policies, including interest rate policies of the Board of Governors of the Federal Reserve (“Federal Reserve”), as well as legislative, tax and regulatory changes; changes in accounting policies, rules and practices, including the impact of the adoption of the current expected credit losses (“CECL”) methodology; our participation in the Paycheck Protection Program (“PPP”); the risks of changes in interest rates on the level and composition of deposits, loan demand, liquidity and the values of loan collateral, securities, and interest rate sensitive assets and liabilities; interest rate risks, sensitivities and the shape of the yield curve; uncertainty related to the impact of LIBOR calculations on securities, loans and debt; changes in borrower credit risks and payment behaviors, including as a result of the financial impact of COVID-19; changes in retail distribution strategies, customer preferences and behavior; changes in the availability and cost of credit and capital in the financial markets; changes in the prices, values and sales volumes of residential and commercial real estate; the Company's ability to comply with any regulatory requirements; the effects of problems encountered by other financial institutions that adversely affect Seacoast or the banking industry; Seacoast's concentration in commercial real estate loans and in real estate collateral in the state of Florida; 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; 3 • • • • • • • • • • • • • • • • statutory and regulatory dividend restrictions; increases in regulatory capital requirements for banking organizations generally; the risks of mergers, acquisitions and divestitures, including Seacoast's ability to continue to identify acquisition targets and successfully acquire and integrate desirable financial institutions; 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 as a result of employees working remotely; inability of Seacoast's risk management framework to manage risks associated with the 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 mobile-based platform that is critical to the Company's business growth strategy; the effects of war or other conflicts, acts of terrorism, natural disasters, health emergencies, epidemics or pandemics, or other catastrophic events that may affect general economic conditions; unexpected outcomes of, and the costs associated with, existing or new litigation involving the Company, including as a result of the Company's participation in the PPP; Seacoast's ability to maintain adequate internal controls over financial reporting; potential claims, damages, penalties, fines and reputational damage resulting from pending or future litigation, regulatory proceedings and enforcement actions; the risks that deferred tax assets could be reduced if estimates of future taxable income from operations and tax planning strategies are less than currently estimated and sales of capital stock could trigger a reduction in the amount of net operating loss carryforwards that the Company may be able to utilize for income tax purposes; 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 operating in the Company's market areas and elsewhere, including institutions operating regionally, nationally and internationally, together with such competitors offering banking products and services by mail, telephone, computer and the Internet; the failure of assumptions underlying the establishment of reserves for possible credit losses; and other factors and risks described under “Risk Factors” herein and in any of the Company's subsequent reports filed with the SEC and available on its website at www.sec.gov. Given the many unknowns and risks being heavily weighted to the downside, our forward-looking statements are subject to the risk that economic conditions will be substantially different in the future. If efforts to contain COVID-19 are delayed and restrictions on movement last into the second half of 2021 and beyond, the recession could be longer and more severe. Ineffective fiscal stimulus, or an extended delay in implementing it, are also major downside risks. The deeper the recession is, and the longer it lasts, the more it will damage consumer fundamentals and sentiment. This could both prolong the recession, and/or make any recovery weaker. Similarly, the recession could damage business fundamentals. COVID-19 and its related economic impact, including the impact of measures to manage it, have had and are likely to continue to have an adverse effect, possibly materially, on Seacoast's business and financial performance by adversely affecting, possibly materially, the demand and profitability of the Company's products and services, the valuation of assets and its ability to meet the needs of its customers. All written or oral forward-looking statements that are made or are attributable to Seacoast are expressly qualified in their entirety by this cautionary notice. The Company assumes no obligation to update, revise or correct any forward-looking statements that are made from time to time, either as a result of future developments, new information or otherwise, except as may be required by law. 4 Item 1. Business General Part I Seacoast Banking Corporation of Florida (“Seacoast” or the “Company”) is a financial holding company, incorporated in Florida in 1983, and registered under the Bank Holding Company Act of 1956, as amended (the “BHC Act”). Its principal subsidiary is Seacoast National Bank, a wholly-owned national banking association (“Seacoast Bank”), which commenced its operations in 1933. As of December 31, 2020, the Company’s legal structure also included seven trusts formed for the purpose of issuing trust preferred securities. Seacoast Bank has three wholly-owned subsidiaries. Through one of these subsidiaries, Seacoast Bank has a controlling interest in a real estate investment trust (“REIT”). Unrelated investors own a noncontrolling interest in the preferred stock of the REIT. Seacoast Bank also provides brokerage and annuity services. Seacoast Bank personnel managing the sale of these services are dual employees with LPL Financial, the company through which Seacoast Bank presently conducts brokerage and annuity services. In 2018, the Company established Seacoast Insurance Services, Inc., providing customers with access to a range of insurance products. As of December 31, 2020, Seacoast had total consolidated assets of $8.3 billion, total deposits of $6.9 billion, total consolidated liabilities, including deposits, of $7.2 billion and consolidated shareholders’ equity of $1.1 billion. Operations are discussed in more detail under “Item 7. Management’s Discussion and Analysis of Consolidated Financial Condition and Results of Operations.” Seacoast has grown to be one of the largest community banks headquartered in Florida. This growth has been achieved through a balanced strategy consisting of organic growth and acquisitions in the state's most attractive markets. The Company provides integrated financial services including commercial and retail banking, wealth management and mortgage services to customers through advanced banking solutions and Seacoast Bank's network of 51 traditional branches and stand-alone commercial banking centers. Seacoast operates primarily in Florida, with concentrations in the state's fastest growing markets, each with unique characteristics and opportunities that support the Company's strategy of organic growth and attractive acquisitions. Seacoast Bank customers can also access their account information and perform transactions online, through mobile applications, or through Seacoast Bank's telephone customer support center, which offers extended hours. These options, combined with a traditional branch footprint, meet a broad range of customer needs. Available Information The Company's principal offices are located at 815 Colorado Avenue, Stuart, Florida 34994, and the telephone number at that address is (772) 287-4000. The Company and Seacoast Bank maintain Internet websites at www.seacoastbanking.com and www.seacoastbank.com, respectively. The information on these websites is not part of this report and neither of these websites nor the information appearing on these websites is included or incorporated in this report. Seacoast makes available, free of charge on its corporate website, its Annual Report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and any amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act, as soon as reasonably practicable after such material is electronically filed with or furnished to the SEC. Expansion of Market and Competition Seacoast has in recent years sought to complement organic growth with the acquisition of financial institutions that support the Company's strategy and expand its ability to serve customers in Florida's key markets. Since 2014, Seacoast has acquired ten institutions that have enhanced the Company's presence in the strongest and fastest growing MSAs in Florida, including two acquisitions in 2020; First Bank of the Palm Beaches (“FBPB”) in March 2020 and Fourth Street Banking Company (“Fourth Street”) and Fourth Street’s wholly owned subsidiary bank, Freedom Bank, in August 2020. FBPB and Freedom Bank operated two branches in the Palm Beach market and two branches in the St. Petersburg market, respectively. The Company expects these acquisitions to enhance its presence in those markets, expand its customer base, leverage operating costs through economies of scale, and positively affect the Company’s operating results. 5 In 2020, the Company added business bankers across key markets, invested in technology to improve banker productivity in both office and remote environments, and enhanced customer self-service. Seacoast has continued to expand digital offerings to provide an improved customer experience and lower the cost to serve, as well as to meet the ever-changing needs of its customer base during the COVID-19 pandemic, which has influenced how customers interact with Seacoast and accelerated the shift to digital banking for many customer segments. Seacoast operates in a highly competitive market. Competitors range in both size and geographic footprint. Seacoast operates throughout Florida from the southeast, including Fort Lauderdale, Boca Raton and Palm Beach, north along the east coast to the Daytona area, into Orlando and Central Florida and the adjacent Tampa market, and west to Okeechobee and surrounding counties. Seacoast Bank's competition includes not only other banks of comparable or larger size in the same markets, but also various other nonbank financial institutions, including savings and loan associations, credit unions, mortgage companies, personal and commercial financial companies, peer to peer lending businesses, investment brokerage and financial advisory firms and mutual fund companies. Seacoast Bank competes for deposits, commercial, fiduciary and investment services and various types of loans and other financial services. Seacoast Bank also competes for interest-bearing funds with a number of other financial intermediaries, including brokerage and insurance firms, as well as investment alternatives, including mutual funds, governmental and corporate bonds, and other securities. Continued consolidation and rapid technological changes within the financial services industry will likely change the nature and intensity of competition, but should also create opportunities for the Company to demonstrate and leverage its competitive advantages. Competitors include not only financial institutions based in Florida, but also a number of large out-of-state and foreign banks, bank holding companies and other financial institutions that have an established market presence in Florida or that offer internet-based products. Many of the Company's competitors are engaged in local, regional, national and international operations and have greater assets, personnel and other resources. Some of these competitors are subject to less regulation and/ or more favorable tax treatment. Many of these institutions have greater resources, broader geographic markets and higher lending limits, and may offer services that the Company does not offer. In addition, these institutions may be able to better afford and make broader use of media advertising, support services, and electronic and other technology. To offset these potential competitive disadvantages, the Company depends on its reputation for superior service, ability to make credit and other business decisions quickly, and the delivery of an integrated distribution of traditional branches and bankers, with digital technology. Human Capital As of December 31, 2020, the Company and its subsidiaries employed 965 full time-equivalent employees. Any discussion of the past year must be framed within the context of the COVID-19 pandemic and its impact on our employees and communities. Our priority in addressing the pandemic thus far has been to carefully adjust our physical operations to protect the health and welfare of our associates and customers while providing continuous access to banking services. We shifted branch operations to remain open by drive-thru or lobby appointment only for part of 2020, implemented enhanced cleaning and protection protocols, and our operational teams continue to work remotely or in staggered shifts. Recognizing the challenges that the pandemic has brought to all of our personal and professional lives, and the related impact on our team, we have implemented various programs to support our associates’ well-being. These include bonuses for retail and lending associates, who have kept critical functions operating at full capacity, and an employee assistance program that provides short-term counseling and other wellness resources. Seacoast invests in its employees for the long term. To empower associates to achieve their potential and enable their success, we provide a variety of professional development programs, opportunities, and resources. Among these is the Seacoast Manager Excellence Program, which was recently recognized by American Banker when they named Seacoast one of 2020’s Best Banks to Work For. This program supports associates as they progress from individual contributor to manager, focusing on creating purpose, driving results, developing talent, and leading change. Seacoast believes that a culture of inclusion and diversity enhances its entire workforce. Seacoast strives to make inclusion a hallmark of our culture, engaging associates in our Associate Resource Group (“ARG”) programs led by and comprised of associates who have diverse backgrounds and experiences, and who share a common interest in professional development, improving corporate culture, and building stronger communities. Currently, Seacoast ARGs include Black Associates and Allies Network (“BAAN”), LGBTQ+, Veterans, and Women Mean Business. Each is sponsored and supported by senior leaders across the enterprise. The Company also commits to having a diverse talent pipeline by partnering with its business units in their efforts to recruit diverse talent across all leadership and skill areas. The Company considers employee relations to be favorable, and has no collective bargaining agreements with any employees. We believe our ability to attract and retain employees is a key to our success. Accordingly, we implemented, in July 2018, a $15 per hour minimum pay rate company-wide. We continue to strive to offer competitive salaries and employee benefits 6 including, among others, paid vacation time, medical, dental and vision insurance benefits, 401(k) plan with company match, tuition assistance, and an employee stock purchase plan. Supervision and Regulation The Company is extensively regulated under federal and state law. The following is a brief summary that does not purport to be a complete description of all regulations that affect the Company or all aspects of those regulations. This discussion is qualified in its entirety by reference to the particular statutory and regulatory provisions described below and is not intended to be an exhaustive description of the statutes or regulations applicable to the Company’s and Seacoast Bank’s business. In addition, proposals to change the laws and regulations governing the banking industry are frequently raised at both the state and federal levels. The likelihood and timing of any changes in these laws and regulations, and the impact such changes may have on the Company and Seacoast Bank, are difficult to predict. In addition, bank regulatory agencies may issue enforcement actions, policy statements, interpretive letters and similar written guidance applicable to the Company or Seacoast Bank. Changes in applicable laws, regulations or regulatory guidance, or their interpretation by regulatory agencies or courts may have a material adverse effect on the Company and Seacoast Bank’s business, operations, and earnings. Supervision and regulation of banks, their holding companies and affiliates is intended primarily for the protection of depositors and customers, the Deposit Insurance Fund (“DIF”) of the Federal Deposit Insurance Corporation (“FDIC”), and the U.S. banking and financial system rather than holders of the Company's capital stock. Regulation of the Company: The Company is registered as a bank holding company with the Federal Reserve under the Bank Holding Company Act of 1956, as amended (the “BHC Act”) and has elected to be a financial holding company. As such, the Company is subject to comprehensive supervision and regulation by the Federal Reserve and to its regulatory reporting requirements. Federal law subjects financial holding companies, such as Seacoast, to particular restrictions on the types of activities in which they may engage, and to a range of supervisory requirements and activities, including regulatory enforcement actions for violations of laws and regulations. Violations of laws and regulations, or other unsafe and unsound practices, may result in regulatory agencies imposing fines or penalties, cease and desist orders, or taking other enforcement actions. Under certain circumstances, these agencies may enforce these remedies directly against officers, directors, employees and other parties participating in the affairs of a bank or bank holding company. If we become subject to and are unable to comply with the terms of any future regulatory actions or directives, supervisory agreements, or orders, then we could become subject to additional, heightened supervisory actions and orders, possibly including consent orders, prompt corrective action restrictions and/or other regulatory actions, including prohibitions on the payment of dividends on our common and preferred stock. If our regulators were to take such additional supervisory actions, then we could, among other things, become subject to significant restrictions on our ability to develop any new business, as well as restrictions on our existing business, and we could be required to raise additional capital, dispose of certain assets and liabilities within a prescribed period of time, or both. The terms of any such supervisory action could have a material negative effect on our business, reputation, operating flexibility, financial condition, and the value of our common stock. Activity Limitations: As a financial holding company, Seacoast is permitted to engage directly or indirectly in a broader range of activities than those permitted for a bank holding company. Bank holding companies are generally restricted to engaging in the business of banking, managing or controlling banks and certain other activities determined by the Federal Reserve to be closely related to banking. Financial holding companies may also engage in activities that are considered to be financial in nature, as well as those incidental or, if so determined by the Federal Reserve, complementary to financial activities. The Company and Seacoast Bank must each remain “well-capitalized” and “well-managed” and Seacoast Bank must receive a Community Reinvestment Act (“CRA”) rating of at least “Satisfactory” at its most recent examination in order for the Company to maintain its status as a financial holding company. In addition, the Federal Reserve has the power to order a financial holding company or its subsidiaries to terminate any nonbanking activity or terminate its ownership or control of any nonbank subsidiary, when it has reasonable cause to believe that continuation of such activity or such ownership or control constitutes a serious risk to the financial safety, soundness, or stability of any bank subsidiary of that financial holding company. As further described below, each of the Company and Seacoast Bank is well-capitalized as of December 31, 2020, and Seacoast Bank has a rating of “Outstanding” in its most recent CRA evaluation. Source of Strength Obligations: As a bank holding company, we are required to act as a source of financial and managerial strength to Seacoast Bank and to maintain resources adequate to support it. The term “source of financial strength” means the ability to provide financial assistance in the event of financial distress. As regulator of Seacoast Bank, the Office of the Comptroller of the Currency (the “OCC”) may require reports from the Company to assess its ability to serve as a source of strength and to enforce compliance with the source of strength requirements and require the Company to provide financial assistance to Seacoast Bank in the event of financial distress. 7 Acquisitions: The BHC Act permits acquisitions of banks by bank holding companies, such that Seacoast and any other bank holding company, whether located in Florida or elsewhere, may acquire a bank located in any other state, subject to certain deposit-percentages, age of bank charter requirements, and other restrictions. The BHC Act requires that a bank holding company obtain the prior approval of the Federal Reserve before (i) acquiring direct or indirect ownership or control of more than 5% of the voting shares of any additional bank or bank holding company, (ii) taking any action that causes an additional bank or bank holding company to become a subsidiary of the bank holding company, or (iii) merging or consolidating with any other bank holding company. The Federal Reserve may not approve any such transaction that would result in a monopoly or would be in furtherance of any combination or conspiracy to monopolize or attempt to monopolize the business of banking in any section of the United States, or the effect of which may be substantially to lessen competition or to tend to create a monopoly in any section of the country, or that in any other manner would be in restraint of trade, unless the anticompetitive effects of the proposed transaction are clearly outweighed in the public interest by the probable effect of the transaction meeting the convenience and needs of the community to be served. The Federal Reserve is also required to consider: (1) the financial and managerial resources of the companies involved, including pro forma capital ratios; (2) the risk to the stability of the United States banking or financial system; (3) the convenience and needs of the communities to be served, including performance under the CRA; and (4) the effectiveness of the companies in combating money laundering. Change in Control: Federal law restricts the amount of voting stock of a bank holding company or a bank that a person may acquire without the prior approval of banking regulators. Under the Change in Bank Control Act and the regulations thereunder, a person or group must give advance notice to the Federal Reserve before acquiring control of any bank holding company, such as Seacoast, and the OCC before acquiring control of any national bank, such as Seacoast Bank. Upon receipt of such notice, the bank regulatory agencies may approve or disapprove the acquisition. The Change in Bank Control Act creates a rebuttable presumption of control if a person or group acquires the power to vote 10% or more of the Company's outstanding common stock. The overall effect of such laws is to make it more difficult to acquire a bank holding company and a bank by tender offer or similar means than it might be to acquire control of another type of corporation. Consequently, shareholders of the Company may be less likely to benefit from the rapid increases in stock prices that may result from tender offers or similar efforts to acquire control of other companies. Investors should be aware of these requirements when acquiring shares of the Company's stock. Governance and Financial Reporting Obligations: Seacoast is required to comply with various corporate governance and financial reporting requirements under the Sarbanes-Oxley Act of 2002, as well as rules and regulations adopted by the Securities and Exchange Commission (the “SEC”), the Public Company Accounting Oversight Board (the “PCAOB”), and the NASDAQ Global Select Market (“NASDAQ”) stock exchange. In particular, the Company is required to include management and independent registered public accounting firm reports on internal controls as part of its Annual Report on Form 10-K in order to comply with Section 404 of the Sarbanes-Oxley Act. The Company has evaluated its controls, including compliance with the SEC rules on internal controls, and has and expects to continue to spend significant amounts of time and money on compliance with these rules. Failure to comply with these internal control rules may materially adversely affect the Company's reputation, its ability to obtain the necessary certifications to financial statements, and the value of the Company's securities. The assessments of the Company's financial reporting controls as of December 31, 2020 are included in this report under “Item 9A. Controls and Procedures.” Corporate Governance: The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) addressed many investor protection, corporate governance, and executive compensation matters that affect most U.S. publicly traded companies. The Dodd-Frank Act: (1) granted shareholders of U.S. publicly traded companies an advisory vote on executive compensation; (2) enhanced independence requirements for Compensation Committee members; and (3) required companies listed on national securities exchanges to adopt incentive-based compensation claw-back policies for executive officers. Incentive Compensation: The Dodd-Frank Act required the banking agencies and the SEC to establish joint rules or guidelines for financial institutions with more than $1 billion in assets, which prohibit incentive compensation arrangements that the agencies determine to encourage inappropriate risks by the institution. The federal banking agencies issued proposed rules in 2011 and issued guidance on sound incentive compensation policies. In 2016, the federal banking agencies also proposed rules that would, depending upon the assets of the institution, directly regulate incentive compensation arrangements and would require enhanced oversight and recordkeeping. As of December 31, 2020, these rules have not been implemented. The Company and Seacoast Bank have undertaken efforts to ensure that their incentive compensation plans do not encourage inappropriate risks, consistent with three key principles: that incentive compensation arrangements should appropriately balance risk and financial rewards, be compatible with effective controls and risk management, and be supported by strong corporate governance. Shareholder Say-On-Pay Votes: The Dodd-Frank Act requires public companies to provide shareholders with an advisory vote on executive compensation (known as say-on-pay votes), the frequency of a say-on-pay vote, and the golden parachutes 8 available to executives in connection with change-in-control transactions. Public companies must give shareholders the opportunity to vote on say-on-pay proposals at least every three years and the opportunity to vote on the frequency of say-on- pay votes at least every six years, indicating whether the say-on-pay vote should be held annually, biennially, or triennially. The Company has annually included in the proxy statement a separate advisory vote on the compensation paid to executives. The say-on-pay, the say-on-parachute and the say-on-frequency votes are advisory and explicitly nonbinding and cannot override a decision of the Company's board of directors. Volcker Rule: Section 13 of the BHC Act, commonly referred to as the “Volcker Rule,” generally prohibits banking organizations with greater than $10 billion in assets from (i) engaging in certain proprietary trading, and (ii) acquiring or retaining an ownership interest in or sponsoring a “covered fund,” all subject to certain exceptions. The Volcker Rule also specifies certain limited activities in which bank holding companies and their subsidiaries may continue to engage and requires banking organizations to implement compliance programs. In 2020, amendments to the proprietary trading and covered funds regulations issued by the federal banking agencies, the SEC, and the CFTC took effect, simplifying compliance and providing additional exclusions and exemptions. The Company and the Bank were not subject to the Volcker Rule in 2020, but may become so in the future. Other Regulatory Matters: The Company and its subsidiaries are subject to oversight by the SEC, the Financial Industry Regulatory Authority, (“FINRA”), the PCAOB, the NASDAQ stock exchange and various state securities regulators. The Company and its subsidiaries have from time to time received requests for information from regulatory authorities in various states, including state attorneys general, securities regulators and other regulatory authorities, concerning business practices. Such requests are considered incidental to the normal conduct of business. Capital Requirements: The Company and Seacoast Bank are required under federal law to maintain certain minimum capital levels based on ratios of capital to total assets and capital to risk-weighted assets. The required capital ratios are minimums, and the Federal Reserve and OCC may determine that a banking organization, based on its size, complexity or risk profile, must maintain a higher level of capital in order to operate in a safe and sound manner. Risks such as concentration of credit risks and the risk arising from non-traditional activities, as well as the institution’s exposure to a decline in the economic value of its capital due to changes in interest rates, and an institution’s ability to manage those risks are important factors that are to be taken into account in assessing an institution’s overall capital adequacy. The following is a brief description of the relevant provisions of these capital rules and their potential impact on the Company's and Seacoast Bank's capital levels. The Company and Seacoast Bank are subject to the following risk-based capital ratios: a common equity Tier 1 (“CET1”) risk- based capital ratio, a Tier 1 risk-based capital ratio, which includes CET1 and additional Tier 1 capital, and a total risk-based capital ratio, which includes Tier 1 and Tier 2 capital. CET1 is primarily comprised of the sum of common stock instruments and related surplus net of treasury stock, plus retained earnings, and certain qualifying minority interests, less certain adjustments and deductions, including with respect to goodwill, intangible assets, mortgage servicing assets and deferred tax assets subject to temporary timing differences. Additional Tier 1 capital is primarily comprised of noncumulative perpetual preferred stock, tier 1 minority interests and grandfathered trust preferred securities. Tier 2 capital consists of instruments disqualified from Tier 1 capital, including qualifying subordinated debt, other preferred stock and certain hybrid capital instruments, and a limited amount of loan loss reserves up to a maximum of 1.25% of risk-weighted assets, subject to certain eligibility criteria. The capital rules also define the risk-weights assigned to assets and off-balance sheet items to determine the risk-weighted asset components of the risk-based capital rules, including, for example, “high volatility” commercial real estate, past due assets, structured securities and equity holdings. The leverage capital ratio, which serves as a minimum capital standard, is the ratio of Tier 1 capital to quarterly average total consolidated assets net of goodwill, certain other intangible assets, and certain required deduction items. The required minimum leverage ratio for all banks and bank holding companies is 4%. In addition, effective January 1, 2019, the capital rules require a capital conservation buffer of 2.5% above each of the minimum risk-based capital ratio requirements (CET1, Tier 1 and total risk-based capital), which is designed to absorb losses during periods of economic stress. These buffer requirements must be met for a bank or bank holding company to be able to pay dividends, engage in share buybacks or make discretionary bonus payments to executive management without restriction. The Federal Deposit Insurance Corporation Improvement Act of 1991 (“FDICIA”), among other things, requires the federal bank regulatory agencies to take “prompt corrective action” regarding depository institutions that do not meet minimum capital requirements. FDICIA establishes five regulatory capital tiers: “well capitalized”, “adequately capitalized”, “undercapitalized”, “significantly undercapitalized”, and “critically undercapitalized”. A depository institution’s capital tier will depend upon how its capital levels compare to various relevant capital measures and certain other factors, as established by regulation. FDICIA imposes progressively more restrictive restraints on operations, management and capital distributions, depending on the category in which an institution is classified. FDICIA generally prohibits a depository institution from making any capital 9 distribution (including payment of a dividend) or paying any management fee to its holding company if the depository institution would thereafter be undercapitalized. To be well-capitalized, Seacoast Bank must maintain at least the following capital ratios: • • • • 10.0% Total capital to risk-weighted assets 8.0% Tier 1 capital to risk-weighted asset 6.5% CET1 to risk-weighted assets; and 5.0% leverage ratio. The Federal Reserve has not yet revised the well-capitalized standard for bank holding companies to reflect the higher capital requirements imposed under the current capital rules. For purposes of the Federal Reserve’s Regulation Y, including determining whether a bank holding company meets the requirements to be a financial holding company, bank holding companies, such as the Company, must maintain a Tier 1 risk-based capital ratio of 6.0% or greater and a total risk-based capital ratio of 10.0% or greater to be well-capitalized. If the Federal Reserve were to apply the same or a similar well- capitalized standard to bank holding companies as that applicable to Seacoast Bank, the Company’s capital ratios as of December 31, 2020 would exceed such revised well-capitalized standard. Also, the Federal Reserve may require bank holding companies, including the Company, to maintain capital ratios substantially in excess of mandated minimum levels, depending upon general economic conditions and a bank holding company’s particular condition, risk profile and growth plans. Failure to be well-capitalized or to meet minimum capital requirements could result in certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have an adverse material effect on the operations or financial condition of the Company or Seacoast Bank. Failure to meet minimum capital requirements could also result in restrictions on the Company’s or Seacoast Bank’s ability to pay dividends or otherwise distribute capital or to receive regulatory approval of applications or other restrictions on growth. In 2020, the Company’s and Seacoast Bank’s regulatory capital ratios were above the well-capitalized standards and met capital conservation buffer as of December 31, 2020. Based on current estimates, we believe that the Company and Seacoast Bank will continue to exceed all applicable well-capitalized regulatory capital requirements and the capital conservation buffer in 2021. As of December 31, 2020 the consolidated capital ratios of Seacoast and Seacoast Bank were as follows: Total Risk-Based Capital Ratio Tier 1 Capital Ratio Common Equity Tier 1 Capital Ratio (CET1) Leverage Ratio 1For subsidiary bank only Seacoast (Consolidated) 18.51% 17.46 16.17 11.92 Seacoast Bank 17.21% 16.15 16.15 11.03 Minimum to be Well-Capitalized1 10.00% 8.00 6.50 5.00 Payment of Dividends: The Company is a legal entity separate and distinct from Seacoast Bank and its other subsidiaries. The Company's primary source of cash, other than securities offerings, is dividends from Seacoast Bank. The prior approval of the OCC is required if the total of all dividends declared by a national bank (such as Seacoast Bank) in any calendar year will exceed the sum of such bank’s net profits for that year and its retained net profits for the preceding two calendar years, less any required transfers to surplus. Federal law also prohibits any national bank from paying dividends that would be greater than such bank’s undivided profits after deducting statutory bad debts in excess of such bank’s allowance for possible loan losses. In addition, the Company and Seacoast Bank are subject to various general regulatory policies and requirements relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. The appropriate federal bank regulatory authority may prohibit the payment of dividends where it has determined that the payment of dividends would be an unsafe or unsound practice. The OCC and the Federal Reserve have indicated that paying dividends that deplete a bank’s capital base to an inadequate level would be an unsound and unsafe banking practice. The OCC and the Federal Reserve have each indicated that depository institutions and their holding companies should generally pay dividends only out of current operating earnings. Under a Federal Reserve policy adopted in 2009, the board of directors of a bank holding company must consider different factors to ensure that its dividend level is prudent relative to maintaining a strong financial position, and is not based on overly optimistic earnings scenarios, such as potential events that could affect its ability to pay, while still maintaining a strong 10 financial position. As a general matter, the Federal Reserve has indicated that the board of directors of a bank holding company should consult with the Federal Reserve and eliminate, defer or significantly reduce the bank holding company’s dividends if: • • • its net income available to shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends; its prospective rate of earnings retention is not consistent with its capital needs and overall current and prospective financial condition; or it will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios. The Company has traditionally relied upon dividends from Seacoast Bank and securities offerings to provide funds to pay the Company’s expenses and to service the Company’s debt. During the year ended December 31, 2020, Seacoast Bank distributed $20.2 million to the Company. During the year ended December 31, 2019, Seacoast Bank distributed $18.1 million to the Company. Prior approval by the OCC is required if the total of all dividends declared by a national bank in any calendar year exceeds the bank’s profits for that year combined with its retained net profits for the preceding two calendar years. Under this restriction Seacoast Bank is eligible to distribute dividends up to $213.4 million to the Company, without prior OCC approval, as of December 31, 2020. No dividends on the Company's common stock were declared or paid in 2020, 2019, and 2018. Regulation of the Bank: As a national bank, Seacoast Bank is subject to comprehensive supervision and regulation by the OCC and is subject to its regulatory reporting requirements. The deposits of Seacoast Bank are insured by the FDIC up to the applicable limits, and, accordingly, the bank is also subject to certain FDIC regulations and the FDIC has backup examination authority and certain enforcement powers over Seacoast Bank. Seacoast Bank also is subject to certain Federal Reserve regulations. As the Company and the Bank each had less than $10 billion in consolidated assets in 2020, they are not subject to the routine supervision of the CFPB, but this may change in the future as the Company and the Bank grow. In addition, as discussed in more detail below, Seacoast Bank and any of the Company's other subsidiaries that offer consumer financial products and services are subject to regulation and potential supervision by the Consumer Financial Protection Bureau (“CFPB”). Authority to supervise and examine the Company and Seacoast Bank for compliance with federal consumer laws remains largely with the Federal Reserve and the OCC, respectively. However, the CFPB may participate in examinations on a “sampling basis” and may refer potential enforcement actions against such institutions to their primary regulators. The CFPB also may participate in examinations of the Company's other direct or indirect subsidiaries that offer consumer financial products or services. In addition, the Dodd-Frank Act permits states to adopt consumer protection laws and regulations that are stricter than those regulations promulgated by the CFPB, and state attorneys general are permitted to enforce certain federal consumer financial protection law. Broadly, regulations applicable to Seacoast Bank include limitations on loans to a single borrower and to its directors, officers and employees; restrictions on the opening and closing of branch offices; the maintenance of required capital ratios; the granting of credit under equal and fair conditions; the disclosure of the costs and terms of such credit; requirements to maintain reserves against deposits and loans; limitations on the types of investments that may be made by Seacoast Bank; and requirements governing risk management practices. Seacoast Bank is permitted under federal law to open a branch on a de novo basis across state lines where the laws of that state would permit a bank chartered by that state to open a de novo branch. Transactions with Affiliates and Insiders: Seacoast Bank is subject to restrictions on extensions of credit and certain other transactions between Seacoast Bank and the Company or any nonbank affiliate. Generally, these covered transactions with either the Company or any affiliate are limited to 10% of Seacoast Bank’s capital and surplus, and all such transactions between Seacoast Bank and the Company and all of its nonbank affiliates combined are limited to 20% of Seacoast Bank’s capital and surplus. Loans and other extensions of credit from Seacoast Bank to the Company or any affiliate generally are required to be secured by eligible collateral in specified amounts. In addition, any transaction between Seacoast Bank and the Company or any affiliate are required to be on an arm’s length basis. Federal banking laws also place similar restrictions on certain extensions of credit by insured banks, such as Seacoast Bank, to their directors, executive officers and principal shareholders. Reserves: Federal Reserve rules require depository institutions, such as Seacoast Bank, to maintain reserves against their transaction accounts, primarily interest bearing and non-interest bearing checking accounts. Effective March 26, 2020, reserve requirement ratios were reduced to zero percent. These reserve requirements are subject to annual adjustment by the Federal Reserve. 11 FDIC Insurance Assessments and Depositor Preference: Seacoast Bank’s deposits are insured by the FDIC’s DIF up to the limits under applicable law, which currently are set at $250,000 per depositor, per insured bank, for each account ownership category. Seacoast Bank is subject to FDIC assessments for its deposit insurance. The FDIC calculates quarterly deposit insurance assessments based on an institution’s average total consolidated assets less its average tangible equity, and applies one of four risk categories determined by reference to its capital levels, supervisory ratings, and certain other factors. The assessment rate schedule can change from time to time, at the discretion of the FDIC, subject to certain limits. Deposit insurance may be terminated by the FDIC upon a finding that the institution has engaged in unsafe and unsound practices, is in an unsafe or unsound condition to continue operations, or has violated any applicable law, regulation, rule, order or condition imposed by a bank’s federal regulatory agency. In addition, the Federal Deposit Insurance Act provides that, in the event of the liquidation or other resolution of an insured depository institution, the claims of depositors of the institution, including the claims of the FDIC on behalf of insured depositors, and certain claims for administrative expenses of the FDIC as a receiver, will have priority over other general unsecured claims against the institution, including those of the parent bank holding company. Standards for Safety and Soundness: The Federal Deposit Insurance Act requires the federal bank regulatory agencies to prescribe, by regulation or guideline, operational and managerial standards for all insured depository institutions relating to: (1) internal controls; (2) information systems and audit systems; (3) loan documentation; (4) credit underwriting; (5) interest rate risk exposure; and (6) asset quality. The federal banking agencies have adopted regulations and Interagency Guidelines Establishing Standards for Safety and Soundness to implement these required standards. These guidelines set forth the safety and soundness standards used to identify and address problems at insured depository institutions before capital becomes impaired. Under the regulations, if a regulator determines that a bank fails to meet any standards prescribed by the guidelines, the regulator may require the bank to submit an acceptable plan to achieve compliance, consistent with deadlines for the submission and review of such safety and soundness compliance plans. Anti-Money Laundering: A continued focus of governmental policy relating to financial institutions in recent years has been combating money laundering and terrorist financing. The Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (the “USA PATRIOT Act”) broadened the application of anti-money laundering regulations to apply to additional types of financial institutions such as broker-dealers, investment advisors and insurance companies, and strengthened the ability of the U.S. Government to help prevent, detect and prosecute international money laundering and the financing of terrorism. The principal provisions of Title III of the USA PATRIOT Act require that regulated financial institutions, including state member banks: (i) establish an anti-money laundering program that includes training and audit components; (ii) comply with regulations regarding the verification of the identity of any person seeking to open an account; (iii) take additional required precautions with non-U.S. owned accounts; and (iv) perform certain verification and certification of money laundering risk for their foreign correspondent banking relationships. Failure of a financial institution to comply with the USA PATRIOT Act’s requirements could have serious legal and reputational consequences for the institution. Seacoast National Bank has augmented its systems and procedures to meet the requirements of these regulations and will continue to revise and update its policies, procedures and controls to reflect changes required by law. FinCEN has adopted rules that require financial institutions to obtain beneficial ownership information with respect to legal entities with which such institutions conduct business, subject to certain exclusions and exemptions. Bank regulators are focusing their examinations on anti-money laundering compliance, and we continue to monitor and augment, where necessary, our anti-money laundering compliance In addition, FinCEN issued rules that became effective on May 11, 2018, that require, subject to certain exclusions and exemptions, covered financial institutions to identify and verify the identity of beneficial owners of legal entity customers. Banking regulators will consider compliance with the Act’s money laundering provisions in acting upon acquisition and merger proposals. Bank regulators routinely examine institutions for compliance with these obligations and have been active in imposing cease and desist and other regulatory orders and money penalty sanctions against institutions found to be violating these obligations. Sanctions for violations of the Act can be imposed in an amount equal to twice the sum involved in the violating transaction, up to $1 million. On January 1, 2021, Congress passed federal legislation that made sweeping changes to federal anti-money laundering laws, including changes that will be implemented in 2021 and subsequent years. Economic Sanctions: The Office of Foreign Assets Control (“OFAC”) is responsible for helping to ensure that U.S. entities do not engage in transactions with certain prohibited parties, as defined by various Executive Orders and acts of Congress. OFAC publishes, and routinely updates, lists of names of persons and organizations suspected of aiding, harboring or engaging in terrorist acts, including the Specially Designated Nationals and Blocked Persons List. If the Company finds a name on any transaction, account or wire transfer that is on an OFAC list, it must undertake certain specified activities, which could include blocking or freezing the account or transaction requested, and it must notify the appropriate authorities. 12 Concentrations in Lending: In 2006, the federal bank regulatory agencies released guidance on “Concentrations in Commercial Real Estate Lending” (the “Guidance”) and advised financial institutions of the risks posed by commercial real estate (“CRE”) lending concentrations. The Guidance requires that appropriate processes be in place to identify, monitor and control risks associated with real estate lending concentrations. Higher allowances for loan losses and capital levels may also be required. The Guidance is triggered when CRE loan concentrations exceed either: • • Total reported loans for construction, land development, and other land of 100% or more of a bank’s total risk based capital; or Total reported loans secured by multifamily and nonfarm nonresidential properties and loans for construction, land development, and other land of 300% or more of a bank’s total risk based capital. The Guidance also applies when a bank has a sharp increase in CRE loans or has significant concentrations of CRE secured by a particular property type. Seacoast Bank has exposures to loans secured by commercial real estate due to the nature of its markets and the loan needs of both our retail and commercial customers. Seacoast Bank believes that its long term experience in CRE lending, underwriting policies, internal controls, and other policies currently in place, as well as its loan and credit monitoring and administration procedures, are generally appropriate to managing our concentrations as required under the Guidance. At December 31, 2020, Seacoast Bank had outstanding $157.4 million in commercial construction and residential land development loans and $87.7 million in residential construction loans to individuals, which represents approximately 26% of total risk-based capital at December 31, 2020, well below the Guidance’s threshold. At December 31, 2020, the total CRE exposure for Seacoast Bank represents approximately 169% of total risk based capital, also below the Guidance’s threshold. On a consolidated basis, construction and land development and commercial real estate loans represent 24% and 157%, respectively, of total consolidated risk-based capital. Debit Interchange Fees: Interchange fees, or “swipe” fees, are fees that merchants pay to card companies and card-issuing banks such as Seacoast Bank for processing electronic payment transactions on their behalf. The “Durbin Amendment” in the Dodd-Frank Act provides limits on the amount of debit card interchange that may be received or charged by the debit card issuer, for insured depository institutions with $10 billion or more in assets (inclusive of its affiliates) as of the end of the calendar year. Subject to certain exemptions and potential adjustments, the Durbin Amendment limits debit card interchange received or charged by the issuer to $0.21 plus 5 basis points multiplied by the value of the transaction. Upon crossing the $10 billion asset threshold in a calendar year, the rules require compliance with these limits by no later than July 1 of the succeeding year. Seacoast Bank did not exceed the $10 billion asset threshold in 2020. Community Reinvestment Act: Seacoast Bank is subject to the provisions of the Community Reinvestment Act (“CRA”), which imposes a continuing and affirmative obligation, consistent with safe and sound operation, to help meet the credit needs of entire communities where the bank accepts deposits, including low- and moderate-income neighborhoods. The OCC’s assessment of Seacoast Bank’s CRA record is made available to the public. Following the enactment of the Gramm-Leach- Bliley Act (“GLBA”), CRA agreements with private parties must be disclosed and annual CRA reports must be made to a bank’s primary federal regulator. A bank holding company is not permitted to become or remain a financial holding company and no new activities authorized under GLBA may be commenced by a holding company or by a bank financial subsidiary if any of its bank subsidiaries receive less than a “satisfactory” CRA rating in its latest CRA examination. Federal CRA regulations require, among other things, that evidence of discrimination against applicants on a prohibited basis, and illegal or abusive lending practices be considered in the CRA evaluation. In June 2020, the OCC issued final rules to modernize the CRA, but those rules have not yet been fully implemented and may change. Seacoast Bank has a rating of “Outstanding” in its most recent CRA evaluation. Privacy and Data Security: The GLBA generally prohibits disclosure of consumer information to non-affiliated third parties unless the consumer has been given the opportunity to object and has not objected to such disclosure. Financial institutions are further required to disclose their privacy policies to customers annually. Financial institutions, however, will be required to comply with state law if it is more protective of consumer privacy than the GLBA. The GLBA also directs federal regulators, including the FDIC and the OCC, to prescribe standards for the security of consumer information. Seacoast Bank is subject to such standards, as well as standards for notifying customers in the event of a security breach. Seacoast Bank is similarly required to have an information security program to safeguard the confidentiality and security of customer information and to ensure proper disposal. Customers must be notified when unauthorized disclosure involves sensitive customer information that may be misused. On December 18, 2020, federal banking agencies proposed a new rule that would require banks to notify their regulators within 36 hours of a “computer-security incident” that rises to the level of a “notification incident”. Consumer Regulation: Activities of Seacoast Bank are subject to a variety of statutes and regulations designed to protect consumers. These laws and regulations include, among numerous other things, provisions that: 13 • • • • • • limit the interest and other charges collected or contracted for by Seacoast Bank, including new rules respecting the terms of credit cards and of debit card overdrafts; govern Seacoast Bank’s disclosures of credit terms to consumer borrowers; require Seacoast Bank to provide information to enable the public and public officials to determine whether it is fulfilling its obligation to help meet the housing needs of the community it serves; prohibit Seacoast Bank from discriminating on the basis of race, creed or other prohibited factors when it makes decisions to extend credit; govern the manner in which Seacoast Bank may collect consumer debts; and prohibit unfair, deceptive or abusive acts or practices in the provision of consumer financial products and services. Mortgage Regulation: The CFPB adopted a rule that implements the ability-to-repay and qualified mortgage provisions of the Dodd-Frank Act (the “ATR/QM rule”), which requires lenders to consider, among other things, income, employment status, assets, payment amounts, and credit history before approving a mortgage, and provides a compliance “safe harbor” for lenders that issue certain “qualified mortgages.” The ATR/QM rule defines a “qualified mortgage” to have certain specified characteristics, and generally prohibits loans with negative amortization, interest-only payments, balloon payments, or terms exceeding 30 years from being qualified mortgages. The rule also establishes general underwriting criteria for qualified mortgages, including that monthly payments be calculated based on the highest payment that will apply in the first five years of the loan and that the borrower have a total debt-to-income ratio that is less than or equal to 43%. While “qualified mortgages” will generally be afforded safe harbor status, a rebuttable presumption of compliance with the ability-to-repay requirements will attach to “qualified mortgages” that are “higher priced mortgages” (which are generally subprime loans). In addition, the securitizer of asset-backed securities must retain not less than five percent of the credit risk of the assets collateralizing the asset-backed securities, unless subject to an exemption for asset-backed securities that are collateralized exclusively by residential mortgages that qualify as “qualified residential mortgages.” The CFPB has also issued rules to implement requirements of the Dodd-Frank Act pertaining to mortgage loan origination (including with respect to loan originator compensation and loan originator qualifications) as well as integrated mortgage disclosure rules. In addition, the CFPB has issued rules that require servicers to comply with certain standards and practices with regard to: error correction; information disclosure; force-placement of insurance; information management policies and procedures; requiring information about mortgage loss mitigation options be provided to delinquent borrowers; providing delinquent borrowers access to servicer personnel with continuity of contact about the borrower’s mortgage loan account; and evaluating borrowers’ applications for available loss mitigation options. These rules also address initial rate adjustment notices for adjustable-rate mortgages (ARMs), periodic statements for residential mortgage loans, and prompt crediting of mortgage payments and response to requests for payoff amounts. In 2020, the CARES Act granted certain forbearance rights and protection against foreclosure to borrowers with a “federally backed mortgage loan,” including certain first or subordinate lien loans designed principally for the occupancy of one to four families. These consumer protections continue during the COVID-19 pandemic emergency. Non-Discrimination Policies: Seacoast Bank is also subject to, among other things, the provisions of the Equal Credit Opportunity Act (the “ECOA”) and the Fair Housing Act (the “FHA”), both of which prohibit discrimination based on race or color, religion, national origin, sex, and familial status in any aspect of a consumer or commercial credit or residential real estate transaction. The Department of Justice (the “DOJ”), and the federal bank regulatory agencies have issued an Interagency Policy Statement on Discrimination in Lending that provides guidance to financial institutions in determining whether discrimination exists, how the agencies will respond to lending discrimination, and what steps lenders might take to prevent discriminatory lending practices. The DOJ has increased its efforts to prosecute what it regards as violations of the ECOA and FHA. Item 1A. Risk Factors In addition to the other information set forth in this report, you should consider the factors described below, as well as the risk factors and uncertainties discussed in our other public filings with the SEC under the caption “Risk Factors” in evaluating us and our business and making or continuing an investment in our stock. The material risks and uncertainties that management believes affect us are described below. The risks contained in this Form 10-K are not the only risks facing the Company. Additional risks and uncertainties not currently known to us, or that we currently deem to be immaterial, also may materially 14 adversely affect our business, financial condition or future results. The trading price of our securities could decline due to the materialization of any of these risks, and our shareholders may lose all or part of their investment. This Form 10-K also contains forward-looking statements that may not be realized as a result of certain factors, including, but not limited to, the risks described herein and in our other public filings with the SEC. Please refer to the section in this Form 10-K entitled “Special Cautionary Notice Regarding Forward-Looking Statements” for additional information regarding forward-looking statements. COVID-19 Pandemic-Related Risks The COVID-19 pandemic has and will continue to adversely impact our business and financial results, and the ultimate impact will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic and actions taken by governmental authorities in response to the pandemic. The COVID-19 pandemic is and is likely to continue creating extensive disruptions to the global economy and to the lives of individuals throughout the world. Governments, businesses, and the public are taking unprecedented actions to contain the spread of the COVID-19 pandemic and to mitigate its effects, including quarantines, travel bans, shelter-in-place orders, closures of businesses and schools, fiscal stimulus, and legislation designed to deliver monetary aid and other relief. While the scope, duration, and full effects of the COVID-19 pandemic are rapidly evolving and not fully known, the COVID-19 pandemic and related efforts to contain it have disrupted economic activity, adversely affected the functioning of financial markets, impacted interest rates, increased economic and market uncertainty, and disrupted trade and supply chains. If these effects continue for a prolonged period or result in sustained economic stress, recession or depression, they could have a material adverse impact on us in a number of ways related to credit, collateral, customer demand, funding, operations, interest rate risk, and human capital, as described in more detail below. Credit Risk. Our risks of timely loan repayment and the value of collateral supporting the loans are affected by the strength of our borrowers' businesses. Concern about the spread of the COVID-19 pandemic has caused and is likely to continue to cause business shutdowns, limitations on commercial activity and financial transactions, labor shortages, supply chain interruptions, increased unemployment and commercial property vacancies, reduced profitability and ability for property owners to make mortgage payments, and overall economic and financial market instability, all of which may cause our customers to be unable to make scheduled loan payments. If the effects of the COVID-19 pandemic result in widespread and sustained repayment shortfalls on loans in our portfolio, we could incur significant delinquencies, foreclosures and credit losses, particularly if the available collateral is insufficient to cover our exposure. The future effects of the COVID-19 pandemic on economic activity could negatively affect the collateral values associated with our existing loans, the ability to liquidate the real estate collateral securing our residential and commercial real estate loans, our ability to maintain loan origination volume and to obtain additional financing, the future demand for or profitability of our lending and services, and the financial condition and credit risk of our customers. Further, in the event of delinquencies, regulatory changes and policies designed to protect borrowers may slow or prevent us from making our business decisions or may result in a delay in our taking certain remediation actions, such as foreclosure. In an effort to support our communities during the COVID-19 pandemic, we participated in the Paycheck Protection Program (“PPP”) under the CARES Act whereby loans to small businesses are originated. These loans require forbearance of loan payments for a specified time and also limit our ability to pursue all available remedies in the event of a loan default. If the borrower under the PPP loan fails to qualify for loan forgiveness, if the terms of the program change, or if the SBA determines there is a deficiency in the manner in which any PPP loans were originated, funded or serviced by the Company, we may be subject to repayment risk as well as the heightened risk of holding these loans at unfavorable interest rates as compared to loans to customers that we would have otherwise extended credit. Beginning in the first quarter of 2020, under the guidance of the CARES Act and banking regulators, we offered deferrals of principal and interest payments to certain borrowers financially affected by the COVID-19 pandemic. Some of these borrowers may not be able to return to regular payments at the end of the deferral period, and we may arrange additional deferrals or other types of modifications with these borrowers to accommodate their economic hardship. This may result in higher delinquencies and greater charge-offs in future periods, which would adversely affect our financial condition, including capital and liquidity, or results of operations. In the event our allowance for credit losses is insufficient to cover such losses, our earnings, capital and liquidity could be adversely affected. Strategic Risk. Our financial condition and results of operations may be affected by a variety of external factors that may affect the price or marketability of our products and services, changes in interest rates that may increase our funding costs, reduced demand for our financial products due to economic conditions and the various responses of governmental and nongovernmental authorities to economic instability. The COVID-19 pandemic has significantly increased economic and demand uncertainty, which may impact our ability to effect our strategic priorities, including strategies relating to organic growth and bank 15 acquisitions, and has led to severe disruptions and volatility in the global capital markets. Furthermore, many of the governmental actions in response to the COVID-19 pandemic have been directed toward curtailing household and business activity to contain the COVID-19 pandemic. These actions have been rapidly changing. For example, in many of our markets, local governments acted to temporarily close or restrict the operations of most businesses, and these restrictions could recur if there are future increases in the spread of the virus. Operational Risk. Current and future restrictions on our workforce’s access to our facilities could limit our ability to meet customer servicing expectations and have a material adverse effect on our operations. We rely on business processes and branch activity that largely depend on people and technology, including access to information technology systems as well as information, applications, payment systems and other services provided by third parties. In response to the COVID-19 pandemic, we have modified our business practices with a portion of our employees working remotely to ensure that our operations continue uninterrupted as much as possible. Nonetheless, technology in employees’ homes may not be as robust as in our offices and could cause the networks, information systems, applications, and other tools available to employees to be more limited or less reliable than in our offices. The continuation of these work-from-home measures also introduces additional operational risk, including increased cybersecurity risk. These cyber risks include greater phishing, malware, and other cybersecurity attacks, vulnerability to disruptions of our information technology infrastructure and telecommunications systems for remote operations, increased risk of unauthorized dissemination of confidential information, limited ability to restore the systems in the event of a systems failure or interruption, greater risk of a security breach resulting in destruction or misuse of valuable information, and potential impairment of our ability to perform critical functions, including wiring funds, all of which could expose us to risks of data or financial loss, litigation and liability and could seriously disrupt our operations and the operations of any impacted customers. Interest Rate Risk. Our net interest income, lending activities, deposits and profitability are and are likely to continue to be negatively affected by volatility in interest rates caused by uncertainties stemming from the COVID-19 pandemic. In March 2020, the Federal Reserve lowered the target range for the federal funds rate to a range from 0 to 0.25 percent, citing concerns about the impact of the COVID-19 pandemic on markets and stress in the energy sector. A prolonged period of extremely volatile and unstable market conditions would likely increase our funding costs and negatively affect market risk mitigation strategies. Higher income volatility from changes in interest rates and spreads to benchmark indices will likely cause a loss of future net interest income and a decrease in current fair market values of our assets. Fluctuations in interest rates, or a prolonged period of low interest rates will impact both the level of income and expense recorded on most of our assets and liabilities and the market value of all interest-earning assets and interest-bearing liabilities, which in turn could have a material adverse effect on our net income, operating results, or financial condition. We typically continue to recognize interest income on loans with payment accommodations. If it is later determined that the borrower will be unable to make all payments due, the loan may be classified as nonaccrual, and interest accrued but not collected will be reversed against interest income, which would negatively affect net interest income in the period of reversal. Because there have been no comparable recent global pandemics that resulted in similar global impact, we do not yet know the full extent and long-term impact of the COVID-19 pandemic’s effects on our business, operations, or the global economy as a whole. Any future developments will be highly uncertain and cannot be predicted, including the scope and duration of the COVID-19 pandemic, the effectiveness of our work from home arrangements, third party providers’ ability to support our operation, and any actions taken by governmental authorities and other third parties in response to the COVID-19 pandemic. The uncertain future development of this crisis has and could continue to materially and adversely affect our business, operations, operating results, financial condition, liquidity or capital levels. Regulatory and Litigation Risk. Federal, state and local governments have mandated or encouraged financial services companies to make accommodations to borrowers and other customers financially affected by the COVID-19 pandemic. Legal and regulatory responses to concerns about the COVID-19 pandemic could result in additional regulation or restrictions affecting the conduct of our business in the future. Furthermore, since the inception of the PPP, several banks have been subject to litigation regarding the process and procedures that such banks used in processing applications for the PPP and claims related to agent fees. In addition, some banks have received negative media attention associated with PPP loans. The Company and the Bank are exposed to similar litigation risk and negative media attention risk, from both customers and non-customers that approached the Bank regarding PPP loans, regarding its process and procedures used in processing applications for the PPP, or litigation from agents with respect to agent fees. If any such litigation is filed against the Company or the Bank and is not resolved in a manner favorable to the Company or the Bank, it may result in significant financial liability or adversely affect the Company’s reputation. In addition, litigation can be costly, regardless of outcome. Any financial liability, litigation costs or 16 reputational damage caused by PPP-related litigation or negative media attention could have a material adverse impact on our business, financial condition and results of operations. The PPP has also attracted interest from federal and state enforcement authorities, oversight agencies, regulators and Congressional committees. State Attorneys General and other federal and state agencies may assert that they are not subject to the provisions of the CARES Act and the PPP regulations entitling the Bank to rely on borrower certifications, and they may take more aggressive actions against the Bank for alleged violations of the provisions governing the Bank’s participation in the PPP. Federal and state regulators can impose or request that we consent to substantial sanctions, restrictions and requirements if they determine there are violations of laws, rules or regulations or weaknesses or failures with respect to general standards of safety and soundness, which could adversely affect our business, reputation, results of operation and financial condition. Credit Risk Lending goals may not be attainable. Future demand for additional lending is unclear and uncertain, and opportunities to make loans may be more limited and/or involve risks or terms that we likely would not find acceptable or in our shareholders’ best interest. A failure to meet our lending goals could adversely affect our results of operations, and financial condition, liquidity and capital. Deterioration in the real estate markets, including the secondary market for residential mortgage loans, can adversely affect us. A correction in residential real estate market prices or reduced levels of home sales, could result in lower single family home values, adversely affecting the liquidity and value of collateral securing commercial loans for residential land acquisition, construction and development, as well as residential mortgage loans and residential property collateral securing loans that we hold, mortgage loan originations and gains on the sale of mortgage loans. Declining real estate prices cause higher delinquencies and losses on certain mortgage loans, generally, and particularly on second lien mortgages and home equity lines of credit. Significant ongoing disruptions in the secondary market for residential mortgage loans can limit the market for and liquidity of most residential mortgage loans other than conforming Fannie Mae and Freddie Mac loans. Deteriorating trends could occur, including declines in real estate values, home sales volumes, financial stress on borrowers as a result of job losses or other factors. These could have adverse effects on borrowers that result in higher delinquencies and greater charge-offs in future periods, which would adversely affect our financial condition, including capital and liquidity, or results of operations. In the event our allowance for credit losses on loans is insufficient to cover such losses, our earnings, capital and liquidity could be adversely affected. Our real estate portfolios are exposed if weakness in the Florida housing market or general economy arises. Florida has historically experienced deeper recessions and more dramatic slowdowns in economic activity than other states and a decline in real estate values in Florida can be significantly larger than the national average. Declines in home prices and the volume of home sales in Florida, along with the reduced availability of certain types of mortgage credit, can result in increases in delinquencies and losses in our portfolios of home equity lines and loans, and commercial loans related to residential real estate acquisition, construction and development. Declines in home prices coupled with high or increased unemployment levels or increased interest rates can cause losses which adversely affect our earnings and financial condition, including our capital and liquidity. We are subject to lending concentration risk. Our loan portfolio contains several industry and collateral concentrations including, but not limited to, commercial and residential real estate. Due to the exposure in these concentrations, disruptions in markets, economic conditions, including those resulting from the global response to the COVID-19 pandemic, changes in laws or regulations or other events could cause a significant impact on the ability of borrowers to repay and may have a material adverse effect on our business, financial condition and results of operations. A substantial portion of our loan portfolio is secured by real estate. In weak economies, or in areas where real estate market conditions are distressed, we may experience a higher than normal level of nonperforming real estate loans. The collateral value of the portfolio and the revenue stream from those loans could come under stress, and additional provisions for the allowance for credit losses could be necessitated. Our ability to dispose of foreclosed real estate at prices at or above the respective carrying values could also be impaired, causing additional losses. Commercial real estate (“CRE”) is cyclical and poses risks of loss to us due to our concentration levels and risk of the asset, especially during a difficult economy, including the current stressed economy. As of December 31, 2020, 45% of our loan 17 portfolio was comprised of CRE loans. The banking regulators continue to give CRE lending greater scrutiny, and banks with higher levels of CRE loans are expected to implement improved underwriting, internal controls, risk management policies and portfolio stress testing, as well as higher levels of allowances for possible losses and capital levels as a result of CRE lending growth and exposures. Seacoast Bank has a CRE concentration risk management program and monitors its exposure to CRE; however, there can be no assurance that the program will be effective in managing our concentration in CRE. Nonperforming assets could result in an increase in our provision for credit losses on loans, which could adversely affect our results of operations and financial condition. At December 31, 2020, our nonaccrual loans totaled $36.1 million, or 0.6% of the loan portfolio and our nonperforming assets (which includes nonaccrual loans) were $48.9 million, or 0.6%, of assets. In addition, we had approximately $10.1 million in accruing loans that were 30 days or more delinquent at December 31, 2020. Our nonperforming assets adversely affect our net income in various ways. We generally do not record interest income on nonaccrual loans or OREO, thereby adversely affecting our income, and increasing our loan administration costs. When the only source of repayment expected is the underlying collateral, we are required to mark the related loan to the then fair market value of the collateral, if less than the recorded amount of our investment, which may result in a loss. These loans and OREO also increase our risk profile and the capital our regulators believe is appropriate in light of such risks. We may incur additional losses relating to an increase in nonperforming loans. If economic conditions and market factors negatively and/or disproportionately affect some of our larger loans, then we could see a sharp increase in our total net charge-offs and our provision for credit losses on loans. Any increase in our nonperforming assets and related increases in our provision for losses on loans could negatively affect our business and could have a material adverse effect on our capital, financial condition and results of operations. Decreases in the value of these assets, or the underlying collateral, or in these borrowers’ performance or financial conditions, whether or not due to economic and market conditions beyond our control, could adversely affect our business, results of operations and financial condition. In addition, the resolution of nonperforming assets requires significant commitments of time from management and our personnel, which can be detrimental to the performance of their other responsibilities. There can be no assurance that we will not experience increases in nonperforming loans in the future, or that nonperforming assets will not result in losses in the future. Our allowance for credit losses on loans may prove inadequate or we may be adversely affected by credit risk exposures. Our business depends on the creditworthiness of our customers. We review our allowance for credit losses on loans for adequacy, at a minimum quarterly, considering economic conditions and trends, reasonable and supportable forecasts, collateral values and credit quality indicators, including past charge-off experience and levels of past due loans and nonperforming assets. The determination of the appropriate level of the allowance for credit losses involves a high degree of subjectivity and judgment and requires us to make significant estimates of current credit risks and future trends, all of which may undergo material changes. We cannot be certain that our allowance will be adequate over time to cover credit losses in our portfolio because of unanticipated adverse changes in the economy, market conditions or events adversely affecting specific customers, industries or markets, or borrowers repaying their loans. Generally speaking, the credit quality of our borrowers can deteriorate as a result of economic downturns in our markets. If the credit quality of our customer base or their debt service behavior materially decreases, if the risk profile of a market, industry or group of customers declines or weakness in the real estate markets and other economics were to arise, or if our allowance for credit losses on loans is not adequate, our business, financial condition, including our liquidity and capital, and results of operations could be materially adversely affected. In addition, bank regulatory agencies periodically review our allowance and may require an increase in the provision for credit losses or the recognition of loan charge-offs, based on judgments different than those of management. If charge-offs in future periods exceed the allowance for credit losses on loans, we will need additional provisions to increase the allowance, which would result in a decrease in net income and capital, and could have a material adverse effect on our financial condition and results of operations. Interest Rate Risk We must effectively manage our interest rate risk. The impact of changing interest rates on our results is difficult to predict and changes in interest rates may impact our performance in ways we cannot predict. Our profitability is largely dependent on our net interest income, which is the difference between the interest income paid to us on our loans and investments and the interest we pay to third parties such as our depositors, lenders and debt holders. Changes in interest rates can impact our profits and the fair values of certain of our assets and liabilities. Prolonged periods of unusually low interest rates may have an incrementally adverse effect on our earnings by reducing yields on loans and other earning assets over time. Increases in market interest rates may reduce our customers’ desire to borrow money from us or adversely affect 18 their ability to repay their outstanding loans by increasing their debt service obligations through the periodic reset of adjustable interest rate loans. If our borrowers’ ability to pay their loans is impaired by increasing interest payment obligations, our level of nonperforming assets would increase, producing an adverse effect on operating results. Increases in interest rates can have a material impact on the volume of mortgage originations and re-financings, adversely affecting the profitability of our mortgage finance business. Interest rate risk can also result from mismatches between the dollar amounts of re-pricing or maturing assets and liabilities and from mismatches in the timing and rates at which our assets and liabilities re-price. We actively monitor and manage the balances of our maturing and re-pricing assets and liabilities to reduce the adverse impact of changes in interest rates, but there can be no assurance that we will be able to avoid material adverse effects on our net interest margin in all market conditions. There can be no assurance that we will not be materially adversely affected in the future if economic activity increases and interest rates rise, which may result in our interest expense increasing, and our net interest margin decreasing, if we must offer interest on commercial demand deposits to attract or retain customer deposits. The Federal Reserve has implemented significant economic strategies that have impacted interest rates, inflation, asset values, and the shape of the yield curve, over which the Company has no control and which the Company may not be able to adequately anticipate. In recent years, in response to the recession in 2008 and the following uneven recovery, the Federal Reserve implemented a series of domestic monetary initiatives. Several of these have emphasized so-called quantitative easing strategies, the most recent of which ended during 2014. Since then the Federal Reserve raised rates nine times during 2015-2018, and reduced rates five times during 2019-2020. Further rate changes reportedly are dependent on the Federal Reserve’s assessment of economic data as it becomes available. The Company cannot predict the nature or timing of future changes in monetary, economic, or other policies or the effect that they may have on the Company's business activities, financial condition and results of operations. Our cost of funds may increase as a result of general economic conditions, FDIC insurance assessments, interest rates and competitive pressures. We have traditionally obtained funds through local deposits and thus we have a base of lower cost transaction deposits. Generally, we believe local deposits are a cheaper and more stable source of funds than other borrowings because interest rates paid for local deposits are typically lower than interest rates charged for borrowings from other institutional lenders and reflect a mix of transaction and time deposits, whereas brokered deposits typically are higher cost time deposits. Our costs of funds and our profitability and liquidity are likely to be adversely affected if, and to the extent, we have to rely upon higher cost borrowings from other institutional lenders or brokers to fund loan demand or liquidity needs, and changes in our deposit mix and growth could adversely affect our profitability and the ability to expand our loan portfolio. The expected discontinuation of the London Interbank Offered Rate (“LIBOR”), and the identification and use of alternative replacement reference rates, could adversely affect our revenue, expenses, and the value of the Company's financial instruments, and may subject the Company to litigation risk. In 2017, the United Kingdom’s Financial Conduct Authority, which regulates LIBOR, publicly announced that it intends to stop persuading or compelling banks to submit LIBOR rates after 2021. On November 30, 2020, the Intercontinental Exchange Benchmark Administration, which is the administrator of LIBOR, announced its intention to cease the publication of most U.S. dollar (“USD”) LIBOR settings immediately following the LIBOR publication on June 30, 2023, extending the previously indicated timeline for the discontinuation of the widely used one-month, three-month, and other USD LIBOR benchmarks. In the United States, the Alternative Reference Rate Committee (“ARRC”), a group of market participants including large U.S. financial institutions, assembled by the Federal Reserve Board and the Federal Reserve Bank of New York, was tasked with identifying alternative reference interest rates to replace LIBOR. The Secured Overnight Finance Rate (“SOFR”) has emerged as the ARRC's preferred alternative rate for LIBOR. SOFR is a broad measure of the cost of borrowing cash overnight collateralized by Treasury securities in the repurchase agreement market. At this time, it is not possible to predict how markets will respond to SOFR or other alternative reference rates as the transition away from LIBOR is anticipated to be gradual over the coming years. The consequences of these developments with respect to LIBOR cannot be entirely predicted, and these reforms may cause benchmark rates to perform differently than in the past or have other consequences, which could adversely affect the value of our floating rate obligations, loans, derivatives, and other financial instruments tied to LIBOR rates. The Company has formed a LIBOR transition steering committee that is responsible for overseeing the execution of the Company's enterprise-wide LIBOR transition program, and for evaluating and mitigating the risks associated with the transition from LIBOR. The LIBOR transition program includes a comprehensive review of the financial products, agreements, contracts 19 and business processes that may use LIBOR as a reference rate, and the development and execution of a strategy to transition away from LIBOR, with appropriate consideration of the potential financial, customer, counterparty, regulatory and legal impacts. As of December 31, 2020, the Company has identified approximately $400 million in loans for which the repricing index is tied to LIBOR. The Company's swap agreements and other derivatives are governed by the International Swap Dealers Association (“ISDA”). ISDA has developed fallback language for swap agreements and has established a protocol to allow counterparties to modify legacy trades to include the new fallback language. The Company also invests in securities and has issued subordinated debt tied to LIBOR. The Company continues to monitor regulatory and legislative activity with regard to these products to identify any necessary actions and facilitate the transition to alternative reference rates. The market transition away from LIBOR to an alternative reference rate is complex. We may incur significant expense in effecting the transition and we may be subject to disputes or litigation with our borrowers or counterparties over the appropriateness or comparability to LIBOR of the replacement reference rates. The replacement reference rates could also result in a reduction in our interest income. We may also receive inquiries and other actions from regulators about the Company's preparation and readiness for the replacement of LIBOR with alternative reference rates. Liquidity Risk Liquidity risks could affect operations and jeopardize our financial condition. Liquidity is essential to our business. An inability to raise funds through deposits, borrowings, the sale of loans and other sources could have a substantial negative effect on our liquidity. Our funding sources include customer deposits, federal funds purchases, securities sold under repurchase agreements, and short- and long-term debt. We are also members of the Federal Home Loan Bank of Atlanta (the “FHLB”) and the Federal Reserve Bank of Atlanta, where we can obtain advances collateralized with eligible assets. We maintain a portfolio of securities that can be used as a secondary source of liquidity. Other sources of liquidity available to us or Seacoast Bank include the acquisition of additional deposits, the issuance and sale of debt securities, and the issuance and sale of preferred or common securities in public or private transactions. Our access to funding sources in amounts adequate or on terms which are acceptable to us could be impaired by other factors that affect us specifically or the financial services industry or economy in general. Factors that could detrimentally impact our access to liquidity sources include a downturn in the markets in which our loans are concentrated or adverse regulatory action against us. In addition, our access to deposits may be affected by the liquidity and/or cash flow needs of depositors. Although we have historically been able to replace maturing deposits and FHLB advances as necessary, we might not be able to replace such funds in the future and can lose a relatively inexpensive source of funds and increase our funding costs if, among other things, customers move funds out of bank deposits and into alternative investments, such as the stock market, that may be perceived as providing superior expected returns. We may be required to seek additional regulatory capital through capital raises at terms that may be very dilutive to existing shareholders. Our ability to borrow could also be impaired by factors that are not specific to us, such as disruptions in the financial markets or negative views and expectations about the prospects for the financial services industry. Our ability to receive dividends from our subsidiaries could affect our liquidity and ability to pay interest on our trust preferred securities or reinstate dividends. We are a legal entity separate and distinct from Seacoast Bank and our other subsidiaries. Our primary source of cash, other than securities offerings, is dividends from Seacoast Bank. These dividends are the principal source of funds to pay dividends on our common stock, interest on our trust preferred securities and interest and principal on our debt. Various laws and regulations limit the amount of dividends that Seacoast Bank may pay us, as further described in “Supervision and Regulation - Payment of Dividends.” Also, our right to participate in a distribution of assets upon a subsidiary’s liquidation or reorganization is subject to the prior claims of the subsidiary’s creditors. Limitations on our ability to receive dividends from our subsidiaries could have a material adverse effect on our liquidity and on our ability to pay dividends on common stock. Additionally, if our subsidiaries’ earnings are not sufficient to make dividend payments to us while maintaining adequate capital levels, we may not be able to make payments on our trust preferred securities or reinstate dividend payments to our common shareholders. Business and Strategic Risks Our future success is dependent on our ability to compete effectively in highly competitive markets. We operate in markets throughout the State of Florida, each with unique characteristics and opportunities. Our future growth and success will depend on our ability to compete effectively in these and other potential markets. We compete for loans, 20 deposits and other financial services in geographic markets with other local, regional and national commercial banks, thrifts, credit unions, mortgage lenders, and securities and insurance brokerage firms. Many of our competitors offer products and services different from us, and have substantially greater resources, name recognition and market presence than we do, which benefits them in attracting business. Larger competitors may be able to price loans and deposits more aggressively than we can, and have broader customer and geographic bases to draw upon. Consumers may decide not to use banks to complete their financial transactions, which could adversely affect our net income. Technology and other changes now allow parties to complete financial transactions without banks. For example, consumers can pay bills, transfer funds directly and obtain loans without banks. This process could result in the loss of interest and fee income, as well as the loss of customer deposits and the income generated from those deposits. Non-bank financial technology providers invest substantial resources in developing and designing new technology, particularly digital and mobile technology, and are beginning to offer more traditional banking products either directly or through bank partnerships. Further, clients may choose to conduct business with other market participants who engage in business or offer products in areas we deem speculative or risky, such as cryptocurrencies. Increased competition may negatively affect our earnings by creating pressure to lower prices or credit standards on our products and services requiring additional investment to improve the quality and delivery of our technology and/or reducing our market share, or affecting the willingness of our clients to do business with us. In addition, the widespread adoption of new technologies, including internet banking services, mobile banking services, cryptocurrencies and payment systems, could require substantial expenditures to modify or adapt our existing products and services as we grow and develop our internet banking and mobile banking channel strategies in addition to remote connectivity solutions. We might not be successful in developing or introducing new products and services, integrating new products or services into our existing offerings, responding or adapting to changes in consumer behavior, preferences, spending, investing and/or saving habits, achieving market acceptance of our products and services, reducing costs in response to pressures to deliver products and services at lower prices or sufficiently developing and maintaining loyal customers. Further, we may experience a decrease in customer deposits if customers perceive alternative investments, such as the stock market, as providing superior expected returns. When customers move money out of bank deposits in favor of alternative investments, we may lose a relatively inexpensive source of funds, and be forced to rely more heavily on borrowings and other sources of funding to fund our business and meet withdrawal demands, thereby increasing our funding costs and adversely affecting our net interest margin. Hurricanes or other adverse weather events, as well as climate change, could negatively affect our local economies or disrupt our operations, which would have an adverse effect on our business and results of operations. Our market areas in Florida are susceptible to hurricanes, tropical storms and related flooding and wind damage. Such weather events can disrupt operations, result in damage to properties and negatively affect the local economies in the markets where we operate. We cannot predict whether or to what extent damage that may be caused by future hurricanes will affect our operations or the economies in our current or future market areas, but such weather events could result in a decline in loan originations, a decline in the value or destruction of properties securing our loans and an increase in delinquencies, foreclosures or loan losses. Our business and results of operations may be adversely affected by these and other negative effects of future hurricanes, tropical storms, related flooding and wind damage and other similar weather events. As a result of the potential for such weather events, many of our customers have incurred significantly higher property and casualty insurance premiums on their properties located in our markets, which may adversely affect real estate sales and values in our markets. Climate change may be increasing the nature, severity, and frequency of adverse weather conditions, making the impact from these types of natural disasters on us or customers worse. Further, concerns over the long-term impacts of climate change have led and will continue to lead to governmental efforts around the world to mitigate those impacts. Investors, consumers and businesses also may change their behavior on their own as a result of these concerns. The state of Florida could be disproportionately impacted by long-term climate changes. We and our customers may face cost increases, asset value reductions (which could impact customer creditworthiness), operating process changes, changes in demand for products and services, and the like resulting from new laws, regulations, and changing consumer and investor preferences regarding our, or other companies', response to climate change. Our efforts to take these risks into account in making lending and other decisions, including by increasing our business with climate-friendly companies, 21 may not be effective in protecting us from the negative impact of new laws and regulations or changes in consumer or business behavior. Changes in accounting rules applicable to banks could adversely affect our financial condition and results of operations. From time to time, the Financial Accounting Standards Board (the “FASB”) and the SEC change the financial accounting and reporting standards that govern the preparation of our financial statements. These changes can be hard to predict and can materially impact how we record and report our financial condition and results of operations. In some cases, we could be required to apply a new or revised standard retroactively, resulting in a restatement of our prior period financial statements. On January 1, 2020, we implemented FASB’s Accounting Standards Codification (“ASC”) Topic 326, Financial Instruments - Credit Losses. This guidance replaced the existing “incurred loss” methodology for financial assets measured at amortized cost, and introduced requirements to estimate current expected credit losses (“CECL”). Under the incurred loss methodology, credit losses were recognized only when the losses were probable or had been incurred; under CECL, companies are required to recognize the full amount of expected credit losses for the lifetime of the financial assets, based on historical experience, current conditions and reasonable and supportable forecasts. This change requires earlier recognition of credit losses that are deemed expected but not yet probable, and we expect will result in higher reserves for credit losses and higher volatility in the quarterly provision for credit losses. The CECL model also impacts the accounting for bank acquisition activity by requiring the recognition of expected credit losses on acquired loans at the date of acquisition, in addition to the purchase discount, if any. With the exception of purchased loans with credit deterioration (“PCD”), this day-one recognition of the allowance for credit losses is recorded with an offset to net income. For PCD loans, the initial estimate of expected credit losses is recognized as an adjustment to the amortized cost basis of the loan at acquisition (i.e., a balance sheet gross-up). The anti-takeover provisions in our Articles of Incorporation and under Florida law may make it more difficult for takeover attempts that have not been approved by our board of directors. Florida law and our Articles of Incorporation include anti-takeover provisions, such as provisions that encourage persons seeking to acquire control of us to consult with our board of directors, and which enable the board of directors to negotiate and give consideration on behalf of us and our shareholders and other constituencies to the merits of any offer made. Such provisions, as well as super-majority voting and quorum requirements, and a staggered board of directors, may make any takeover attempts and other acquisitions of interests in us, by means of a tender offer, open market purchase, a proxy fight or otherwise, that have not been approved by our board of directors more difficult and more expensive. These provisions may discourage possible business combinations that a majority of our shareholders may believe to be desirable and beneficial. As a result, our board of directors may decide not to pursue transactions that would otherwise be in the best interests of holders of our common stock. Operational Risk The implementation of other new lines of business or new products and services may subject us to additional risk. We continuously evaluate our service offerings and may implement new lines of business or offer new products and services within existing lines of business in the future. There are substantial risks and uncertainties associated with these efforts. In developing and marketing new lines of business and/or new products and services, we undergo a process to assess the risks of the initiative, and invest significant time and resources to build internal controls, policies and procedures to mitigate those risks, including hiring experienced management to oversee the implementation of the initiative. Initial timetables for the introduction and development of new lines of business and/or new products or services may not be achieved and price and profitability targets may not prove feasible. External factors, such as compliance with regulations, competitive alternatives, and shifting market preferences, may also impact the successful implementation of a new line of business and/or a new product or service. Furthermore, any new line of business and/or new product or service could require the establishment of new key and other controls and have a significant impact on our existing system of internal controls. Failure to successfully manage these risks in the development and implementation of new lines of business and/or new products or services could have a material adverse effect on our business and, in turn, our financial condition and results of operations. Employee misconduct could expose us to significant legal liability and reputational harm. We are vulnerable to reputational harm because we operate in an industry in which integrity and the confidence of our customers are of critical importance. Our employees could engage in fraudulent, illegal, wrongful or suspicious activities, and/ or activities resulting in consumer harm that adversely affects our customers and/or our business. The precautions we take to 22 detect and prevent such misconduct may not always be effective, such misconduct may result in regulatory sanctions and/or penalties, serious harm to our reputation, financial condition, customer relationships or the ability to attract new customers. In addition, improper use or disclosure of confidential information by our employees, even if inadvertent, could result in serious harm to our reputation, financial condition and current and future business relationships. The precautions we take to detect and prevent such misconduct may not always be effective. We are subject to losses due to fraudulent and negligent acts on the part of loan applicants, mortgage brokers, other vendors and our employees. When we originate loans, we rely heavily upon information supplied by loan applicants and third parties, including the information contained in the loan application, property appraisal, title information and employment and income documentation provided by third parties. If any of this information is misrepresented and such misrepresentation is not detected prior to loan funding, we generally bear the risk of loss associated with the misrepresentation. If we fail to maintain an effective system of disclosure controls and procedures, including internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud, which could have a material adverse effect on our business, results of operations and financial condition. In addition, current and potential shareholders could lose confidence in our financial reporting, which could harm the trading price of our common stock. Management regularly monitors, reviews and updates our disclosure controls and procedures, including our internal control over financial reporting. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable assurances that the controls will be effective. Any failure or circumvention of our controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on our business, results of operations and financial condition. Failure to achieve and maintain an effective internal control environment could prevent us from accurately reporting our financial results, preventing or detecting fraud or providing timely and reliable financial information pursuant to our reporting obligations, which could result in a material weakness in our internal controls over financial reporting and the restatement of previously filed financial statements and could have a material adverse effect on our business, financial condition and results of operations. Further, ineffective internal controls could cause our investors to lose confidence in our financial information, which could affect the trading price of our common stock. Our operations rely on external vendors. We rely on certain external vendors to provide products and services necessary to maintain our day-to-day operations, particularly in the areas of operations, treasury management systems, information technology and security, exposing us to the risk that these vendors will not perform as required by our agreements. An external vendor’s failure to perform in accordance with our agreement could be disruptive to our operations, which could have a material adverse impact on our business, financial condition and results of operations. Our regulators also impose requirements on us with respect to monitoring and implementing adequate controls and procedures in connection with our third party vendors. From time to time, we may decide to retain new vendors for new or existing products and services. Transition to these new vendors may not proceed as anticipated and could negatively impact our customers or our ability to conduct business, which, in turn, could have an adverse effect on our business, results of operations and financial condition. To mitigate this risk, the Company has an established process to oversee vendor relationships. We must effectively manage our information systems risk. We rely heavily on our communications and information systems to conduct our business. The financial services industry is undergoing rapid technological changes with frequent introductions of new technology-driven products, services and methods of delivery. Our ability to compete successfully depends in part upon our ability to use technology to provide products and services that will satisfy customer demands. We have and will continue to make technology investments to achieve process improvements and increase efficiency. Many of the Company’s competitors invest substantially greater resources in technological improvements than we do. We may not be able to effectively select, develop or implement new technology-driven products and services or be successful in marketing these products and services to our customers, which may negatively affect our business, results of operations or financial condition. Disruptions to our information systems or security breaches could adversely affect our business and reputation. Our communications and information systems remain vulnerable to unexpected disruptions and failures. Any failure or interruption of these systems could impair our ability to serve our customers and to operate our business and could damage our 23 reputation, result in a loss of business, subject us to additional regulatory scrutiny or enforcement or expose us to civil litigation and possible financial liability. While we have developed extensive recovery plans, we cannot assure that those plans will be effective to prevent adverse effects upon us and our customers resulting from system failures. While we maintain an insurance policy which we believe provides sufficient coverage at a manageable expense for an institution of our size and scope with similar technological systems, we cannot assure that this policy would be sufficient to cover all related financial losses and damages should we experience any one or more of our or a third party’s systems failing or experiencing a cyber-attack. We collect and store sensitive data, including personally identifiable information of our customers and employees as well as sensitive information related to our operations. Our collection of such Company and customer data is subject to extensive regulation and oversight. Computer break-ins of our systems or our customers’ systems, thefts of data and other breaches and criminal activity may result in significant costs to respond, liability for customer losses if we are at fault, damage to our customer relationships, regulatory scrutiny and enforcement and loss of future business opportunities due to reputational damage. Although we, with the help of third-party service providers, will continue to implement security technology and establish operational procedures to protect sensitive data, there can be no assurance that these measures will be effective. We advise and provide training to our customers regarding protection of their systems, but there is no assurance that our advice and training will be appropriately acted upon by our customers or effective to prevent losses. In some cases we may elect to contribute to the cost of responding to cybercrime against our customers, even when we are not at fault, in order to maintain valuable customer relationships. In our ordinary course of business, we rely on electronic communications and information systems to conduct our businesses and to store sensitive data, including financial information regarding our customers. The integrity of information systems of financial institutions are under significant threat from cyber-attacks by third parties, including through coordinated attacks sponsored by foreign nations and criminal organizations to disrupt business operations and other compromises to data and systems for political or criminal purposes. We employ an in-depth, layered, lines of defense approach that leverages people, processes and technology to manage and maintain cyber security and other information security controls. Notwithstanding the strength of our defensive measures, the threat from cyber-attacks is severe, attacks are sophisticated and attackers respond rapidly to changes in defensive measures, and there is no assurance that our response to any cyber-attack or system interruption, breach or failure will be fully effective to mitigate and remediate the issues resulting from such an event, including the costs, reputational harm and litigation challenges that we may face as a result. Cyber security risks may also occur with our third-party service providers, and may interfere with their ability to fulfill their contractual obligations to us, with attendant potential for financial loss or liability that could adversely affect our financial condition or results of operations. We offer our clients the ability to bank remotely and provide other technology based products and services, which services include the secure transmission of confidential information over the Internet and other remote channels. To the extent that our clients' systems are not secure or are otherwise compromised, our network could be vulnerable to unauthorized access, malicious software, phishing schemes and other security breaches. To the extent that our activities or the activities of our clients or third- party service providers involve the storage and transmission of confidential information, security breaches and malicious software could expose us to claims, regulatory scrutiny, litigation and other possible liabilities. While to date we have not experienced a significant compromise, significant data loss or material financial losses related to cyber security attacks, our systems and those of our clients and third-party service providers are under constant threat and it is possible that we could experience a significant event in the future. We may suffer material financial losses related to these risks in the future or we may be subject to liability for compromises to our client or third-party service provider systems. Any such losses or liabilities could adversely affect our financial condition or results of operations, and could expose us to reputation risk, the loss of client business, increased operational costs, as well as additional regulatory scrutiny, possible litigation, and related financial liability. These risks also include possible business interruption, including the inability to access critical information and systems. In addition, as the domestic and foreign regulatory environment related to information security, data collection and use, and privacy becomes increasingly rigorous, with new and constantly changing requirements applicable to our business, compliance with those requirements could also result in additional costs. Compliance Risk We operate in a heavily regulated environment. Regulatory compliance burdens and associated costs can affect our business, including our reputation, the value of our securities, and the results of our operations.. We and our subsidiaries are regulated by several regulators, including, but not limited to, the Federal Reserve, the OCC, the FDIC, the CFPB, the Small Business Administration, the SEC and NASDAQ. Our success is affected by state and federal regulations affecting banks and bank holding companies, the securities markets and banking, securities and insurance regulators. Banking regulations are primarily intended to protect consumers and depositors, not shareholders. The financial services industry also is subject to frequent legislative and regulatory changes and proposed changes, the effects of which cannot be predicted. These changes, if adopted, could require us to maintain more capital, liquidity and risk controls which 24 could adversely affect our growth, profitability and financial condition. Any such changes in law can impact the profitability of our business activities, require changes to our operating policies and procedures, or otherwise adversely impact our business. Further, we expect to continue to spend significant amounts of time and money on compliance with various corporate governance and financial reporting requirements under the Sarbanes-Oxley Act of 2002, as well as rules and regulations adopted by the SEC, the Public Accounting Oversight Board and NASDAQ. Our failure to track and comply with the various rules may materially adversely affect our reputation, ability to obtain the necessary certifications to financial statements, and the value of our securities. Additionally, the CFPB has issued mortgage-related rules required under the Dodd-Frank Act addressing borrower ability-to- repay and qualified mortgage standards. The CFPB has also issued rules for loan originators related to compensation, licensing requirements, administration capabilities and restrictions on pursuance of delinquent borrowers. These rules could have a negative effect on the financial performance of Seacoast Bank's mortgage lending operations such as limiting the volume of mortgage originations and sales into the secondary market, increased compliance burden and impairing Seacoast Bank's ability to proceed against certain delinquent borrowers with timely and effective collection efforts. Pursuant to Section 165 of the Dodd-Frank Act, banks with greater than $10 billion in total consolidated assets are subject to certain additional regulatory requirements, including limits on the debit card interchange fees that such banks may collect, changes in the manner in which assessments for FDIC deposit insurance are calculated, and providing the authority to the CFPB to supervise and examine such banks. If Seacoast Bank grows to exceed $10 billion in total assets, we would be subject to additional federal regulations, which could materially and adversely affect our business. Additionally, compliance with the Dodd-Frank Act's requirements may necessitate that we hire to contract with additional compliance or other personnel, design and implement additional internal controls, or incur other significant expenses, any of which could have a material adverse effect on our business, financial condition or results of operations. We are required to maintain capital to meet regulatory requirements, and if we fail to maintain sufficient capital, whether due to losses, growth opportunities, or an inability to raise additional capital or otherwise, our financial condition, liquidity and results of operations, as well as our compliance with regulatory requirements, would be adversely affected. Both we and Seacoast Bank must meet regulatory capital requirements and maintain sufficient liquidity and our regulators may modify and adjust such requirements in the future. Our ability to raise additional capital, when and if needed in the future, will depend on conditions in the capital markets, general economic conditions and a number of other factors, including investor perceptions regarding the banking industry and the market, governmental activities, many of which are outside our control, and on our financial condition and performance. Accordingly, we cannot assure you that we will be able to raise additional capital if needed or on terms acceptable to us. If we fail to meet these capital and other regulatory requirements, our financial condition, liquidity and results of operations would be materially and adversely affected. Although the Company currently complies with all capital requirements, we may be subject to more stringent regulatory capital ratio requirements in the future and we may need additional capital in order to meet those requirements. Our failure to remain “well capitalized” for bank regulatory purposes could affect customer confidence, our ability to grow, our costs of funds and FDIC insurance costs, our ability to pay dividends on common stock, make distributions on our trust preferred securities, our ability to make acquisitions, and our business, results of operations and financial condition, generally. Under FDIC rules, if Seacoast Bank ceases to be a “well capitalized” institution for bank regulatory purposes, its ability to accept brokered deposits and the interest rates that it pays may both be restricted. Federal banking agencies periodically conduct examinations of our business, including for compliance with laws and regulations, and our failure to comply with any supervisory actions to which we are or become subject as a result of such examinations may adversely affect us. The Federal Reserve and the OCC periodically conduct examinations of our business and Seacoast Bank’s business, including for compliance with laws and regulations, and Seacoast Bank also may be subject to future regulatory examinations by the CFPB as discussed in the “Supervision and Regulation” section above. If, as a result of an examination, the Federal Reserve, the OCC and/or the CFPB were to determine that the financial condition, capital resources, asset quality, asset concentrations, earnings prospects, management, liquidity, sensitivity to market risk, or other aspects of any of our or Seacoast Bank’s operations had become unsatisfactory, or that we or our management were in violation of any law, regulation or guideline in effect from time to time, the regulators may take a number of different remedial actions as they deem appropriate. These actions include the power to enjoin “unsafe or unsound” practices, to require affirmative actions to correct any conditions resulting from any violation or practice, to issue an administrative order that can be judicially enforced, to direct an increase in our 25 capital, to restrict our growth, to change the composition of our concentrations in portfolio or balance sheet assets, to assess civil monetary penalties against our officers or directors or to remove officers and directors. Higher FDIC deposit insurance premiums and assessments could adversely affect our financial condition. FDIC insurance premiums we pay may change and be significantly higher in the future. Market developments may significantly deplete the insurance fund of the FDIC and reduce the ratio of reserves to insured deposits, thereby making it requisite upon the FDIC to charge higher premiums prospectively. Additionally, if we grow to more than $10 billion in total assets, the method that the FDIC uses to determine the amount of our deposit insurance premium will change. Any increases in our assessment rate, future special assessments, or required prepayments in FDIC insurance premiums could reduce our profitability or limit our ability to pursue certain business opportunities, which could have a material adverse effect on our assets, business, cash flow, condition (financial or otherwise), liquidity, prospects or results of operations. Tax law changes and interpretations may have a negative impact on our earnings. The enactment of the Tax Reform Act, has had, and is expected to continue to have, far reaching and significant effects on us, our customers and the U.S. economy. Further, U.S. tax authorities may at any time clarify and/or modify legislation, administration or judicial changes or interpretations the income tax treatment of corporations. Such changes could adversely affect us, either directly or as a result of the effects on our customers. While lower income tax rates should result in improved net income performance over prospective periods, the extent of the benefit will be influenced by the competitive environment and other factors. As of December 31, 2020, we had net deferred tax assets (“DTAs”) of $23.6 million, based on management’s estimation of the likelihood of those DTAs being realized. These and future DTAs may be reduced in the future if our estimates of future taxable income from our operations and tax planning strategies do not support the amounts recorded. Management expects to realize the $23.6 million in net DTAs well in advance of the statutory carryforward period, based on its forecast of future taxable income. We consider positive and negative evidence, including the impact of reversals of existing taxable temporary differences, tax planning strategies and projected earnings within the statutory tax loss carryover period. This process requires significant judgment by management about matters that are by nature uncertain. If we were to conclude that significant portions of our DTAs were not more likely than not to be realized (due to operating results or other factors), a requirement to establish a valuation allowance could adversely affect our financial position and results of operations. The amount of net operating loss carry-forwards and certain other tax attributes realizable annually for income tax purposes may be reduced by an offering and/or other sales of our capital securities, including transactions in the open market by five percent or greater shareholders, if an ownership change is deemed to occur under Section 382 of the Internal Revenue Code (“Section 382”). The determination of whether an ownership change has occurred under Section 382 is highly fact-specific and can occur through one or more acquisitions of capital stock (including open market trading) if the result of such acquisitions is that the percentage of our outstanding common stock held by shareholders or groups of shareholders owning at least 5% of our common stock at the time of such acquisition, as determined under Section 382, is more than 50 percentage points higher than the lowest percentage of our outstanding common stock owned by such shareholders or groups of shareholders within the prior 26 three-year period. Management does not believe any stock offerings, issuances, or reverse stock split have had any negative implications for the Company under Section 382 to date. Merger-Related Risks Future acquisition and expansion activities may disrupt our business, dilute existing shareholders and adversely affect our operating results. We periodically evaluate potential acquisitions and expansion opportunities. To the extent we grow through acquisition, we cannot assure you that we will be able to adequately or profitably manage this growth. Acquiring other banks, branches or businesses, as well as other geographic and product expansion activities, involve various risks including: • • • • • • • • • • • • risks of unknown or contingent liabilities; unanticipated costs and delays; risks that acquired new businesses do not perform consistent with our growth and profitability expectations; risks of entering new market or product areas where we have limited experience; risks that growth will strain our infrastructure, staff, internal controls and management, which may require additional personnel, time and expenditures; exposure to potential asset quality issues with acquired institutions; difficulties, expenses and delays of integrating the operations and personnel of acquired institutions, and start-up delays and costs of other expansion activities; potential disruptions to our business; possible loss of key employees and customers of acquired institutions; potential short-term decrease in profitability; inaccurate estimates of value assigned to acquired assets; and diversion of our management’s time and attention from our existing operations and businesses. Attractive acquisition opportunities may not be available to us in the future. While we seek continued organic growth, we anticipate continuing to evaluate merger and acquisition opportunities presented to us in our core markets and beyond. The number of financial institutions headquartered in Florida, the Southeastern United States, and across the country continues to decline through merger and other activity. We expect that other banking and financial companies, many of which have significantly greater resources, will compete with us to acquire financial services businesses. This competition, as the number of appropriate merger targets decreases, could increase prices for potential acquisitions which could reduce our potential returns, and reduce the attractiveness of these opportunities to us. Also, acquisitions are subject to various regulatory approvals. If we fail to receive the appropriate regulatory approvals, we will not be able to consummate an acquisition that we believe is in our best interests. Among other things, our regulators consider our capital, liquidity, profitability, regulatory compliance, including with respect to anti-money laundering (“AML”) obligations, consumer protection laws and CRA obligations and levels of goodwill and intangibles when considering acquisition and expansion proposals. Any acquisition could be dilutive to our earnings and shareholders’ equity per share of our common stock. Our business strategy includes significant growth plans, and our financial condition and results of operations could be negatively affected if we fail to grow or fail to manage our growth effectively, or if we fail to successfully integrate our acquisitions or to realize the anticipated benefits of them. We intend to continue to pursue an organic growth strategy for our business while also regularly evaluating potential acquisitions and expansion opportunities. If appropriate opportunities present themselves, we expect to engage in selected acquisitions of financial institutions, branch acquisitions and other business growth initiatives or undertakings. There can be no assurance that we will successfully identify appropriate opportunities, that we will be able to negotiate or finance such activities or that such activities, if undertaken, will be successful. While we have substantial experience in successfully integrating institutions we have acquired, we may encounter difficulties during integration, such as the loss of key employees, the 27 disruption of operations and businesses, loan and deposit attrition, customer loss and revenue loss, possible inconsistencies in standards, control procedures and policies, and unexpected issues with expected branch closures costs, operations, personnel, technology and credit, all of which could divert resources from regular banking operations. Achieving the anticipated benefits of these mergers is subject to a number of uncertainties, including whether we integrate these institutions in an efficient and effective manner, governmental actions affecting the financial industry generally, and general competitive factors in the marketplace. Failure to achieve these anticipated benefits could result in a reduction in the price of our shares as well as in increased costs, decreases in the amount of expected revenues and diversion of management's time an energy and could materially and adversely affect our business, financial condition and results of operations. There are risks associated with our growth strategy. To the extent that we grow through acquisitions, there can be no assurance that we will be able to adequately or profitably manage this growth. Acquiring other banks, branches or other assets, as well as other expansion activities, involves various risks including the risks of incorrectly assessing the credit quality of acquired assets, encountering greater than expected costs of integrating acquired banks or branches into us, the risk of loss of customers and/or employees of the acquired institution or branch, executing cost savings measures, not achieving revenue enhancements and otherwise not realizing the transaction’s anticipated benefits. Our ability to address these matters successfully cannot be assured. In addition, our strategic efforts may divert resources or management’s attention from ongoing business operations, may require investment in integration and in development and enhancement of additional operational and reporting processes and controls and may subject us to additional regulatory scrutiny. Our growth initiatives may also require us to recruit and retain experienced personnel to assist in such initiatives. Accordingly, the failure to identify and retain such personnel would place significant limitations on our ability to successfully execute our growth strategy. In addition, to the extent we expand our lending beyond our current market areas, we could incur additional risks related to those new market areas. We may not be able to expand our market presence in our existing market areas or successfully enter new markets. If we do not successfully execute our acquisition growth plan, it could adversely affect our business, financial condition, results of operations, reputation and growth prospects. In addition, if we were to conclude that the value of an acquired business had decreased, that conclusion may result in an impairment charge to goodwill or other tangible or intangible assets, which would adversely affect our results of operations. While we believe we have the executive management resources and internal systems in place to successfully manage our future growth, there can be no assurance growth opportunities will be available or that we will successfully manage our growth. Additionally, we may pursue divestitures of non-strategic branches or other assets. Such divestitures involve various risks, including the risks of not being able to timely or fully replace liquidity previously provided by deposits which may be transferred as part of a divestiture, which could adversely affect our financial condition and results of operations. General Risk Factors Shares of our common stock are not insured deposits and may lose value. Shares of our common stock are not savings accounts, deposits or other obligations of any depository institution and are not insured or guaranteed by the FDIC or any other governmental agency or instrumentality, any other deposit insurance fund or by any other public or private entity, and are subject to investment risk, including the possible loss of principal. Any future economic downturn could have a material adverse effect on our capital, financial condition, results of operations, and future growth. Management continually monitors market conditions and economic factors throughout our footprint. If conditions were to worsen nationally, regionally or locally, then we could see a sharp increase in our total net charge-offs and also be required to significantly increase our allowance for credit losses. Furthermore, the demand for loans and our other products and services could decline. An increase in our non-performing assets and related increases in our provision for credit losses, coupled with a potential decrease in the demand for loans and our other products and services, could negatively affect our business and could have a material adverse effect on our capital, financial condition, results of operations and future growth. Our customers may also be adversely impacted by changes in regulatory, trade (including tariffs) and tax policies and laws, all of which could reduce demand for loans and adversely impact our borrowers' ability to repay our loans. In addition, international economic uncertainty could also impact the U.S. financial markets by potentially suppressing stock prices, including ours, and adding it to overall market volatility, which could adversely affect our business. The effects of any economic downturn could continue for many years after the downturn is considered to have ended. 28 A reduction in consumer confidence could negatively impact our results of operations and financial condition. Significant market volatility driven in part by concerns relating to, among other things, actions by the U.S. Congress or imposed through Executive Order by the President of the United States, as well as global political actions or events, including natural disasters, health emergencies or pandemics, could adversely affect the U.S. or global economies, with direct or indirect impacts on the Company and our business. Results could include reduced consumer and business confidence, credit deterioration, diminished capital markets activity, and actions by the Federal Reserve Board impacting interest rates or other U.S. monetary policy. Item 1B. Unresolved Staff Comments None. Item 2. Properties Seacoast maintains its corporate headquarters in a 68,000 square foot, three story building at 815 Colorado Avenue in Stuart, Florida. The building is owned by Seacoast Bank. Seacoast Bank owns or leases all of the buildings in which its business operates. At December 31, 2020, Seacoast Bank had 51 branch offices, stand-alone commercial lending offices, and its main office located in Florida. For additional information regarding properties, please refer to Notes H and L of the Notes to Consolidated Financial Statements. Item 3. Legal Proceedings The Company and its subsidiaries are subject, in the ordinary course, to litigation incidental to the businesses in which they are engaged. Management presently believes that none of the legal proceedings to which they are a party are likely to have a material effect on the Company's consolidated financial position, operating results or cash flows, although no assurance can be given with respect to the ultimate outcome of any such claim or litigation. Item 4. Mine Safety Disclosures Not applicable. Part II Item 5. Market For Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Holders of the Company's common stock are entitled to one vote per share on all matters presented to shareholders for their vote, as provided in our Articles of Incorporation, as amended. The Company's common stock is traded under the symbol “SBCF” on the NASDAQ Global Select Market (“NASDAQ”). As of January 31, 2021, there were 55,249,870 shares of the Company's common stock outstanding, held by approximately 2,350 record holders. Dividends from Seacoast Bank are the Company's primary source of funds to pay dividends to its shareholders. Under the National Bank Act, national banks may in any calendar year, without the approval of the OCC, pay dividends to the extent of net profits for that year, plus retained net profits for the preceding two years (less any required transfers to surplus). The need for Seacoast Bank to maintain adequate capital also limits dividends that may be paid to the Company. Additional information regarding restrictions on the ability of Seacoast Bank to pay dividends to the Company is contained in Note C of the Notes to Consolidated Financial Statements. See “Item 1. Business- Payment of Dividends” of this Form 10-K for information with respect to the regulatory restrictions on dividends. 29 Securities Authorized for Issuance Under Equity Compensation Plans See the information included under Part III, Item 12, which is incorporated in response to this item by reference. Repurchase of Common Stock On December 17, 2020, the Company's Board of Directors authorized the Company to repurchase up to $100 million of its shares of outstanding common stock. Under the share repurchase program, which will expire on December 31, 2021, repurchases will be made, if at all, in accordance with applicable securities laws and may be made from time to time in the open market, by block purchase or by negotiated transactions. The amount and timing of repurchases, if any, will be based on a variety of factors, including share acquisition price, regulatory limitations, market conditions and other factors. The program does not obligate the Company to purchase any of its shares, and may be terminated or amended by the Board of Directors at any time prior to its expiration date. As of December 31, 2020, no shares of the Company's common stock had been repurchased under the program. Item 6. Selected Financial Data Five years of selected financial data of the Company is set forth commencing on page 79. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations The purpose of this discussion and analysis is to aid in understanding significant changes in the financial condition of Seacoast Banking Corporation of Florida and its subsidiaries (“Seacoast” or the “Company”) and their results of operations. Nearly all of the Company’s operations are contained in its banking subsidiary, Seacoast National Bank (“Seacoast Bank” or the “Bank”). Such discussion and analysis should be read in conjunction with the Company's Condensed Consolidated Financial Statements and the related notes included in this report. The emphasis of this discussion will be on the years ended December 31, 2020 and 2019. Additional information about the Company’s financial condition and results of operations in 2018 and changes in the Company’s financial condition and results of operations from 2018 to 2019 may be found in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. This discussion and analysis contains statements that may be considered “forward-looking statements” as defined in, and subject to the protections of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. See the “Special Cautionary Notice Regarding Forward-Looking Statements” for additional information regarding forward-looking statements. For purposes of the following discussion, the words “Seacoast,” or the “Company,” refer to the combined entities of Seacoast Banking Corporation of Florida and its direct and indirect wholly owned subsidiaries. Overview – Strategy and Results Seacoast Banking Corporation of Florida (“Seacoast” or the “Company”), a financial holding company, registered under the Bank Holding Company Act of 1956, as amended (the “BHC Act”), is one of the largest community banks in Florida, with $8.3 billion in assets and $6.9 billion in deposits as of December 31, 2020. Its principal subsidiary is Seacoast National Bank (“Seacoast Bank”), a wholly owned national banking association. The Company provides integrated financial services including commercial and retail banking, wealth management, and mortgage services to customers through advanced banking solutions, and Seacoast Bank's network of 51 traditional branches and commercial banking centers. Seacoast operates primarily in Florida, with concentrations in the state's fastest growing markets, each with unique characteristics and opportunities. The Company's offices stretch from the southeast, including Fort Lauderdale, Boca Raton and Palm Beach, north along the east coast to the Daytona area, into Orlando and Central Florida and the adjacent Tampa market, and west to Okeechobee and surrounding counties. The Company delivers integrated banking services, combining traditional retail locations with online and mobile technology and a convenient telephone banking center. Seacoast has built a fully integrated distribution platform across all channels to provide customers with the ability to choose their path of convenience to satisfy their banking needs, allowing the Company an opportunity to reach customers through a variety of sales channels. The Company believes its digital delivery and products are contributing to the franchise's growth. 30 Seacoast is executing a balanced growth strategy, combining organic growth with strategic acquisitions in Florida's most attractive growing markets. In Orlando, Seacoast is now the largest Florida-based bank and a top-10 bank in the Orlando market overall. In other key markets, including Palm Beach County, Fort Lauderdale, and Tampa, the Company has enhanced its footprint with ten acquisitions since 2014, generating continued expansion and strengthening market share, increasing the customer base and lowering operating costs through economies of scale. The Company's acquisition strategy has not only increased customer households and been accretive to earnings, but has also opened markets and Seacoast's customer base.

FBPB operated two branches, which were converted to Seacoast branches, with deposits of $174 million and loans of $147 million at the time of acquisition. In August 2020, Seacoast completed the acquisition of Fourth Street Banking Company (“Fourth Street”) and its wholly-owned subsidiary Freedom Bank, which added $303 million in loans and $330 million in deposits. The acquisition supports Seacoast’s growing presence in the attractive St. Petersburg, Florida market. Freedom Bank operated two branches in St. Petersburg, which were converted to Seacoast branches. Impact of COVID-19, the CARES Act and the Paycheck Protection Program on Comparability Among Periods Early in 2020, the global economy began experiencing a downturn resulting from the COVID-19 pandemic. Seacoast reacted quickly at the onset to make adjustments to operations intended to protect the health and welfare of our associates and customers. The Company's range of digital banking products combined with continued access to branches through drive-thrus and lobby appointments has allowed the Company to continue to meet customer needs. A robust and well-tested business continuity program has allowed the Company to maintain productivity levels with a majority of associates working remotely. The spread of COVID-19 has created a global public health crisis that has resulted in unprecedented uncertainty, volatility and disruption in financial markets and in governmental, commercial and consumer activity in the United States and globally, including the markets that we serve. Governmental responses to the pandemic have included orders to close businesses not deemed essential and directing individuals to restrict their movements, observe social distancing and shelter in place. These actions, together with responses to the pandemic by businesses and individuals, have resulted in rapid decreases in commercial and consumer activity, temporary, and some permanent, closures of many businesses that have led to a loss of revenues and a rapid increase in unemployment, material decreases in business valuations, disrupted global supply chains, market downturns and volatility, changes in consumer behavior related to pandemic fears (including a decline in demand for banking products or services, including loans and deposits which could impact our future financial condition, results of operations and liquidity), related emergency response legislation and an expectation that Federal Reserve policy will maintain a low interest rate environment for the foreseeable future. Although financial markets have rebounded from significant declines that occurred 31 earlier in the pandemic and global economic conditions showed signs of improvement beginning during the second quarter of 2020, many of the effects that arose or became more pronounced after the onset of the COVID-19 pandemic have persisted through the end of the year. These changes have had and are likely to continue to have a significant adverse effect on the markets in which we conduct our business and the demand for our products and services. Our business and consumer customers are experiencing varying degrees of financial distress, which is expected to continue into the first quarter of 2021 and beyond, especially if COVID-19 infections increase and new economic restrictions are mandated. Our borrowing base includes customers in industries such as hotel/lodging, restaurants, and retail, all of which have been and are likely to continue to be significantly impacted by the COVID-19 pandemic. We recognize that these industries may take longer to recover as consumers may be hesitant to return to full social interaction or may change their spending habits on a more permanent basis as a result of the pandemic. We continue to monitor these customers closely. Future economic conditions are subject to significant uncertainty. We have taken deliberate actions to ensure that we have the balance sheet strength to serve our clients and communities, including increases in liquidity and managing our assets and liabilities in order to maintain a strong capital position. Current economic pressures and their effects on our customers, coupled with the implementation of the CECL expected loss methodology for determining our allowance for credit losses, have contributed to a substantially increased provision for credit losses in 2020. We continue to monitor closely the impact of the COVID-19 pandemic on our customers, as well as the effects of the CARES Act. Uncertainties associated with the pandemic include the duration of the outbreak (including the impact of new variants of the virus that may be resistant to the various vaccines available), the impact to our customers, employees and vendors and the impact to the economy as a whole. COVID-19 has had, and is expected to continue to have, a significant adverse impact on our business, financial position and operating results. The extent to which the COVID-19 pandemic will impact our operations and financial results in 2021 cannot be fully estimated at this time. In March 2020, the Coronavirus Aid, Relief and Economic Security (“CARES”) Act was signed into law. The CARES Act includes provisions for the Paycheck Protection Program (“PPP”) offered through the U.S. Small Business Administration (“SBA”). Loans originated under this program have a contractual rate of interest of 1% with principal and interest that may be forgiven provided that the borrower uses the funds in a manner consistent with PPP guidelines. Seacoast assisted borrowers in 2020 with more than 5,500 loans originated through the PPP and, when combined with PPP loans acquired from Freedom Bank, outstanding balances totaled $567.0 million at December 31, 2020. The SBA established a fee structure based on loan size. Fees received by Seacoast, net of related costs, totaled $17.2 million, and are deferred and recognized as an adjustment to yield over time. Seacoast recognized net fees of $7.8 million and contractual interest of $4.2 million on PPP loans in 2020. The remaining $9.5 million in deferred PPP loan fees at December 31, 2020 will be recognized over the loans' remaining contractual maturity or sooner, as loans are forgiven. In January 2021, the Company began accepting applications for the re-opening of the PPP lending program on our fully digital origination platform. As of February 18, 2021, the Company had originated approximately 1,800 loans totaling $180 million under the latest round of PPP. Loan Modifications The CARES Act, as amended by the Consolidated Appropriations Act on December 27, 2020, provides financial institutions the option to exclude from troubled debt restructuring (“TDR”) consideration certain loan modifications that might otherwise be categorized as TDRs under ASC 310-40 in order to assist borrowers financially impacted by COVID-19. 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 financially affected by the pandemic should not be considered TDRs if the borrower was current at the time of modification. Seacoast began offering payment accommodations to eligible borrowers in March 2020 and, at December 31, 2020, $74.1 million of loans, or 1% of total loans, had active payment accommodations, down 93% from a peak of $1.1 billion in the second quarter of 2020. None of these loans have been classified as TDRs. During the payment accommodation period, Seacoast typically continues to recognize interest income. Adoption of New Accounting for Credit Losses On January 1, 2020, the Company adopted ASC Topic 326 - Financial Instruments - Credit Losses, which replaced the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The adoption resulted in an increase to the allowance for credit losses on loans of $21.2 million and an addition to the reserve for unfunded lending-related commitments of $1.8 million. 32 2020 Financial Performance Highlights • • • • • • • Steady build of shareholder value through consistent growth in tangible book value per share, which ended the period at $16.16, an increase of 15% during the fourth quarter on an annualized basis. The tangible common equity ratio of 11% supports Seacoast's ability to deploy capital for organic growth and opportunistic acquisitions. Record net income of $29.3 million in the fourth quarter, increasing 30% quarter-over-quarter. Record levels of mortgage banking fees and wealth management income in 2020, reflecting increases of 126% and 18%, respectively, from 2019. The successful acquisitions of First Bank of the Palm Beaches and Freedom Bank added experienced bankers while expanding the Company's presence in attractive growth markets, which we believe will further support sustainable, profitable growth. Total deposits per banking center were $135.9 million at December 31, 2020, an increase of 17% from $116.3 million one year earlier. Continued discipline around expenses, primarily achieved through focus on reducing overhead and streamlining business and cost savings processes, achieving a fourth quarter 2020 efficiency ratio below 50%. Results of Operations Earnings Summary For the year ended December 31, 2020, net income totaled $77.8 million, or $1.44 per diluted share, compared to $98.7 million, or $1.90 per diluted share, for the year ended December 31, 2019. Return on average assets (“ROA”) was 0.99% and return on average equity (“ROE”) was 7.44% in 2020 compared to 1.45% and 10.63%, respectively, in 2019. Adjusted net income1 for the year ended December 31, 2020 totaled $89.0 million, or $1.65 per diluted share, compared to $104.6 million, or $2.01 per diluted share, in 2019.

The change reflects the impact on net income of increased provisioning for credit losses in 2020 attributed to the adoption of CECL on January 1, 2020, and the financial impact of the COVID-19 pandemic, as well as growth in the balance sheet resulting from PPP loans, acquisitions, and higher deposit balances. In 2020, the Company's efficiency ratio, defined as noninterest expense less foreclosed property expense and amortization of intangibles divided by net operating revenue (net interest income on a fully tax equivalent basis plus noninterest income excluding securities gains and losses), was 54.84%, compared to 51.71% for 2019. Changes from the prior year reflect higher 2020 expenses, including acquisition-related costs, partially offset by lower funding costs and increases in noninterest income. The adjusted efficiency ratio1 in 2020 was 51.63% compared to 50.90% in 2019. The Company expects to maintain an adjusted efficiency ratio in the low 50s for the full year 2021. 33 Net Interest Income and Margin Net interest income for the year ended December 31, 2020 totaled $262.7 million, increasing $19.1 million, or 8%, compared to the year ended December 31, 2019. Net interest income (on a fully taxable equivalent basis)1 for the year ended December 31, 2020 was $263.2 million, increasing $19.3 million, or 8%, compared to the year ended December 31, 2019. In 2020 and 2019, net interest margin was 3.65% and 3.92%, respectively. In 2020, net interest income and the net interest margin reflect the impact of interest rate cuts by the Federal Reserve in the first quarter of 2020 in response to the COVID-19 pandemic. Loans and security yields contracted by 59 and 67 basis points, respectively, offset by a decline in the cost of deposits by 37 basis points. The impact on net interest margin from accretion of purchase discounts on acquired loans was 21 basis points in 2020, compared to 25 basis points in 2019. PPP loans decreased net interest margin by three basis points in 2020. Table 2 presents the Company’s average balance sheets, interest income and expenses, and yields and rates, for the past three years. The following table details the trend for net interest income and margin results (on a fully taxable equivalent basis)1, yield on earning assets and rate on interest bearing liabilities.

Average investment securities balances increased $99.6 million, or 8%, during 2020 compared to 2019. Average loans (the highest yielding component of earning assets) as a percentage of average earning assets totaled 79% in 2020 and 2019. The mix of loans has remained stable, with volumes related to commercial real estate representing 52% of total loans, excluding PPP loans, at December 31, 2020, compared to 49% at December 31, 2019. Residential loan balances with individuals (including home equity loans and lines and personal construction loans) represented 28% of total loans, excluding PPP loans, at December 31, 2020 compared to 32% at December 31, 2019.

During 2019, the Company acquired $72.4 million in fixed-rate commercial real estate loans from the wholesale market. No purchases were made in the wholesale market during 2020. Residential loan production totaled $638.6 million in 2020 compared to $523.6 million in 2019. 2019 includes purchases of residential loans from the wholesale market totaling $134.7 million. No purchases were made in the wholesale market during 2020. Consumer originations totaled $219.3 million during 2020 compared to $214.5 million during 2019. Seacoast originated more than 5,500 loans to borrowers through the PPP program for $599.0 million in 2020, and acquired $55.0 million in PPP loans from Freedom Bank. Under the terms of the SBA's program, principal and interest on PPP loans may be forgiven provided the borrower uses the funds in a manner consistent with the program's guidelines. As of December 31, 2020, $71.8 million in PPP loans had been forgiven. Average debt securities increased $99.6 million, or 8%, from 2019. Securities comprised 18% and 19% of average earning assets in 2020 and 2019, respectively. Yields on securities decreased from 3.00% in 2019 to 2.33% in 2020. In 2020, the cost of average interest-bearing liabilities decreased 57 basis points to 0.53% from 2019, reflecting the impact of interest rate reductions in 2019 and 2020. The low overall cost of our funding reflects the Company’s successful core deposit focus that produced strong growth in customer relationships over the past several years. Noninterest bearing demand deposits at December 31, 2020 represent 33% of total deposits, compared to 28% at December 31, 2019. The cost of average total deposits (including noninterest bearing demand deposits) in 2020 was 0.32%, compared to 0.69% in 2019. 35 The following table details the Company's customer relationship funding as of: (In thousands, except percentages) Noninterest demand Interest-bearing demand Money market Savings Time certificates of deposit Total deposits Customer sweep accounts Noninterest demand deposit mix $ $ $ December 31, 2020 2,289,787 1,566,069 1,556,370 689,179 831,156 6,932,561 119,609 $ $ $ 2019 1,590,493 1,181,732 1,108,363 519,152 1,185,013 5,584,753 86,121 33% 28% The Company’s focus on convenience, with high-quality customer service, expanded digital offerings and distribution channels provides stable, low-cost core deposit funding. Over the past several years, the Company has strengthened its retail deposit franchise using new strategies and product offerings, while maintaining a focus on growing customer relationships. Seacoast believes that digital product offerings are central to core deposit growth and have proved to be of meaningful value to its customers in this environment. Seacoast's call center and retail associates continue to lead the market in availability and customer service standards, with the call center out-performing large bank call center wait times and service level standards. The impact of PPP originations and individual stimulus payments, as well as the acquisition of FBPB in the first quarter of 2020 and Freedom Bank in the third quarter of 2020, have all contributed to higher deposit balances. The Company has also seen a continued shift toward mobile banking use as customers recognize the ease of access and security features of such engagement. At December 31, 2020, registered mobile devices had increased 16% compared to December 31, 2019, while online users increased 13% in the same time period. Growth in mobile banking use represents both consumer and business customers utilizing the convenience of mobile and online channels. During 2020, average transaction deposits (noninterest and interest bearing demand) increased $676.3 million, or 25%, compared to 2019. Along with new relationships, deposit programs and digital sales have improved the Company's market share and deepened relationships with existing customers. Growth in core deposits has also provided low funding costs. The Company’s deposit mix remains favorable, with 83% of average deposit balances comprised of savings, money market, and demand deposits in 2020. Sweep repurchase agreements with customers increased $33.5 million, or 39%, to $119.6 million at December 31, 2020 compared to $86.1 million at December 31, 2019. The average rate on customer repurchase accounts was 0.33% in 2020 compared to 1.35% in 2019. No federal funds purchased were utilized at December 31, 2020 or 2019. The Company had no FHLB borrowings outstanding at December 31, 2020 compared to $315.0 million at December 31, 2019. FHLB borrowings averaged $139.4 million at an average rate of 1.10% for the full year 2020, compared to $131.9 million at an average rate of 2.28% for the full year 2019 (see “Note J - Borrowings” to the Company’s consolidated financial statements). In 2020, average subordinated debt of $71.2 million related to trust preferred securities issued by subsidiary trusts of the Company carried an average cost of 3.07%, down from 4.75% in 2019, reflecting the impact of lower interest rates as the subordinated debt cost is based on LIBOR plus a spread (see “Note J - Borrowings”). Provision for Credit Losses The provision for credit losses was $38.2 million for the full year 2020 compared to $11.0 million for the full year 2019. On January 1, 2020, the Company adopted ASC Topic 326 - Financial Instruments - Credit Losses. Under the CECL approach, the Company reserves for the full amount of expected credit losses over the life of the loans. The estimate is based on current conditions and reasonable and supportable forecasts. This use of CECL requires earlier recognition, when compared with the previous accounting guidance, of credit losses that are deemed expected but not yet probable. The expectation of higher future losses due to the ongoing impact of COVID-19 on the current and forecasted economic environment resulted in the increase in provisioning during 2020. 36 Noninterest Income Noninterest income (excluding securities gains and losses) totaled $60.3 million in 2020, an increase of $4.8 million, or 9%, compared to 2019. Noninterest income accounted for 19% of total revenue in 2020 and 2019 (net interest income plus noninterest income, excluding securities gains and losses). Service charges on deposits for the year ended December 31, 2020 compared to the year ended December 31, 2019 decreased $2.1 million, or 18%, to $9.4 million. This decrease reflects the impact of the COVID-19 pandemic on service charges, including the waiver of certain account charges during the second quarter of 2020, as well as higher average deposit balances resulting in lower overdraft fees in 2020. Overdraft fees represented 44% of total service charges on deposits in 2020 compared to 55% in 2019. Interchange revenue totaled $13.7 million in 2020, an increase of 2% from $13.4 million in 2019. Growth in business customers and marketing targeted at increasing debit card utilization across all customers resulted in record interchange revenue for the year. Wealth management revenues, including brokerage commissions and fees and trust income, increased $1.2 million, or 18%, to $7.5 million for the year ended December 31, 2020. A determined and consistent focus on building new relationships and providing exceptional services resulted in considerable growth during 2020, with assets under management (“AUM”) increasing 33% year-over-year to $870 million as of December 31, 2020. Mortgage banking fees increased by $8.2 million, or 126%, to $14.7 million for the year ended December 31, 2020 compared to 2019. In 2020, Seacoast continued to capitalize on the robust residential refinance market and a vibrant Florida housing market, resulting in record results for the year. Marine finance fees were $0.7 million in 2020, a decrease of $0.4 million, or 34%, compared to fees of $1.1 million in 2019. Gains on sale of the guaranteed portion of SBA loans totaled $0.7 million for the year ended December 31, 2020, a decrease of $1.8 million compared to 2019. A shift toward PPP production beginning in the second quarter of 2020 in response to the COVID-19 pandemic resulted in lower production of saleable SBA loans for 2020. Bank owned life insurance (“BOLI”) income totaled $3.6 million in 2020, a decrease of $0.1 million, or 3%, compared to the prior year. Other income decreased $0.5 million, or 5%, year-over-year. 2020 results reflect higher swap fees, which are more than offset by a $1.0 million BOLI death benefit recognized in 2019. Securities gains in 2020 totaled $1.2 million, resulting from the sale of $96.7 million of debt securities, and a $0.1 million increase in the value of the CRA-qualified mutual fund investment. Securities gains in 2019 totaled $1.2 million, resulting from the sale of $202.7 million of debt securities, and a $0.2 million increase in the value of the CRA-qualified mutual fund investment. Noninterest Expense The Company has demonstrated its commitment to efficiency through disciplined, proactive management of its cost structure. Noninterest expenses in 2020 totaled $185.6 million and included acquisition-related expenses of $9.1 million, expenses related to branch consolidation of $0.8 million, and $0.3 million in bonuses to retail associates for keeping critical functions operating at full capacity through the initial stages of the Company's response to the COVID-19 pandemic. In 2019, noninterest expenses totaled $160.7 million, including $1.0 million in acquisition-related expenses, $1.8 million in expenses related to branch consolidation, and $0.1 million in business continuity expenses relating to a hurricane event. Adjusted noninterest expense1 in 2020 totaled $169.5 million, an increase of 12% from 2019, reflecting overall growth of the organization. Changes in the categories of noninterest expense for the year ended 2020 compared to 2019 are further described below. Seacoast has expanded its footprint while decreasing its reliance on branches through successful bank acquisitions and the repositioning of the banking center network in strategic growth markets to meet the evolving needs of its customers. At December 31, 2020, deposits per banking center were $135.9 million, up 17% from $116.3 million at December 31, 2019. The Company consolidated one banking center location in 2020 and three in 2019. The Company plans to further consolidate three banking center locations in the first quarter of 2021. Salaries and wages totaled $88.5 million in 2020, an increase of $14.7 million, or 20%, compared to 2019. Results in 2020 include $2.8 million in bank acquisition-related charges. Record levels of saleable mortgage production resulted in higher 37 commissions, and bonuses were paid to retail associates for keeping critical functions operating at full capacity through the initial stages of the Company's response to the COVID-19 pandemic. Higher headcount is attributed to the recruitment of seasoned bankers in key markets, to the FBPB and Freedom Bank acquisitions, and the addition of staff to support the PPP. Higher loan originations in 2020 relating to the PPP resulted in higher deferrals of related salary costs. During 2020, employee benefit costs, which include group health insurance, 401(k) plan contributions, payroll taxes, and unemployment compensation, increased $1.8 million, or 13%, compared to 2019. The increase is attributed to higher headcount and higher health insurance costs. The Company utilizes third parties for core data processing systems. The data processing costs associated with these third parties fluctuate based on the number of transactions processed and the negotiated rates associated with those transactions. Outsourced data processing costs totaled $19.1 million and $15.1 million in 2020 and 2019, respectively. Of the $4.0 million, or 26%, increase in 2020, $2.7 million is the result of acquisition-related costs incurred in 2020. The Company continues to improve and enhance mobile and other digital products and services through key third parties. Outsourced data processing costs may increase in the future as customers adopt improved products and as business volumes grow. Telephone and data line expenses, including electronic communications with customers, between branch locations and personnel, and with third party data processors, remained flat year-over-year at $3.0 million. The Company continues to manage expenses for this category, which has benefited from branch consolidation, while continuing to grow alternative service channels including the Customer Support Center and digital applications. Total occupancy, furniture and equipment expenses in 2020 totaled $20.0 million, a decrease of $0.5 million, or 2%, compared to 2019. The decrease reflects the benefit of recent branch consolidations. The Company continues to strategically manage its branch footprint to balance customer needs for access to physical branches with the ability to provide services through telephone-based and digital channels. Branch consolidations will continue for the Company and the banking industry in general as the customer service dynamic continues to evolve. In 2020 and 2019, marketing expenses totaled $4.8 million and $4.2 million, respectively. The Company continues to carefully manage the use of marketing campaigns to target potential high value customers in a cost effective manner through a mix of digital communications, direct mail, event sponsorships and donations. Legal and professional fees increased by $0.6 million in 2020, or 7%, to $9.2 million, which includes $2.7 million in merger- related expenses in 2020, compared to $0.4 million in 2019. FDIC assessments were $1.3 million in 2020, compared to $0.9 million in 2019. In the third quarter of 2019, the FDIC announced the achievement of the target deposit insurance reserve ratio, resulting in the Company's ability to apply previously awarded credits to its deposit insurance assessment. The Company used these credits to offset $0.9 million of expenses during 2019 and $0.7 million during 2020. The credits were fully utilized by the second quarter of 2020. For the year ended December 31, 2020, foreclosed property expense and net loss on sale was $2.3 million, compared to $0.1 million in 2019. Results in 2020 primarily reflect the write-downs of two properties in the fourth quarter upon the receipt of updated valuations. Other expense totaled $15.8 million and $15.2 million in 2020 and 2019, respectively. The increase of $0.6 million, or 4%, includes higher recruiting fees and higher mortgage production-related expenses. Income Taxes In 2020, the provision for income taxes totaled $22.8 million, compared to $29.9 million in 2019. In 2019, a reduction in the State of Florida corporate income tax rate resulted in the write-down of certain deferred tax assets, resulting in additional income tax expense of $1.1 million. In 2020, changes under the CARES Act provided for the carryback of net operating losses that resulted in an income tax benefit of $0.4 million. Discrete tax benefits related to share-based compensation were $0.1 million and $0.8 million in 2020 and 2019, respectively. Fourth Quarter Review Net income totaled $29.3 million in the fourth quarter of 2020, an increase of $6.7 million, or 30%, from the third quarter of 2020, and an increase of $2.2 million, or 8%, compared to the fourth quarter of 2019. Adjusted net income1 totaled $30.7 million, an increase of $3.4 million, or 12%, from the third quarter of 2020, and an increase of $3.9 million, or 14%, compared 38 to the fourth quarter of 2019. Diluted earnings per common share (“EPS”) was $0.53 and adjusted diluted EPS12was $0.55 in the fourth quarter of 2020, compared to diluted EPS of $0.42 and adjusted diluted EPS1 of $0.50 in the third quarter of 2020 and compared to diluted EPS of $0.52 and adjusted diluted EPS1 of $0.52 in the fourth quarter of 2019. Revenues increased $3.3 million, or 4%, from the third quarter of 2020 and increased $5.6 million, or 7%, from the fourth quarter of 2019. Net interest income increased $5.3 million, or 8%, compared to the third quarter of 2020 and increased $7.0 million, or 11%, compared to the fourth quarter of 2019. Net interest income (on a tax-equivalent basis), for the fourth quarter of 2020 totaled $68.9 million, an increase of $5.3 million, or 8%, from the third quarter of 2020, and an increase of $7.1 million, or 11%, from the fourth quarter 2019. Net interest margin (on a tax-equivalent basis), increased 19 basis points to 3.59% from the third quarter of 2020, and contracted 25 basis points from the fourth quarter of 2019. During the fourth quarter of 2020, net interest income included $5.2 million in interest and fees earned on PPP loans compared to $1.7 million in the third quarter of 2020. Lower PPP loan fees in the third quarter resulted from a calculation change to align fee recognition with the contractual maturity of the loans. Loan forgiveness began in the fourth quarter of 2020, resulting in accelerated recognition of $1.5 million in PPP loan fees. Noninterest income, excluding securities gains and losses, totaled $14.9 million for the fourth quarter of 2020, a decrease of $2.0 million, or 12%, from the third quarter of 2020 and an increase of $1.1 million, or 8%, from the fourth quarter of 2019. Mortgage banking gains decreased by $1.6 million to $3.6 million in the fourth quarter of 2020, compared to record results in the prior quarter. The low interest rate environment continued to result in heightened refinance demand, though at lower levels than in the third quarter. Noninterest expenses for the fourth quarter of 2020 totaled $43.7 million, a decrease of $8.0 million, or 15% from the prior quarter and an increase of $5.6 million, or 15%, from the fourth quarter of 2019. Compared to the third quarter of 2020, salaries and wages decreased by $1.6 million to $21.5 million, primarily reflecting the effect of higher expense deferrals associated with accelerated commercial loan originations in the fourth quarter. Other decreases compared to the third quarter of 2020 are primarily attributed to merger-related expenses. A provision for loan losses of $1.9 million was recorded in the fourth quarter of 2020 compared to a reversal of $0.8 million in the previous quarter. The ratio of allowance for credit losses to total loans was 1.62% at December 31, 2020, compared to 1.60% at September 30, 2020. Excluding PPP loans, the ratio was 1.79% at December 31, 2020, compared to 1.80% at September 30, 2020. 12Non-GAAP measure, see “Explanation of Certain Unaudited Non-GAAP Financial Measures” for more information and a reconciliation to GAAP. 39 Explanation of Certain Unaudited Non-GAAP Financial Measures This report 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, fully taxable equivalent net interest income, noninterest income, noninterest expense, tax adjustments, net interest margin 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.

Securities Information related to yields, maturities, carrying values and fair value of the Company’s securities is set forth in Tables 13-16 and “Note D - Securities” of the Company’s consolidated financial statements. At December 31, 2020, the Company had $1.4 billion in securities available-for-sale, and $184.5 million in securities held-to- maturity. The Company's total debt securities portfolio increased $374.4 million, or 31% from December 31, 2019. During the year ended December 31, 2020, there were $830.3 million of debt security purchases and $379.9 million in paydowns and maturities over the same period. For the year ended December 31, 2020, proceeds from the sale of securities totaled $96.7 million, with net gains of $1.1 million. During the year ended December 31, 2019, there were $309.5 million of debt security purchases and $144.2 million in paydowns and maturities over the same period. For the year ended December 31, 2019, proceeds from the sale of securities totaled $202.7 million, with net losses of $1.0 million. Debt securities generally return principal and interest monthly. The modified duration of the investment portfolio at December 31, 2020 was 3.8 years, compared to 3.5 years at December 31, 2019. At December 31, 2020, available-for-sale securities had gross unrealized losses of $2.1 million and gross unrealized gains of $28.7 million, compared to gross unrealized losses of $2.7 million and gross unrealized gains of $8.8 million at December 31, 2019. The Company assesses securities in an unrealized loss position on a quarterly basis. As of December 31, 2020, the Company expected to recover the entire amortized cost basis of these securities and therefore no allowance for credit losses was recorded. The credit quality of the Company’s securities holdings are primarily investment grade. As of December 31, 2020, the Company’s investment securities, except for $35.3 million of securities issued by states and their political subdivisions, generally are traded in liquid markets. U.S. Treasury and U.S. government agencies and obligations of U.S. government- sponsored entities totaled $1.3 billion, or 79%, of the total portfolio. The portfolio also includes $91.2 million in private label securities, most secured by residential real estate collateral, with low loan to values and average credit support of 22%. The Company also has invested $202.2 million in uncapped 3-month LIBOR floating rate collateralized loan obligations. Collateralized loan obligations are special purpose vehicles that purchase first lien broadly syndicated corporate loans while providing support to senior tranche investors. As of December 31, 2020, all of the Company's collateralized loan obligations were in AAA/AA tranches with average credit support of 30%. The Company performs routine stress testing on these securities to assess both structure and collateral. Loan Portfolio Loans, net of unearned income and excluding the allowance for credit losses, were $5.6 billion at December 31, 2020, an increase of $479.4 million, or 9%, compared to December 31, 2019. In the second quarter of 2020, the Company began originating Paycheck Protection Program (“PPP”) loans established by the Coronavirus Aid, Relief and Economic Security (“CARES”) Act. At December 31, 2020, the Company had $567 million in PPP loans outstanding. Excluding PPP loans, loans outstanding decreased year-over-year by $30 million to $5.2 billion. The Company adhered to its conservative underwriting guidelines through 2020 in response to the impact of the COVID-19 pandemic on the economic environment. For the year ended December 31, 2020, non-PPP commercial loan originations, including small business and SBA loans, were $655.8 million, compared to $1.1 billion for the year ended December 31, 2019, a decrease of 38%. The loan pipeline for commercial loans totaled $166.7 million at December 31, 2020. Residential loans originated for sale in the secondary market were $509.4 million for the year ended December 31, 2020, compared to $236.5 million for the year ended December 31, 2019. A vibrant refinance market and a strong Florida housing market, combined with the residential lending team's focus on high-quality service levels to homebuyers, refinance customers and local real estate professionals, resulted in record originations for the year. Originations of residential loans retained were $129.2 million in 2020, compared to $287.0 million in December 31, 2019. The saleable residential mortgage pipeline at December 31, 2020 totaled $92.0 million while the retained pipeline was $25.1 million. During 2020, the Company successfully completed two bank acquisitions, resulting in loans acquired of $146.8 million in the FBPB acquisition and $303.4 million in the Freedom Bank acquisition. 45 During 2019, the Company purchased $201.1 million in loans, with an average loan size of $297 thousand and an average yield of 3.92%. The Company made no loan purchases during 2020. The Company has maintained a conservative approach to underwriting and has intentionally slowed loan growth since the onset of the pandemic in light of increased economic uncertainty. Assuming the economic recovery commences in the second half of 2021, the resumption of growth will be accompanied by defined risk management procedures. Lending policies contain guardrails that pertain to lending by type of collateral and purpose, along with limits regarding loan concentrations and the principal amount of loans. The Company's exposure to commercial real estate lending remains below regulatory limits (see “Loan Concentrations”). The following table details loan portfolio composition at December 31, 2020 for portfolio loans, purchased credit deteriorated loans (“PCD”) and loans purchased which are not considered credit deteriorated (“Non-PCD”) as defined in “Note E - Loans”; and at December 31, 2019 for portfolio loans, purchased unimpaired loans (“PUL”) and purchased credit impaired loans (“PCI”). With the adoption of ASC Topic 326 - Financial Instruments - Credit Losses on January 1, 2020, the Company re- evaluated the aggregation of loans into segments, and separated Commercial Real Estate - Owner Occupied from Commercial Real Estate - Non Owner Occupied. In prior years, all Commercial Real Estate loans were considered a single segment.

Commercial real estate loans, inclusive of owner-occupied commercial real estate, increased $158.2 million, or 7%, totaling $2.5 billion at December 31, 2020, compared to December 31, 2019. Owner-occupied loans represent $1.1 billion, or 45%, of the commercial real estate portfolio. Office building loans of $761.1 million, or 27%, of commercial real estate mortgages, comprise our largest concentration with a substantial portion owner-occupied. Fixed-rate and adjustable-rate loans secured by commercial real estate, excluding construction loans, totaled approximately $2.1 billion and $453.7 million, respectively, at December 31, 2020, compared to $2.0 billion and $418.8 million, respectively, at December 31, 2019. At December 31, 2020, Seacoast had $74.1 million of loans with payment accommodations to borrowers financially impacted by the COVID-19 pandemic, none of which have been classified as a TDR. If economic conditions deteriorate further, these borrowers may be unable to resume scheduled payments, which may result in reversal of accrued interest, further modification of terms and additional necessary provisions for credit losses. At December 31, 2020, of loans that were provided with payment assistance during 2020, 94% are in current status or have paid off the balance entirely, less than 1% are 30 or more days past due, and 5% have been provided with an additional accommodation, including additional payment deferrals or interest only payment arrangements. Interest and fees have typically continued to accrue on these loans throughout their accommodation period. 46 The following table presents loans with accommodations, excluding PPP loans, at December 31, 2020: (In thousands) Loans with Payment Accommodations Total Loans including Loans with Payment Accommodations % of Loans with Payment Accommodations Construction and land development $ 1,032 $ Commercial real estate - owner-occupied Commercial real estate - non owner-occupied Residential real estate Commercial and financial Consumer Totals 14,248 32,549 12,839 11,915 1,479 $ 74,062 $ 245,108 1,141,310 1,395,854 1,342,628 854,753 188,735 5,168,388 — % 1 2 1 1 1 1% The following table details commercial real estate and construction and land development loans outstanding by collateral type at December 31, 2020: ($ in thousands) Office Building Retail Industrial & Warehouse Other Commercial Property Healthcare Apartment Building / Condominium Hotel / Motel Vacant Lot Convenience Store Restaurant 1-4 Family Residence - Individual Borrowers Church School/ Education 1-4 Family Residence - Spec Home Agriculture Manufacturing Building 1-4 Family Residence - Builder Lines Recreational Property Other Properties Total OOCRE, CRE & ADC $ 761,118 454,863 385,875 261,875 219,736 171,141 130,743 75,480 56,474 49,636 48,472 29,155 28,133 23,846 19,832 18,106 16,280 14,976 16,531 % of Total Loans 13% With Payment Accommodations 6,416 $ 8 7 5 4 3 2 1 1 1 1 1 — — — — — — — 4,505 661 2,688 777 555 25,169 66 734 5,691 301 266 — — — — — — — $ 2,782,272 49% $ 47,829 The largest collateral type in the CRE and construction portfolios, when aggregated, is office buildings, representing 13% of the portfolio.

This primarily includes medical, accounting, engineering, health care, veterinarians and other similar professionals. The second-largest category is retail, representing 8% of total loans. The average loan size in the retail category is $1.3 million and the average LTV is 58%. Loans collateralized by hotels/motels represent $130.7 million with an average loan size of $2.9 million and an average LTV of 54%. Restaurant exposure is limited at $49.6 million in loans, and is distributed among quick serve and full-service restaurants, with an average loan size of $788 thousand and LTV of 57%. 47 The following table details the commercial and financial loans outstanding by industry type at December 31, 2020: % of Total Loans With Payment Accommodations — $ 4% ($ in thousands) Management Companies1 Professional, Scientific, Technical & Other Services Commercial and Financial $ 202,442 101,661 Real Estate Rental & Leasing Healthcare & Social Assistance Finance & Insurance Construction Manufacturing Transportation & Warehousing Wholesale Trade Retail Trade Education Accommodation & Food Services Administrative Support Public Administration Agriculture Other Industries 79,759 74,158 72,771 67,098 52,700 46,803 36,969 24,896 22,204 16,830 13,675 12,056 11,151 19,580 2 1 1 1 1 1 1 1 — — — — — — — 991 241 403 — 972 1,777 5,786 — 951 — 351 89 — 8 346 11,915 Total 1Primarily corporate aircraft and marine vessels associated with high net worth individuals. $ 854,753 14% $ Commercial and financial loans outstanding increased $76.5 million, or 10%, year-over year to $854.8 million as of December 31, 2020. The Company's primary customers for commercial and financial loans are small- to medium-sized professional firms, retail and wholesale outlets, and light industrial and manufacturing companies. Such businesses are smaller and subject to the risks of lending to small- to medium-sized businesses, including, but not limited to, the effects of a downturn in the local economy, possible business failure, and insufficient cash flows. Residential mortgage loans decreased $165.2 million, or 11%, year-over-year to $1.3 billion as of December 31, 2020. Substantially all residential originations have been underwritten to conventional loan agency standards, including loans having balances that exceed agency value limitations. At December 31, 2020, approximately $436.3 million, or 32%, of the Company’s residential mortgage balances were adjustable 1-4 family mortgage loans (including hybrid adjustable rate mortgages). Fixed rate mortgages totaled $499.0 million, or 37%, of the residential mortgage portfolio at December 31, 2020, of which 15- and 30-year mortgages totaled $38.4 million and $362.9 million, respectively. Remaining fixed rate balances were comprised of home improvement loans totaling $163.5 million, most with maturities of 10 years or less. Home equity lines of credit, primarily floating rates, totaled $341.6 million at December 31, 2020. In comparison, fixed-rate loans secured by residential properties totaled $590.0 million at December 31, 2019, with 15- and 30-year fixed-rate residential mortgages totaling $43.5 million and $372.0 million, respectively, and home equity mortgages and lines of credit totaled $243.8 million and $292.1 million, respectively. The Company also provides consumer loans, which includes installment loans, auto loans, marine loans and other consumer loans, which decreased $19.5 million, or 9%, year-over-year to a total of $188.7 million at December 31, 2020, compared to $208.2 million at December 31, 2019. Of the $19.5 million decrease, automobile loans and other consumer loans decreased $20.6 million and $5.3 million, respectively, while marine loans increased $6.4 million. At December 31, 2020, the Company had unfunded commitments to make loans of $1.5 billion, compared to $1.0 billion at December 31, 2019 (see “Note Q - Contingent Liabilities and Commitments with Off-Balance Sheet Risk” to the Company’s consolidated financial statements). 48 Loan Concentrations The Company has developed guardrails to manage loan types that are most impacted by stressed market conditions in order to achieve lower levels of credit loss volatility in the future. Outstanding balances for commercial and commercial real estate (“CRE”) loan relationships greater than $10 million totaled $753.7 million, representing 13% of the total portfolio, at December 31, 2020, compared to $680.2 million, or 13%, at December 31, 2019. The Company’s ten largest commercial and commercial real estate funded and unfunded loan relationships at December 31, 2020 aggregated to $254.3 million, of which $188.0 million was funded, compared to $268.9 million at December 31, 2019, of which $179.0 million was funded. The Company had 135 commercial and commercial real estate relationships in excess of $5 million totaling $1.3 billion, of which $1.2 billion was funded at December 31, 2020, compared to 120 relationships totaling $1.2 billion at December 31, 2019, of which $1.0 billion was funded. Concentrations in total construction and land development loans and total CRE loans are maintained well below regulatory limits. Construction and land development and CRE loan concentrations as a percentage of total risk based capital, declined to 26% and 169%, respectively, at December 31, 2020, compared to 40% and 204% as of December 31, 2019. Regulatory guidance suggests limits of 100% and 300%, respectively. On a consolidated basis, construction and land development and commercial real estate loans represent 24% and 157%, respectively, of total consolidated risk based capital. To determine these ratios, the Company defines CRE in accordance with the guidance on “Concentrations in Commercial Real Estate Lending” issued by the federal bank regulatory agencies in 2006 (and reinforced in 2015), which defines CRE loans as exposures secured by land development and construction, including 1-4 family residential construction, multifamily property, and non-farm nonresidential property where the primary or a significant source of repayment is derived from rental income associated with the property (i.e. loans for which 50 percent or more of the source of repayment comes from third party, non-affiliated, rental income) or the proceeds of the sale, refinancing, or permanent financing of the property. Loans on owner occupied CRE are generally excluded. Nonperforming Loans, Troubled Debt Restructurings, Other Real Estate Owned, and Credit Quality Table 12 provides certain information concerning nonperforming assets for the years indicated. Nonperforming assets (“NPAs”) at December 31, 2020 totaled $48.9 million, an increase of $9.5 million, or 24%, compared to 2019, and were comprised of $36.1 million of nonaccrual loans, $10.2 million of other real estate owned (“OREO”) and $2.6 million of branches taken out of service. Compared to December 31, 2019, nonaccrual loans increased by $9.2 million, or 34%, and non-branch OREO decreased $4.3 million, or 62%, the result of property sales. Approximately 80% of nonaccrual loans were secured with real estate at December 31, 2020. Nonaccrual loans have been written down by approximately $8.4 million, or 12%, of the original loan balance (including specific impairment reserves). See the tables below for details about nonaccrual loans. Nonperforming loans to total loans outstanding at December 31, 2020 increased to 0.63% from 0.52% at December 31, 2019. Nonperforming assets to total assets at December 31, 2020 increased to 0.59% from 0.55% at December 31, 2019. The Company’s asset mitigation staff handles all foreclosure actions together with outside legal counsel. Beginning in March 2020, in response to the economic downturn resulting from the COVID-19 pandemic, the Company has offered payment accommodations to affected borrowers. As of December 31, 2020, pandemic-related accommodations totaled $74.1 million and are not considered troubled debt restructurings (“TDRs”). If economic conditions deteriorate further, these borrowers may be unable to resume scheduled payments, which may result in further modification of terms and the potential for classification as a TDR in future periods. In addition to pandemic-related accommodations, the Company pursues loan restructurings in selected cases where it expects to realize better values than may be expected through traditional collection activities. The Company has worked with retail mortgage customers, when possible, to achieve lower payment structures in an effort to avoid foreclosure. TDRs have been a part of the Company’s loss mitigation activities and can include rate reductions, payment extensions and principal deferrals. Company policy requires TDRs that are classified as nonaccrual loans after restructuring remain on nonaccrual until performance can be verified, which usually requires six months of performance under the restructured loan terms. Accruing restructured loans totaled $4.2 million at December 31, 2020, compared to $11.1 million at December 31, 2019. Accruing TDRs are excluded from nonperforming asset ratios. The tables below set forth details related to nonaccrual and accruing restructured loans. 49 (In thousands) Construction & land development Residential Commercial Individuals Residential real estate mortgages Commercial real estate mortgages - owner occupied Commercial real estate mortgages - non-owner occupied Real estate loans Commercial and financial Consumer Total loans (In thousands) Construction & land development Residential Commercial Individuals Residential real estate mortgages Commercial real estate mortgages Real estate loans Commercial and financial Consumer Total loans December 31, 2020 Nonaccrual Loans Non-Current Current Total Accruing Restructured Loans $ — $ — $ — $ — 37 37 4,074 5,682 2,030 11,823 3,777 543 101 28 129 8,418 2,500 6,053 17,100 2,827 40 101 65 166 12,492 8,182 8,083 28,923 6,604 583 109 — — 109 3,740 109 — 3,958 — 224 $ 16,143 $ 19,967 $ 36,110 $ 4,182 December 31, 2019 Nonaccrual Loans Non-Current Current Total Accruing Restructured Loans $ — $ — $ — $ 4,902 — 4,902 2,552 3,802 11,256 4,674 38 15,968 $ $ — 35 35 6,927 2,718 9,680 1,235 72 10,987 $ 4,902 35 4,937 9,479 6,520 20,936 5,909 110 26,955 $ — — 131 131 6,027 4,666 10,824 26 250 11,100 At December 31, 2020 and December 31, 2019, total TDRs (performing and nonperforming) were comprised of the following loans by type of modification: (Dollars in thousands) Maturity extended Rate reduction Chapter 7 bankruptcies Not elsewhere classified Total loans December 31, 2020 December 31, 2019 Number Amount Number Amount 51 $ 37 13 5 5,438 4,275 417 160 42 $ 52 18 8 3,781 12,048 1,920 620 106 $ 10,290 120 $ 18,369 During the year ended December 31, 2020, ten loans totaling $0.7 million were modified to a TDR, compared to nine loans totaling $4.7 million for the year ended December 31, 2019. 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. There were no defaults on loans that had been 50 modified in TDRs within the twelve months preceding December 31, 2020 and four defaults totaling $3.2 million within the twelve months preceding December 31, 2019. A restructured loan is considered in default when it becomes 90 days or more past due under the modified terms, has been transferred to nonaccrual status, or has been transferred to OREO. In accordance with regulatory reporting requirements, loans are placed on nonaccrual following the Retail Classification of Loan interagency guidance. The accrual of interest is generally discontinued on loans, except consumer loans, that become 90 days past due as to principal or interest unless collection of both principal and interest is assured by way of collateralization, guarantees or other security. Consumer loans that become 120 days past due are generally charged off. The loan carrying value is analyzed and any changes are appropriately made as described above quarterly. Allowance for Credit Losses on Loans On January 1, 2020, the Company adopted ASC Topic 326 - Financial Instruments - Credit Losses. The new guidance replaced the incurred loss model with an expected loss model, which is referred to as the current expected credit loss (“CECL”) model. The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposure such as loan commitments, standby letters of credit, financial guarantees and other similar instruments. Management estimates the allowance using relevant available information, from both internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit losses provide the basis for 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 environmental conditions, such as changes in unemployment rates, property values, occupancy rates, and other macroeconomic metrics. Upon adoption of the new model, the initial adjustment to the allowance for credit losses was an increase of $21.2 million, bringing the ratio of allowance to total loans from 0.68% at December 31, 2019 to 1.08% at January 1, 2020. The increase was attributed to the new requirement to estimate losses over the full remaining expected life of the loans and to the impact of the new guidance on the Company's acquired loan portfolio. The economic forecast scenario as of January 1, 2020 projected a stable macroeconomic environment over the three year forecast period. In addition to the $21.2 million impact of the initial adoption of ASC Topic 326, increases in the allowance during 2020 reflected the deterioration of the current and forecasted macroeconomic environment with the onset and continuation of the COVID-19 pandemic. No allowance has been assigned to PPP loans, which are guaranteed by the U.S. government. Net charge-offs for 2020 were $7.6 million, or 0.14% of average loans, excluding PPP loans, compared to $8.1 million, or 0.16%, for 2019. Excluding PPP loans, the ratio of allowance to total loans increased to 1.79% at December 31, 2020 from 0.68% at December 31, 2019 and 1.08% at January 1, 2020. Uncertainty related to market conditions and the economic outlook will likely continue as the ongoing effects of the pandemic and the impact of additional government assistance programs remain unknown. Activity in the allowance for credit losses is summarized as follows: December 31, 2020 (In thousands) Beginning Balance Impact of Adoption of ASC 326 Initial Allowance on PCD Loans Acquired During the Period Provision for Credit Losses1 Charge- Offs Recoveries TDR Allowance Adjustments Ending Balance Construction and land development $ 1,842 $ 1,479 $ 87 $ 1,399 $ — $ 114 $ (1) $ 4,920 Commercial real estate - owner- occupied Commercial real estate - non owner- occupied Residential real estate Commercial and financial Consumer Paycheck Protection Program 5,361 80 1,161 3,632 (310) 7,863 9,341 2,236 18,966 (177) 7,667 9,716 2,705 — 5,787 3,677 862 — 124 2,643 28 — 3,840 8,329 1,613 — (240) (7,091) (2,024) — 18 37 350 1,416 316 — (74) 9,868 — 38,266 (28) — (11) — 17,500 18,690 3,489 — Totals $ 35,154 $ 21,226 $ 6,279 $ 37,779 $ (9,842) $ 2,251 $ (114) $ 92,733 1Excludes $0.4 million provision for credit losses on accrued interest receivable 51 Concentrations of credit risk, discussed under the caption “Loan Portfolio” of this discussion and analysis, can affect the level of the allowance and may involve loans to one borrower, an affiliated group of borrowers, borrowers engaged in or dependent upon the same industry, or a group of borrowers whose loans are predicated on the same type of collateral. At December 31, 2020, the Company's largest concentrations of credit risk were $2.5 billion in loans secured by commercial real estate and $1.3 billion in loans secured by residential real estate, representing 45% and 23% of total loans outstanding, respectively. In addition, the Company is subject to a geographic concentration of credit because it primarily operates in Florida. With the emergence of the COVID-19 pandemic in 2020 leading to significant market changes, high levels of unemployment and increasing degrees of uncertainty in the U.S. economy, the impact on expected losses on loans is difficult to estimate with precision, and it is possible that additional provisions for credit losses could be needed in future periods. LIBOR Transition The Company, along with the entire financial services industry, is preparing for the expected phase-out of the benchmark London Interbank Offered Rate (“LIBOR”). In preparing for the transition from LIBOR, the Company has formed a LIBOR transition steering committee which is responsible for overseeing the execution of the Company's enterprise-wide LIBOR transition program, and for evaluating and mitigating the risks associated with the transition from LIBOR. The LIBOR transition program includes a comprehensive review of the financial products, agreements, contracts and business processes that may use LIBOR as a reference rate, and the development and execution of a strategy to transition away from LIBOR, with appropriate consideration of the potential financial, customer, counterparty, regulatory and legal impacts. As of December 31, 2020, the Company has identified approximately $400 million in loans for which the repricing index is tied to LIBOR. The Company also invests in securities and has issued subordinated debt tied to LIBOR. The Company’s back-to- back swap agreements with customers and other derivatives are governed by the International Swap Dealers Association (“ISDA”). ISDA has developed fallback language for swap agreements and has established a protocol to allow counterparties to modify legacy trades to include the new fallback language. The Company continues to monitor regulatory and legislative activity with regard to LIBOR-based products to identify all necessary actions and facilitate the transition to alternative reference rates. The Company has adopted Accounting Standards Update (“ASU”) 2020-04, Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform on Financial Reporting, and the subsequent amendment, which provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform (e.g., discontinuation of LIBOR) if certain criteria are met. The Company will apply the accounting relief as relevant contract and hedge accounting relationship modifications are made during the reference rate reform transition period, and does not expect the standard to have a material impact on the consolidated financial statements. Cash and Cash Equivalents, Liquidity Risk Management and Contractual Commitments Liquidity risk involves the risk of being unable to fund assets with the appropriate duration and rate-based liability, as well as the risk of not being able to meet unexpected cash needs. Liquidity planning and management are necessary to ensure the ability to fund operations cost effectively and to meet current and future potential obligations such as loan commitments and unexpected deposit outflows. Funding sources include primarily customer-based deposits, collateral-backed borrowings, brokered deposits, cash flows from operations, cash flows from our loan and investment portfolios and asset sales, primarily secondary marketing for residential real estate mortgages and marine loans. Cash flows from operations are a significant component of liquidity risk management and the Company considers both deposit maturities and the scheduled cash flows from loan and investment maturities and payments when managing risk. The Company does not rely on and is not dependent on off-balance sheet financing or significant amounts of wholesale funding. Brokered certificates of deposit (“CDs”) at December 31, 2020 totaled $233.8 million, compared to $472.9 million at December 31, 2019. All of the brokered CDs outstanding at December 31, 2020 have maturities of 12 months or less. Deposits are a primary source of liquidity. The stability of this funding source is affected by numerous factors, including returns available to customers on alternative investments, the quality of customer service levels, perception of safety and competitive forces. The Company routinely uses debt securities and loans as collateral for secured borrowings. In the event of severe market disruptions, the Company has access to secured borrowings through the FHLB and the Federal Reserve Bank of Atlanta under its borrower-in-custody program. Cash and cash equivalents, including interest bearing deposits, totaled $404.1 million on a consolidated basis at December 31, 2020, compared to $124.5 million at December 31, 2019. Higher cash and cash equivalent balances at December 31, 2020 52 reflect the Company's decision to maintain prudent higher levels of liquidity in the current economic environment, as well as higher customer deposit balances. Contractual maturities for assets and liabilities are reviewed to meet current and expected future liquidity requirements. Sources of liquidity, both anticipated and unanticipated, are maintained through a portfolio of high-quality marketable assets, such as residential mortgage loans, available-for-sale debt securities and interest-bearing deposits. The Company is also able to provide short-term financing of its activities by selling, under an agreement to repurchase, United States Treasury and government agency debt securities not pledged to secure public deposits or trust funds. At December 31, 2020, the Company had available unsecured lines of $135.0 million and lines of credit under current lendable collateral value, which are subject to change, of $1.8 billion. In addition, the Company had $1.2 billion of debt securities and $733.3 million in residential and commercial real estate loans available as collateral. In comparison, at December 31, 2019, the Company had available unsecured lines of $130.0 million and lines of credit of $1.1 billion, and $924.2 million of debt securities and $830.0 million in residential and commercial real estate loans available as collateral. The Company has traditionally relied upon dividends from Seacoast Bank and securities offerings to provide funds to pay the Company’s expenses and to service the Company’s debt. During 2020, Seacoast Bank distributed $20.2 million to the Company and, at December 31, 2020, is eligible to distribute dividends to the Company of approximately $213.4 million without prior approval. Seacoast Bank distributed $18.1 million to the Company during 2019. At December 31, 2020, the Company had cash and cash equivalents at the parent of approximately $70.1 million compared to $53.0 million at December 31, 2019. The following table presents contractual obligations. All deposits presented in the table with indeterminate maturities such as interest bearing and noninterest bearing demand deposits, savings accounts and money market accounts are presented as having a maturity of one year or less. The Company considers these low cost deposits to be its largest, most stable funding source, despite no contracted maturity.

Total deposits increased $1.3 billion, or 24%, to $6.9 billion at December 31, 2020 compared to December 31, 2019. The FBPB and Freedom Bank acquisitions added deposits of $173.7 million and $329.7 million, respectively, in 2020. Since December 31, 2019, interest bearing deposits, which includes interest bearing demand, savings and money markets deposits, increased $1.0 billion, or 36%, to $3.8 billion at December 31, 2020, noninterest bearing demand deposits increased $699.3 million, or 44%, to $2.3 billion, and CDs decreased $353.9 million, or 30%, to $831.2 million. Noninterest demand deposits represented 33% of deposits at December 31, 2020 and 28% at December 31, 2019. Overall, customer balances increased on a year-over-year basis Customer repurchase agreements totaled $119.6 million at December 31, 2020, increasing $33.5 million, or 39%, from December 31, 2019. Repurchase agreements are offered by Seacoast to select customers who wish to sweep excess balances on a daily basis for investment purposes. The increase reflects a shift in customer balances from interest bearing deposits in 2020 as rates declined in 2020. Public funds comprise a significant amount of the outstanding balance. The Company participates in programs with third party deposit networks as part of its cash management strategy. Through these programs, the Company can offer its customers access to FDIC insurance on large balances, and the Company can retain or sell, on an overnight basis, the underlying deposits. At December 31, 2020, the Company had sold, on an overnight basis, $112.7 million in deposits. These deposits are not included in the Consolidated Balance Sheet. 53 No unsecured federal funds purchased were outstanding at December 31, 2020 or December 31, 2019. Borrowings were comprised of subordinated debt related to trust preferred securities issued by trusts organized or acquired by the Company of $71.4 million and $71.1 million at December 31, 2020 and December 31, 2019, respectively, and borrowings from the FHLB of zero and $315.0 million, respectively. Secured FHLB borrowings are an integral tool in liquidity management for the Company. The Company issued subordinated debt in conjunction with its wholly owned trust subsidiaries in connection with bank acquisitions in previous years. The acquired junior subordinated debentures (in accordance with ASC Topic 805 Business Combinations) were recorded at fair value, which collectively is $3.9 million lower than face value at December 31, 2020. This amount is being amortized into interest expense over the acquired subordinated debts’ remaining term to maturity. All trust preferred securities are guaranteed by the Company on a junior subordinated basis. Under Basel III and Federal Reserve rules, qualified trust preferred securities and other restricted capital elements can be included as Tier 1 capital, within limitations. The Company believes that its trust preferred securities qualify under these capital rules. The weighted average interest rate of our outstanding subordinated debt related to trust preferred securities was 3.07% for the year ended December 31, 2020, compared to 4.75% in 2019. Go to “Note J - Borrowings” to the Company's consolidated financial statements for more detailed information pertaining to borrowings. Off-Balance Sheet Transactions In the normal course of business, the Company may engage in a variety of financial transactions that, under generally accepted accounting principles, either are not recorded on the balance sheet or are recorded on the balance sheet in amounts that differ from the full contract or notional amounts. These transactions involve varying elements of market, credit and liquidity risk. Lending commitments include unfunded loan commitments and standby and commercial letters of credit. For loan commitments, the contractual amount of a commitment represents the maximum potential credit risk that could result if the entire commitment had been funded, the borrower had not performed according to the terms of the contract, and no collateral had been provided. A large majority of loan commitments and standby letters of credit expire without being funded, and accordingly, total contractual amounts are not representative of our actual future credit exposure or liquidity requirements. Loan commitments and letters of credit expose the Company to credit risk in the event that the customer draws on the commitment and subsequently fails to perform under the terms of the lending agreement. For commercial customers, loan commitments generally take the form of revolving credit arrangements. For retail customers, loan commitments are generally lines of credit secured by residential property. These instruments are not recorded on the balance sheet until funds are advanced under the commitment. Loan commitments were $1.5 billion at December 31, 2020, and $1.0 billion at December 31, 2019 (see “Note Q - Contingent Liabilities and Commitments with Off-Balance Sheet Risk” to the Company’s consolidated financial statements). Capital Resources and Management Table 6 summarizes the Company’s capital position and selected ratios. The Company's equity capital at December 31, 2020 increased $144.8 million, or 15%, from December 31, 2019, to $1.1 billion. The ratio of shareholders’ equity to period end total assets was 13.55% and 13.87% at December 31, 2020 and December 31, 2019, respectively. The ratio of tangible shareholders’ equity to tangible assets was 11.01% and 11.05% at December 31, 2020 and December 31, 2019, respectively. Equity has increased as a result of earnings retained by the Company, the issuance of common stock in conjunction with bank acquisitions, and as a result of increases in accumulated other comprehensive income (“AOCI”) during the year ended December 31, 2020, primarily reflecting the impact of lower interest rates on available-for-sale securities. Activity in shareholders’ equity for the year ended December 31, 2020 and December 31, 2019 follows: 54 (In thousands) Beginning balance at January 1, 2020 and 2019 Net income Cumulative change in accounting principle upon adoption of new accounting pronouncement Issuance of stock, pursuant to acquisitions Stock compensation (net of Treasury shares acquired) Change in other comprehensive income Other Ending balance at December 31, 2020 and 2019 For the Year Ended December 31, $ 2020 985,639 $ 77,764 (16,876) 62,152 5,818 15,905 — $ 1,130,402 $ 2019 864,267 98,739 — — 5,004 17,525 104 985,639 Capital ratios are well above regulatory requirements for well-capitalized institutions. Management’s use of risk-based capital ratios in its analysis of the Company’s capital adequacy are not GAAP financial measures. Seacoast’s management uses these measures to assess the quality of capital and believes that investors may find it useful in their analysis of the Company. The capital measures are not necessarily comparable to similar capital measures that may be presented by other companies and Seacoast does not nor should investors consider such non-GAAP financial measures in isolation from, or as a substitute for GAAP financial information (see “Table 6 - Capital Resources” and “Note O - Shareholders’ Equity”).

Higher earnings have been a primary contributor to this increase. As of December 31, 2020, the Bank’s leverage ratio (Tier 1 capital to adjusted total assets) was 11.03%, compared to 11.38% at December 31, 2019. The Company and Seacoast Bank are subject to various general regulatory policies and requirements relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. The appropriate federal bank regulatory authority may prohibit the payment of dividends where it has determined that the payment of dividends would be an unsafe or unsound practice. The Company is a legal entity separate and distinct from Seacoast Bank and its other subsidiaries, and the Company’s primary source of cash and liquidity, other than securities offerings and borrowings, is dividends from its bank subsidiary. Without Office of the Comptroller of the Currency (“OCC”) approval, Seacoast Bank can pay up to $213.4 million of dividends to the Company (see “Part I. Item 1. Business”). The OCC and the Federal Reserve have policies that encourage banks and bank holding companies to pay dividends from current earnings, and have the general authority to limit the dividends paid by national banks and bank holding companies, respectively, if such payment may be deemed to constitute an unsafe or unsound practice. If, in the particular circumstances, either of these federal regulators determined that the payment of dividends would constitute an unsafe or unsound banking practice, either the OCC or the Federal Reserve may, among other things, issue a cease and desist order prohibiting the payment of dividends by Seacoast Bank or the Company, respectively. Under a recently adopted Federal Reserve policy, the board of directors of a bank holding company must consider different factors to ensure that its dividend level is prudent relative to the organization’s financial position and is not based on overly optimistic earnings scenarios such as any potential events that may occur before the payment date that could affect its ability to pay, while still maintaining a strong financial position. As a general matter, the Federal Reserve has indicated that the board of directors of a bank holding company, such as Seacoast, should consult with the Federal Reserve and eliminate, defer, or significantly reduce the bank holding company’s dividends if: (i) its net income available to shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends; (ii) its prospective rate of earnings retention is not consistent with its capital needs and overall current and prospective financial condition; or (iii) it will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios. The Company has seven wholly owned trust subsidiaries that issued trust preferred securities, all of which are guaranteed by the Company on a junior subordinated basis. The Federal Reserve’s rules permit qualified trust preferred securities and other 55 restricted capital elements to be included under Basel III capital guidelines, with limitations, and net of goodwill and intangibles. The Company believes that its trust preferred securities qualify under these revised regulatory capital rules and believes that it will be able to treat all $71.4 million of trust preferred securities as Tier 1 capital. For regulatory purposes, the trust preferred securities are added to the Company’s tangible common shareholders’ equity to calculate Tier 1 capital. Critical Accounting Policies and Estimates The Company’s consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles, (“GAAP”), including prevailing practices within the financial services industry. The preparation of consolidated financial statements requires management to make judgments in the application of certain of its 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. Management, after consultation with the Company’s Audit Committee, believes the most critical accounting estimates and assumptions that involve the most difficult, subjective and complex assessments are: • the allowance and the provision for credit losses; • acquisition accounting and purchased loans; • intangible assets and impairment testing; • other fair value measurements; • impairment of debt securities, and; • contingent liabilities. The following is a discussion of the critical accounting policies intended to facilitate a reader’s understanding of the judgments, estimates and assumptions underlying these accounting policies and the possible or likely events or uncertainties known to the Company that could have a material effect on reported financial information. For more information regarding management’s judgments relating to significant accounting policies and recent accounting pronouncements, see “Note A-Significant Accounting Policies” to the Company’s consolidated financial statements. Allowance for Credit Losses – Critical Accounting Policies and Estimates On January 1, 2020, the Company adopted ASC Topic 326 - Financial Instruments - Credit Losses, which replaced the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. For loans, management estimates the allowance for credit losses using relevant available information, from both internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit losses provide the basis for 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 environmental conditions, such as changes in unemployment rates, property values, occupancy rates, and other macroeconomic metrics. The allowance for credit losses is measured on a collective basis when similar risk characteristics exist. The Company has developed an allowance model based on an analysis of probability of default (“PD”) and loss given default (“LGD”) to determine an expected loss by loan segment. PDs and LGDs are developed by analyzing the average historical loss migration of loans to default. The allowance estimation process also applies an economic forecast scenario over a three year forecast period. The forecast may utilize one scenario or a composite of scenarios based on management's judgment and expectations around the current and future macroeconomic outlook. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. For portfolio segments with a weighted average life longer than three years, the Company reverts to longer-term historical loss experience, adjusted for prepayments, to estimate losses over the remaining life of the loans within each segment. 56 Adjustments may be made to baseline reserves for some of the loan pools based on an assessment of internal and external influences on credit quality not fully reflected in the quantitative components of the allowance model. These influences may include elements such as changes in concentration, macroeconomic conditions, recent observable asset quality trends, staff turnover, regional market conditions, employment levels and loan growth. Based upon management's assessments of these factors, the Company may apply qualitative adjustments to the allowance. Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. When management determines that foreclosure is probable, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. The contractual term of a loan excludes expected extensions, renewals, and modification unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and not unconditionally cancellable by the Company. The allowance for credit losses on troubled debt restructurings (“TDRs”) is measured using the same method as all other loans held for investment, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the allowance for credit losses is determining by discounting the expected future cash flows at the original interest rate of the loan. It is the Company's practice to ensure that the charge-off policy meets or exceeds regulatory requirements. Losses on unsecured consumer loans are recognized at 90 days past due, compared to the regulatory loss criteria of 120 days. In compliance with Federal Financial Institution Examination Council guidelines, secured consumer loans, including residential real estate, are typically charged off or charged down between 120 and 180 days past due, depending on the collateral type. Commercial loans and real estate loans are typically placed on nonaccrual status when principal or interest is past due for 90 days or more, unless the loan is both secured by collateral having realizable value sufficient to discharge the debt in-full and the loan is in process of collection. Loans provided with short-term payment deferrals under the CARES Act or interagency guidance are not considered past due if in compliance with the terms of their deferral. Secured loans may be charged down to the estimated value of the collateral with previously accrued unpaid interest reversed against interest income. Subsequent charge-offs may be required as a result of changes in the market value of collateral or other repayment prospects. Initial charge-off amounts are based on valuation estimates derived from appraisals, broker price opinions, or other market information. Generally, new appraisals are not received until the foreclosure process is completed; however, collateral values are evaluated periodically based on market information and incremental charge-offs are recorded if it is determined that collateral values have declined from their initial estimates. Note F to the financial statements (titled “Allowance for Credit Losses”) summarizes the Company’s allocation of the allowance for credit losses on loans by loan segment and provides detail regarding charge-offs and recoveries for each loan segment and the composition of the loan portfolio at December 31, 2020 and 2019. Acquisition Accounting and Purchased Loans – Critical Accounting Policies and Estimates The Company accounts for acquisitions under ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. All identifiable assets acquired, including loans, are recorded at fair value. All loans acquired are recorded at fair value in accordance with the fair value methodology prescribed in ASC Topic 820, Fair Value Measurement. The fair value estimates associated with the loans include estimates related to expected prepayments and the amount and timing of expected principal, interest and other cash flows. Loans are identified as purchased credit deteriorated (“PCD”) when they have experienced more-than-insignificant deterioration in credit quality since origination. An allowance for expected credit losses on PCD loans is recorded at the date of acquisition through an adjustment to the loans’ amortized cost basis. In contrast, expected credit losses on loans not considered PCD are recognized in net income at the date of acquisition. Fair value estimates for acquired assets and assumed liabilities are based on the information available, and are subject to change for up to one year after the closing date of the acquisition as additional information relative to closing date fair values becomes available. Intangible Assets and Impairment Testing – Critical Accounting Policies and Estimates Intangible assets consist of goodwill, core deposit intangibles and loan servicing rights. Goodwill represents the excess purchase price over the fair value of net assets acquired in business acquisitions. The core deposit intangible represents the excess intangible value of acquired deposit customer relationships as determined by valuation specialists. Core deposit intangibles are amortized on a straight-line basis, and are evaluated for indications of potential impairment at least annually. 57 Goodwill is not amortized but rather is evaluated for impairment on at least an annual basis. We performed an annual impairment test of goodwill as required by ASC Topic 350, Intangibles—Goodwill and Other, in the fourth quarter of 2020 with the assistance of third-party valuation specialists, and concluded that no impairment existed. Fair value estimates for acquired assets and assumed liabilities are based on the information available, and are subject to change for up to one year after the closing date of the acquisition as additional information relative to closing date fair values becomes available. Other Fair Value Measurements – Critical Accounting Policies and Estimates The fair value of collateral-dependent loans, OREO and repossessed assets is typically based on current appraisals, which are reviewed quarterly to determine if fair value adjustments are necessary based on known changes in the market and/or the project assumptions. When necessary, the appraised value may be adjusted based on more recent appraisal assumptions received by the Company on other similar properties, the tax assessed market value, comparative sales and/or an internal valuation. Collateral-dependent loans are loans where repayment is solely dependent on the liquidation of the collateral or operation of the collateral for repayment. The Company also holds 11,330 shares of Visa Class B stock which, following resolution of Visa’s litigation, will be converted to Visa Class A shares. Under the current conversion rate that became effective September 27, 2019, the Company expects to receive 1.6228 shares of Class A stock for each share of Class B stock, for a total of 18,386 shares of Visa Class A stock. The Company's ownership is related to prior ownership in Visa’s network while Visa operated as a cooperative. This ownership is recorded on the Company's financial records at a zero basis. Impairment of Debt Securities – Critical Accounting Policies and Estimates On January 1, 2020, the Company adopted ASC Topic 326 – Financial Instruments – Credit Losses, which requires expected credit losses on both held-to-maturity (“HTM”) and available-for-sale (“AFS”) securities to be recognized through a valuation allowance instead of as a direct write-down to the amortized cost basis of the security. For HTM securities, the guidance requires management to estimate expected credit losses over the remaining expected life and recognize this estimate as an allowance for credit losses. An AFS security is considered impaired if the fair value is less than amortized cost basis. For AFS securities, if any portion of the decline in fair value is related to credit, the amount of allowance is determined as the portion related to credit, limited to the difference between the amortized cost basis and the fair value of the security. If the fair value of the security increases in subsequent periods, or changes in factors used within the credit loss assessment result in a change in the estimated credit loss, the Company would reflect the change by decreasing the allowance. If the Company has the intent to sell or believes it is more likely than not that it will be required to sell an impaired AFS security before recovery of the amortized cost basis, the credit loss is recorded as a direct write-down of the amortized cost basis. Declines in the fair value of AFS securities that are not considered credit related are recognized in Accumulated Other Comprehensive Income on the Company’s Consolidated Balance Sheet. Seacoast analyzes AFS debt securities quarterly for credit losses. The analysis is performed on an individual security basis for all securities where fair value has declined below amortized cost. Fair value is based upon pricing obtained from third party pricing services. Based on internal review procedures and the fair values provided by the pricing services, the Company believes that the fair values provided by the pricing services are consistent with the principles of ASC Topic 820, Fair Value Measurement. However, on occasion pricing provided by the pricing services may not be consistent with other observed prices in the market for similar securities. Using observable market factors, including interest rate and yield curves, volatilities, prepayment speeds, loss severities and default rates, the Company may at times validate the observed prices using a discounted cash flow model and using the observed prices for similar securities to determine the fair value of its securities. The Company utilizes both quantitative and qualitative assessments to determine if a security has a credit loss. Quantitative assessments are based on a discounted cash flow method. Qualitative assessments consider a range of factors including: percent decline in fair value, rating downgrades, subordination, duration, amortized loan-to-value, and the ability of the issuers to pay all amounts due in accordance with the contractual terms. 58 Contingent Liabilities – Critical Accounting Policies and Estimates Seacoast is subject to contingent liabilities, including judicial, regulatory and arbitration proceedings, and tax and other claims arising from the conduct of the Company's business activities. These proceedings include actions brought against the Company and/or its subsidiaries with respect to transactions in which the Company and/or its subsidiaries acted as a lender, a financial adviser, a broker or acted in a related activity. Accruals are established for legal and other claims when it becomes probable that the Company will incur an expense and the amount can be reasonably estimated. Company management, together with attorneys, consultants and other professionals, assesses the probability and estimated amounts involved in a contingency. Throughout the life of a contingency, the Company or its advisers may learn of additional information that can affect the assessments about probability or about the estimates of amounts involved. Changes in these assessments can lead to changes in recorded reserves. In addition, the actual costs of resolving these claims may be substantially higher or lower than the amounts reserved for the claims. At December 31, 2020 and 2019, the Company had no significant accruals for contingent liabilities and had no known pending matters that could potentially be significant. Item 7A. Quantitative and Qualitative Disclosures About Market Risk Interest Rate Sensitivity Fluctuations in interest rates may result in changes in the fair value of the Company’s financial instruments, cash flows and net interest income. This risk is managed using simulation modeling to calculate the most likely interest rate risk utilizing estimated loan and deposit growth. The objective is to optimize the Company’s financial position, liquidity, and net interest income while limiting volatility. Senior management regularly reviews the overall interest rate risk position and evaluates strategies to manage the risk. The Company's Asset and Liability Management Committee (“ALCO”) uses simulation analysis to monitor changes in net interest income due to changes in market interest rates. The simulation of rising, declining and flat interest rate scenarios allows management to monitor and adjust interest rate sensitivity to minimize the impact of market interest rate swings. The analysis of the impact on net interest income over a twelve month period is subjected to instantaneous changes in market rates of 100 basis point and 200 basis point increases and a 100 basis point decrease on net interest income and is monitored on a quarterly basis. The following table presents the ALCO simulation model's projected impact of a change in interest rates on the projected baseline net interest income for the 12 and 24 month periods beginning on January 1, 2021, holding all other changes in the balance sheet static. This change in interest rates assumes parallel shifts in the yield curve and does not take into account changes in the slope of the yield curve. % Change in Projected Baseline Net Interest Income 2020 2019 Changes in Interest Rates 1-12 months 13-24 months 1-12 months 13-24 months +2.00% +1.00% Current -1.00% 7.6% 3.9 — (4.5) 14.0% 7.4 — (10.1) 3.6% 1.6 — (1.5) 6.7% 2.8 — (5.4) The Company had a positive gap position based on contractual and prepayment assumptions for the next 12 months, with a positive cumulative interest rate sensitivity gap as a percentage of total earning assets of 26.3% as of December 31, 2020. This result includes assumptions for core deposit re-pricing validated for the Company by an independent third party consulting group. The computations of interest rate risk do not necessarily include certain actions management may undertake to manage this risk in response to changes in interest rates. Derivative financial instruments, such as interest rate swaps, options, caps, floors, futures and forward contracts may be utilized as components of the Company’s risk management profile. 59 Market Risk Market risk refers to potential losses arising from changes in interest rates, and other relevant market rates or prices. Interest rate risk, defined as the exposure of net interest income and Economic Value of Equity (“EVE”) to adverse movements in interest rates, is the Company’s primary market risk, and mainly arises from the structure of the balance sheet (non-trading activities). The Company is also exposed to market risk in its investing activities. The ALCO meets regularly and is responsible for reviewing the interest rate sensitivity position of the Company and establishing policies to monitor and limit exposure to interest rate risk. The policies established by the ALCO are reviewed and approved by the Company’s board of directors. The primary goal of interest rate risk management is to control exposure to interest rate risk, within policy limits approved by the board of directors. These limits reflect the Company’s tolerance for interest rate risk over short-term and long-term horizons. The Company also performs valuation analyses, which are used for evaluating levels of risk present in the balance sheet that might not be taken into account in the net interest income simulation analyses. Whereas net interest income simulation highlights exposures over a relatively short time horizon, valuation analysis incorporates all cash flows over the estimated remaining life of all balance sheet positions. The valuation of the balance sheet, at a point in time, is defined as the discounted present value of asset cash flows minus the discounted value of liability cash flows, the net result of which is the EVE. The sensitivity of EVE to changes in the level of interest rates is a measure of the longer-term re-pricing risks and options risks embedded in the balance sheet. In contrast to the net interest income simulation, which assumes interest rates will change over a period of time, EVE uses instantaneous changes in rates. EVE values only the current balance sheet, and does not incorporate the growth assumptions that are used in the net interest income simulation model. As with the net interest income simulation model, assumptions about the timing and variability of balance sheet cash flows are critical in the EVE analysis. Particularly important are the assumptions driving prepayments and the expected changes in balances and pricing of the indeterminate life deposit portfolios. Core deposits are a more significant funding source for the Company, making the lives attached to core deposits more important to the accuracy of our modeling of EVE. The Company periodically reassesses its assumptions regarding the indeterminate lives of core deposits utilizing an independent third party resource to assist. With lower interest rates over a prolonged period, the average lives of core deposits have trended higher and favorably impacted our model estimates of EVE for higher rates. The following table presents the projected impact of a change in interest rates on the balance sheet. This change in interest rates assumes parallel shifts in the yield curve and does not take into account changes in the slope of the yield curve. Changes in Interest Rates +2.00% +1.00% Current -1.00% % Change in Economic Value of Equity 2020 23.7% 13.3 — (19.2) 2019 13.2% 7.1 — (16.4) While an instantaneous and severe shift in interest rates is used in this analysis to provide an estimate of exposure under an extremely adverse scenario, a gradual shift in interest rates would have a much more modest impact. Since EVE measures the discounted present value of cash flows over the estimated lives of instruments, the change in EVE does not directly correlate to the degree that earnings would be impacted over a shorter time horizon, i.e., the next fiscal year. Further, EVE does not take into account factors such as future balance sheet growth, changes in product mix, change in yield curve relationships, and changing product spreads that could mitigate the adverse impact of changes in interest rates. Effects of Inflation and Changing Prices The condensed consolidated financial statements and related financial data presented herein have been prepared in accordance with U.S. GAAP, which require the measurement of financial position and operating results in terms of historical dollars, without considering changes in the relative purchasing power of money, over time, due to inflation. Unlike most industrial companies, virtually all of the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates have a more significant impact on a financial institution’s performance than the general level of inflation. However, inflation affects financial institutions by increasing their cost of goods and services purchased, as well as the cost of salaries and benefits, occupancy expense, and similar items. Inflation and related increases in interest rates generally decrease the market value of investments and loans held and may adversely affect liquidity, earnings, and shareholders’ equity.

Financial Statements and Supplementary Data REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM Shareholders and the Board of Directors of Seacoast Banking Corporation of Florida Stuart, Florida Opinions on the Financial Statements and Internal Control over Financial Reporting We have audited the accompanying consolidated balance sheets of Seacoast Banking Corporation of Florida (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of income, comprehensive income, shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2020, and the related notes (collectively referred to as the “financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control – Integrated Framework: (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2020 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control – Integrated Framework: (2013) issued by COSO. Change in Accounting Principle As discussed in Note A to the financial statements, the Company has changed its method of accounting for credit losses effective January 1, 2020 due to the adoption of Financial Accounting Standards Board Accounting Standards Codification No. 326, Financial Instruments – Credit Losses (ASC 326). The Company adopted the new credit loss standard using the modified retrospective method such that prior period amounts are not adjusted and continue to be reported in accordance with previously applicable generally accepted accounting principles. The adoption of the new credit loss standard and its subsequent application is also communicated as a critical audit matter below. Basis for Opinions The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. 81 Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Allowance for Credit Losses on Loans and Provision Expense In accordance with Accounting Standards Update (the “ASU”) 2016-13, Financial Instruments —Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, the Company adopted Accounting Standards Codification (“ASC”) 326 as of January 1, 2020 as described in Notes A and F of the consolidated financial statements using the modified retrospective method. See also the explanatory paragraph above for the change in accounting principle. The allowance for credit losses (the “ACL”) is an accounting estimate of expected credit losses over the contractual life of financial assets carried at amortized cost and off-balance-sheet credit exposures. The ASU requires a financial asset (or a group of financial assets), including the Company's loan portfolio, measured at amortized cost to be presented at the net amount expected to be collected. Estimates of expected credit losses for loans are based on historical experience, current conditions and reasonable and supportable forecasts over the expected life of the loans. In order to estimate the expected credit losses, the Company implemented a new loss estimation model. The Company disclosed the impact of adoption of this standard on January 1, 2020 with a $21.2 million increase to the allowance for credit losses, a $1.8 million increase for unfunded loan commitments and a $16.9 million decrease to retained earnings for the cumulative effect adjustment recorded upon adoption. Provision expense for loans for the year ending December 31, 2020 was $37.8 million and the allowance for credit losses on loans at December 31, 2020 was $92.7 million. The Company estimates expected credit losses for loans using a methodology based on the probability of default (“PD”) and loss given default (“LGD”), which is defined as credit loss incurred when an obligor of the bank defaults. PDs and LGDs are developed by analyzing the average historical loss migration of loans to default. The ACL estimation process for loans also applies an economic forecast scenario over a three-year forecast period. The forecast may use a single scenario or a composite of scenarios. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments. For portfolio segments with a weighted average life longer than three years, the Company reverts to longer-term historical loss experience, adjusted for prepayments, to estimate losses over the remaining life of the loans within each segment. Qualitative adjustments are applied to the quantitative component to adjust for factors such as current conditions and the possibility that the characteristics of the economic downturn could be sustained over a more extended period of time. Adjustments may be made to baseline reserves based on an assessment of internal and external influences on credit quality not fully reflected in the quantitative components of the allowance model. These influences may include elements such as changes in concentration, macroeconomic conditions, recent observable asset quality trends, staff turnover, regional market conditions, employment levels and loan growth. These qualitative adjustments are based upon management's assessments of the factors. We determined that auditing the allowance for credit losses on loans was a critical audit matter because of the extent of auditor judgment applied and significant audit effort to evaluate the significant subjective and complex judgments made by 82 management throughout the initial adoption and subsequent application processes, including the need to involve our valuation services specialists. The principal considerations resulting in our determination included the following: • • • • Significant auditor judgment and audit effort to evaluate the appropriateness of selection of the loss estimation models, appropriateness of loan segmentation, and the reasonableness of PD and LGD assumptions Significant auditor judgment in evaluating the selection and application of the reasonable and supportable forecast of economic variables Significant auditor judgment and effort were used in evaluating the qualitative adjustments used in the calculation Significant audit effort related to the completeness and accuracy of the high volume of data used to develop assumptions and in the model computation The primary procedures performed to address the critical audit matter included: • • • Testing the effectiveness of management’s internal controls over the Company’s significant model assumptions and judgments, loan segmentation, reasonable and supportable forecasts, qualitative adjustments, information systems and model validation Testing the effectiveness of controls over the completeness and accuracy of historical inputs used in the development of the PD models and LGD assumptions, data imputation, use of third-party data, and loan data used in the computation Testing the effectiveness of controls over the Company’s preparation and review of the allowance for credit loss calculation, including data used as the basis for adjustments related to the qualitative adjustments and the development and reasonableness of qualitative adjustments and mathematical accuracy and appropriateness of the overall calculation • With the assistance of our valuation specialists, evaluating the reasonableness of assumptions and judgments related to the PD, LGD and loan segmentation, the conceptual design of the credit loss estimation models, model assumption sensitivity analysis and the adequacy of the independent model validation • • • Evaluating management’s judgments in the selection and application of reasonable and supportable forecast of economic variables Substantively testing management’s process for developing the qualitative factors and assessing reasonableness, relevance and reliability of data used to develop factors, including evaluating management’s judgments and assumptions for reasonableness Substantively testing the mathematical accuracy of the PD and LGD model on a pooled loan level with the assistance of valuation specialists, including the completeness and accuracy of loan data used in the model /s/ Crowe LLP Crowe LLP We have served as the Company's auditor since 2014.

Banking Corporation of Florida and Subsidiaries Note A - Significant Accounting Policies General: Seacoast Banking Corporation of Florida (“Seacoast” or the “Company”) is a single segment financial holding company with one operating subsidiary bank, Seacoast National Bank (“Seacoast Bank”). The Company provides integrated financial services including commercial and retail banking, wealth management, and mortgage services to customers through advanced banking solutions and a network of traditional branch offices and commercial banking centers operated by Seacoast Bank. Seacoast operates primarily in Florida, with concentrations in the state's fastest growing markets, each with unique characteristics and opportunities. Offices stretch from the southeast, including Fort Lauderdale, Boca Raton and Palm Beach, north along the east coast to the Daytona area, into Orlando and Central Florida and the adjacent Tampa market, and west to Okeechobee and surrounding counties. The consolidated financial statements include the accounts of Seacoast and all its majority-owned subsidiaries but exclude trusts created for the issuance of trust preferred securities. In consolidation, all significant intercompany accounts and transactions are eliminated. The accounting and reporting policies of the Company are in accordance with accounting principles generally accepted in the United States of America, and they conform to general practices within the applicable industries. Certain prior period amounts have been reclassified to conform to the current period presentation. Use of Estimates: The preparation of 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 Adopted Accounting Pronouncements: On January 1, 2020, the Company adopted ASC Topic 326 - Financial Instruments - Credit Losses, which replaced the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity (“HTM”) debt securities. It also applies to off-balance sheet credit exposure such as loan commitments, standby letters of credit, financial guarantees and other similar instruments. In addition, ASC Topic 326 changed the accounting for impairment of available-for-sale (“AFS”) debt securities. The Company adopted ASC Topic 326 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. Results for the reporting period beginning after January 1, 2020 are presented under ASC Topic 326, while prior amounts continue to be reported in accordance with previously applicable GAAP. The following table reflects the cumulative effect of adoption: (in thousands) Loans Allowance for credit losses Reserve for unfunded commitments Deferred tax assets Retained earnings December 31, 2019 CECL adoption impact January 1, 2020 $ 5,198,404 $ (706) $ 5,197,698 35,154 140 16,457 195,813 21,226 1,837 (5,481) (16,876) 56,380 1,977 10,976 178,937 ASC Topic 326 introduced new definitions and criteria for categorizing purchased loans. Loans that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination are classified as purchased credit deteriorated (“PCD”). Acquired loans which do not meet the definition of PCD are classified by the Company as acquired Non-PCD. At the date of adoption, the Company reclassified all loans previously classified as purchased credit 91 impaired (“PCI”) to PCD, and increased the allowance $0.7 million with a corresponding adjustment to these loans' amortized cost basis. The remaining noncredit discount on loans previously classified as PCI was $0.9 million, which will be accreted into interest income over the remaining life of the loans. Under CECL, the Company estimates the allowance using relevant available information, from both internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. 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 environmental conditions, such as changes in unemployment rates, property values, occupancy rates, and other macroeconomic metrics. For loans analyzed on a collective basis, the Company has developed an allowance model based on an analysis of the probability of default (“PD”) and loss given default (“LGD”) to determine an expected loss by loan segment. PDs and LGDs are developed by analyzing the average historical loss migration of loans to default. The Company excludes accrued interest on loans from its determination of allowance. The allowance estimation process also applies an economic forecast scenario over a three year forecast period. The forecast may utilize one scenario or a composite of scenarios based on management's judgment and expectations around the current and future macroeconomic outlook. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term of a loan excludes expected extensions, renewals, and modification unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and not unconditionally cancellable by the Company. For portfolio segments with a weighted average life longer than three years, the Company reverts to longer term historical loss experience, adjusted for prepayments, to estimate losses over the remaining life of the loans within each segment. Adjustments may be made to baseline reserves for some of the loan pools based on an assessment of internal and external influences on credit quality not fully reflected in the quantitative components of the allowance model. These influences may include elements such as changes in concentration, macroeconomic conditions, recent observable asset quality trends, staff turnover, regional market conditions, employment levels and loan growth. Based upon management's assessments of these factors, the Company may apply qualitative adjustments to the allowance. Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. When management determines that foreclosure is probable, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. 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. In addition, the credit rating on all the Company's HTM debt securities as of the date of adoption is AA+. There is no history of the government withholding or limiting support to these agencies, nor is there any indication of a change to that historical support. 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 zero risk of loss if default were to occur. As a result, the Company recorded no allowance for HTM debt securities with fair value less than amortized cost basis at the date of adoption. ASC Topic 326 amended the existing other-than-temporary-impairment guidance for AFS securities, requiring credit losses to be recorded as an allowance rather than through a permanent write-down. When evaluating AFS debt securities under ASC Topic 326, the Company has evaluated whether the decline in fair value is attributed to credit losses or other factors using both quantitative and qualitative analyses, including cash flow analysis, review of credit ratings, remaining payment terms, prepayment speeds and analysis of macro-economic conditions. At the date of adoption, collateralized loan obligations had unrealized losses of $1.2 million. The collateral for these securities is first lien senior secured corporate debt, and the Company holds senior tranches rated A or higher. Based on this analysis, the Company believes that the unrealized loss position for AFS debt securities at the time of adoption was the result of both broad investment type spreads and the current rate environment. Each investment is expected to recover its price depreciation over its holding period as it moves to maturity and the Company has the intent and ability to hold these securities to maturity if necessary. As a result of this evaluation, the Company concluded that no allowance was appropriate at the date of adoption. Cash and Cash Equivalents: Cash and cash equivalents include cash and due from banks and interest-bearing bank balances. Cash equivalents have original maturities of three months or less, and accordingly, the carrying amount of these instruments is deemed to be a reasonable estimate of fair value. 92 Time Deposits with Other Banks: Time deposits with other banks consist of certificates of deposit with original maturities greater than three months and are carried at cost. Securities Purchased and Sold Agreements: Securities purchased under resale agreements and securities sold under repurchase agreements are generally accounted for as collateralized financing transactions and are recorded at the amount at which the securities were acquired or sold plus accrued interest. It is the Company’s policy to take possession of securities purchased under resale agreements, which are primarily U.S. government and government agency securities. The fair value of securities purchased and sold is monitored and collateral is obtained from or returned to the counterparty when appropriate. Securities: Debt securities are classified at date of purchase as available-for-sale or held-to-maturity. Debt securities that may be sold as part of the Company's asset/liability management or in response to, or in anticipation of, changes in interest rates and resulting prepayment risk, or for other factors are stated at fair value with unrealized gains or losses reflected as a component of shareholders' equity net of tax or included in noninterest income as appropriate. Debt securities that the Company has the ability and intent to hold to maturity are carried at amortized cost. Equity securities are stated at fair value with unrealized gains or losses included in noninterest income as securities gains or losses. 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. Realized gains and losses are included in noninterest income as investment securities gains (losses). Interest and dividends on securities, including amortization of premiums and accretion of discounts on debt securities, is recognized in interest income on an accrual basis using the interest method. The Company anticipates prepayments of principal in the calculation of the effective yield for collateralized mortgage obligations and mortgage backed securities by obtaining estimates of prepayments from independent third parties. The adjusted cost of each specific security sold is used to compute realized gains or losses on the sale of securities on a trade date basis. Seacoast Bank is a member of the Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank (“FRB”) systems. Members are required to own a certain amount of FHLB and FRB stock based on the level of borrowings and other factors, and may invest in additional amounts. Both cash and stock dividends are reported as income. Loans Held for Sale: The Company has elected to account for residential mortgage loans originated as held for sale at fair value. Changes in fair value are measured and recorded in Mortgage Banking Fees in noninterest income each period. The Company designates other loans as held for sale when it has the intent to sell them. Such loans are transferred to held for sale at the lower of cost or estimated fair value less cost to sell. At the time of transfer, write-downs on the loans are recorded as charge-offs, establishing a new cost basis upon transfer. Loans Held for Investment: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are considered held for investment. Loans originated by Seacoast and held for investment are recognized at the principal amount outstanding, net of unearned income and amounts charged off. Unearned income includes discounts, premiums and deferred loan origination fees reduced by loan origination costs. Unearned income on loans is amortized to interest income over the life of the related loan using the effective interest rate method. Interest income is recognized on an accrual basis. As a part of business acquisitions, the Company acquires loans that are recorded at fair value on the acquisition date. Accordingly, the associated allowance for credit losses related to these loans is not carried over at the acquisition date. Any losses after acquisition are recognized through the allowance for credit losses. Loans that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination are classified as purchased credit deteriorated (“PCD”). Acquired loans that do not meet the definition of PCD are classified by the Company as acquired Non- PCD. An allowance for expected credit losses on PCD loans is recorded at the date of acquisition through an adjustment to the loans' amortized cost basis. In contrast, expected credit losses on loans not considered PCD are recognized through the provision for credit losses in net income at the date of acquisition. The accrual of interest is generally discontinued on loans, except consumer loans, that become 90 days past due as to principal or interest unless collection of both principal and interest is assured by way of collateralization, guarantees or other security. When interest accruals are discontinued, unpaid interest is reversed against interest income. Consumer loans that become 120 days past due are generally charged off. When borrowers demonstrate over an extended period the ability to repay a loan in accordance with the contractual terms of a loan classified as nonaccrual, the loan is returned to accrual status. Interest income on nonaccrual loans is either recorded using the cash basis method of accounting or recognized after the principal has been reduced to zero, depending on the type of loan. 93 In response to the COVID-19 pandemic beginning in early 2020, rules defined in the Coronavirus Aid, Relief and Economic Security (“CARES”) Act and a joint statement issued by federal regulators in consultation with FASB provide financial institutions with the option not to apply troubled debt restructure (“TDR”) accounting to eligible loan modifications provided to borrowers affected by the economic impact of the COVID-19 pandemic. Outside of this guidance, a loan for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulty, is considered to be a TDR. The allowance for credit losses on a TDR is measured using the same method as all other loans held for investment, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the allowance for credit losses is determined by discounting the expected future cash flows at the original interest rate of the loan. It is the Company's practice to ensure that the charge-off policy meets or exceeds regulatory minimums. Losses on unsecured consumer loans are recognized at 90 days past due, compared to the regulatory loss criteria of 120 days. In compliance with Federal Financial Institution Examination Council guidelines, secured consumer loans, including residential real estate, are typically charged-off or charged down between 120 and 180 days past due, depending on the collateral type. Commercial loans and real estate loans are typically placed on nonaccrual status when principal or interest is past due for 90 days or more, unless the loan is both secured by collateral having realizable value sufficient to discharge the debt in-full and the loan is in process of collection. Secured loans may be charged-down to the estimated value of the collateral with previously accrued unpaid interest reversed against interest income. Subsequent charge-offs may be required as a result of changes in the market value of collateral or other repayment prospects. Initial charge-off amounts are based on valuation estimates derived from appraisals, broker price opinions, or other market information. Generally, new appraisals are not received until the foreclosure process is completed; however, collateral values are evaluated periodically based on market information and incremental charge-offs are recorded if it is determined that collateral values have declined from their initial estimates. Derivative Instruments and Hedging Activities: The Company enters into derivative contracts, including swaps and floors, to meet the needs of customers who request such services and to manage the Company's exposure to interest rate fluctuations. Derivative contracts are carried at fair value and recorded in the consolidated balance sheet within other assets or other liabilities. The gain or loss resulting from changes in the fair value of interest rate swaps designated and qualifying as cash flow hedging instruments is initially reported as a component of other comprehensive income and subsequently reclassified into earnings through interest income in the same period in which the hedged transaction affects earnings. The Company discontinues hedge accounting prospectively when it is determined that the derivative contract is no longer effective in offsetting changes in the cash flows of the hedged item, the derivative expires or is terminated, management determines that the designation of the derivative as a hedging instrument is no longer appropriate or, for a cash flow hedge, the occurrence of the forecasted transaction is no longer probable. When hedge accounting on a cash flow hedge is discontinued, any subsequent changes in fair value of the derivative are recognized in earnings. The cumulative unrealized gain or loss related to a discontinuing cash flow hedge continues to be reported in AOCI and is subsequently reclassified into earnings in the same period in which the hedged transactions affects earnings, unless it is probable that the forecasted transaction will not occur by the end of the originally specified time period, in which case the cumulative unrealized gain or loss in AOCI is reclassified into earnings immediately. Cash flows resulting from derivative financial instruments that are accounted for as hedges are classified in the cash flow statement in the same category as the cash flows from the hedged items. See additional disclosures related to derivative instruments and hedging activities in “Note G – Derivatives”. Loan Commitments and Letters of Credit: Loan commitments and letters of credit are an off-balance sheet item and represent commitments to make loans or lines of credit available to borrowers. The face amount of these commitments represents an exposure to loss, before considering customer collateral or ability to repay. Such commitments are recognized as loans when funded. The Company estimates a reserve for potential losses on unfunded commitments, which is reported separately from the allowance for credit losses within other liabilities. The reserve is based upon the same quantitative and qualitative factors applied to the collectively evaluated loan portfolio. Fees received for providing loan commitments and letters of credit that may result in loans are typically deferred and amortized to interest income over the life of the related loan, beginning with the initial borrowing. Fees on commitments and letters of credit are amortized to noninterest income as banking fees and commissions on a straight-line basis over the commitment period when funding is not expected. Fair Value Measurements: The Company measures or monitors the fair value of many of its assets and liabilities. Certain assets are measured on a recurring basis, including available-for-sale securities and loans held for sale. These assets are carried at fair value on the Company’s balance sheets. Additionally, fair value is measured on a non-recurring basis to evaluate assets or 94 liabilities for impairment or for disclosure purposes. Examples include collateral-dependent loans, OREO, loan servicing rights, goodwill, and long-lived assets. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, the Company uses various valuation techniques and assumptions when estimating fair value. The Company applies the following fair value hierarchy: Level 1 – Assets or liabilities for which the identical item is traded on an active exchange, such as publicly-traded instruments or futures contracts. Level 2 – Assets and liabilities valued based on observable market data for similar instruments. Level 3 – Assets and liabilities for which significant valuation assumptions are not readily observable in the market; instruments valued based on the best available data, some of which is internally-developed, and considers risk premiums that a market participant would require. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at and/or marked to fair value, the Company considers the principal market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability. When possible, the Company looks to active and observable markets to price identical assets or liabilities. When identical assets and liabilities are not traded in active markets, the Company looks to market observable data for similar assets and liabilities. Nevertheless, certain assets and liabilities are not actively traded in observable markets and the Company must use alternative valuation techniques to derive a fair value measurement. Bank Premises and Equipment: Bank premises and equipment are stated at cost, less accumulated depreciation and amortization. Premises and equipment include certain costs associated with the acquisition of leasehold improvements. Depreciation and amortization are recognized principally by the straight-line method, over the estimated useful lives as follows: buildings - 25-40 years, leasehold improvements 5-25 years, furniture and equipment - 3-12 years. Leasehold improvements typically amortize over the shorter of lease terms or estimated useful life. Premises and equipment and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are written down to fair value with a corresponding impact to noninterest expense Other Real Estate Owned: Other real estate owned (“OREO”) consists primarily of real estate acquired in lieu of unpaid loan balances. These assets are carried at an amount equal to the loan balance prior to foreclosure plus costs incurred for improvements to the property, but no more than the estimated fair value of the property less estimated selling costs. Any valuation adjustments required at the date of transfer are charged to the allowance for credit losses. Subsequently, unrealized losses and realized gains and losses are included in other noninterest expense. Operating results from OREO are recorded in other noninterest expense. OREO may also include bank premises no longer utilized in the course of the Company's business (closed branches) that are initially recorded at the lower of carrying value or fair value, less costs to sell. If fair value of the premises is less than amortized book value, a write down is recorded through noninterest expense. Costs to maintain the facility are expensed. Intangible assets. The Company’s intangible assets consist of goodwill, core deposit intangibles (CDIs) and mortgage servicing rights. Goodwill results from business combinations and represents the difference between the purchase price and the fair value of net assets acquired. Goodwill may be adjusted for up to one year from the acquisition date in the event new information is obtained which, if known at the date of acquisitions would have impacted the fair value of the acquired assets and liabilities. Goodwill is considered to have an indefinite useful life and is not amortized, but rather tested for impairment annually in the fourth quarter, or more often if circumstances arise that may indicate risk of impairment. If impaired, goodwill is written down with a corresponding impact to noninterest expense. The Company recognizes CDIs that result from either whole bank acquisitions or branch acquisitions. They are initially measured at fair value and then amortized over periods ranging from six to eight years on a straight line basis. The Company evaluates CDIs for impairment annually, or more often if circumstances arise that may indicate risk of impairment. If impaired, the CDI is written down with a corresponding impact to noninterest expense. Bank owned life insurance (BOLI): The Company, through its subsidiary bank, has purchased or acquired through bank acquisitions, life insurance policies on certain key executives. BOLI is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. 95 Leases: Arrangements are analyzed at inception to determine the existence of a lease. Right-of-use assets (ROUAs) represent the right to use the underlying asset and lease liabilities represent the obligation to make lease payments for the lease term. Operating lease ROUAs and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the appropriate term and information available at commencement date in determining the present value of lease payments. The lease term may include options to extend the lease when it is reasonably certain that the option will be exercised. ROUAs and operating lease liabilities are reported in Other Assets and Other Liabilities, respectively, in the Consolidated Balance Sheet. Lease expense for lease payments is recognized on a straight-line basis over the lease term and is classified as Occupancy or Furniture and Equipment expense based on the subject asset. Revenue Recognition: Revenue recognized reflects the consideration to which the Company expects to be entitled in exchange for the services provided and is recognized when the promised services (performance obligations) are transferred to a customer, requiring the application of the following five-steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. Relevant activity includes: • Service Charges on Deposits: Seacoast Bank offers a variety of deposit-related services to its customers through several delivery channels including branch offices, ATMs, telephone, mobile, and internet banking. Transaction-based fees are recognized when services, each of which represents a performance obligation, are satisfied. Service fees may be assessed monthly, quarterly, or annually; however, the account agreements to which these fees relate can be canceled at any time by Seacoast and/or the customer. Therefore, the contract term is considered a single day (a day- to-day contract). • Wealth Management Income: The Company earns trust fees from fiduciary services provided to trust customers, which include custody of assets, recordkeeping, collection and distribution of funds. Fees are earned over time and accrued monthly as the Company provides services, and are generally assessed based on the market value of the trust assets under management at a particular date or over a particular period. The Company also earns commissions and fees from investment brokerage services provided to its customers through an arrangement with a third-party service provider. Commissions received from the third-party service provider are recorded monthly and are based upon customer activity. Fees are earned over time and accrued monthly as services are provided. The Company acts as an agent in this arrangement and therefore presents the brokerage commissions and fees net of related costs. • Interchange Income: Fees earned on card transactions depend upon the volume of activity, as well as the fees permitted by the payment network. Such fees are recognized by the Company upon fulfilling its performance obligation to approve the card transaction. Treasury Stock: The Company's repurchase of shares of its common stock are recorded at cost as treasury stock and result in a reduction of shareholders' equity. Activity in treasury stock represents shares traded to offset employee payroll taxes on vested shares. Shares held in treasury are used for employee share purchases through the Company's stock purchase plan. Stock-Based Compensation: The stock option plans are accounted for under ASC Topic 718 - Compensation - Stock Compensation and the fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with market assumptions. This amount is amortized on a straight-line basis over the vesting period, generally 5 years. For restricted stock awards, which generally vest based on continued service with the Company, the deferred compensation is measured as the fair value of the shares on the date of grant, and the deferred compensation is amortized as salaries and employee benefits in accordance with the applicable vesting schedule, generally straight-line over three years. Some shares vest based upon the Company achieving certain performance goals and salary amortization expense is based on an estimate of the most likely results on a straight line basis. The Company accounts for forfeitures as they occur. Income Taxes: The Company uses the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are determined based on temporary differences between the carrying amounts of assets and liabilities in the consolidated financial statements and their related tax bases and are measured using the enacted tax rates and laws that are in effect. A valuation allowance is recognized for a deferred tax asset if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax asset will not be realized. The effect on deferred tax assets and liabilities of a change in rates is recognized as income or expense in the period in which the change occurs. Earnings per Share: Basic earnings per share are computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during each period. Diluted earnings per share are based on the 96 weighted-average number of common shares outstanding during each period, plus common share equivalents calculated for stock options and performance restricted stock outstanding using the treasury stock method. Note B - Recently Issued Accounting Standards, Not Adopted at December 31, 2020 None this period. Note C - Cash, Dividend and Loan Restrictions In the normal course of business, the Company and Seacoast Bank enter into agreements, or are subject to regulatory agreements that result in cash, debt and dividend restrictions. A summary of the most restrictive items follows: Seacoast Bank may be required to maintain reserve balances with the Federal Reserve Bank. There was no reserve requirement at December 31, 2020. The reserve requirement at December 31, 2019 was $38.7 million. The average amount of the reserve requirement in 2020 was $4.8 million compared to $7.9 million in 2019. Under Federal Reserve regulation, Seacoast Bank is limited as to the amount it may loan to its affiliates, including the Company, unless such loans are collateralized by specified obligations. At December 31, 2020, the maximum amount available for transfer from Seacoast Bank to the Company in the form of loans approximated $90.1 million, if the Company has sufficient acceptable collateral. There were no loans made to affiliates during the periods ending December 31, 2020 and 2019. 97 Note D - Securities The amortized cost, gross unrealized gains and losses and fair value of available-for-sale and held-to-maturity securities at December 31, 2020 and December 31, 2019 are summarized as follows: (In thousands) Available-for-Sale Debt Securities Amortized Cost December 31, 2020 Gross Gross Unrealized Unrealized Losses Gains Fair Value U.S. Treasury securities and obligations of U.S. government agencies Mortgage-backed securities and collateralized mortgage obligations of U.S. government-sponsored entities Private mortgage-backed securities and collateralized mortgage obligations Collateralized loan obligations Obligations of state and political subdivisions $ 8,250 $ 528 $ (1) $ 8,777 1,038,437 23,457 (1,240) 1,060,654 89,284 202,563 33,005 2,131 279 2,321 (210) 91,205 (647) 202,195 — 35,326 Totals $ 1,371,539 $ 28,716 $ (2,098) $ 1,398,157 Held-to-Maturity Debt Securities Mortgage-backed securities of U.S. government- sponsored entities Totals $ $ 184,484 $ 7,818 $ (123) $ 192,179 184,484 $ 7,818 $ (123) $ 192,179 (In thousands) Available-for-Sale Debt Securities U.S. Treasury securities and obligations of U.S. government agencies Mortgage-backed securities and collateralized mortgage obligations of U.S. government-sponsored entities Private mortgage-backed securities and collateralized mortgage obligations Collateralized loan obligations Obligations of state and political subdivisions Totals Held-to-Maturity Debt Securities Mortgage-backed securities of U.S. government- sponsored entities Totals Amortized Cost December 31, 2019 Gross Gross Unrealized Unrealized Losses Gains Fair Value $ 9,914 $ 204 $ (4) $ 10,114 604,934 5,784 (1,511) 609,207 56,005 1,561 (5) 57,561 239,364 30,548 940,765 $ 7 1,208 8,764 $ (1,153) (1) (2,674) $ 238,218 31,755 946,855 261,369 $ 2,717 $ (1,873) $ 262,213 261,369 $ 2,717 $ (1,873) $ 262,213 $ $ $ Proceeds from sales of debt securities during 2020 were $96.7 million, with gross gains of $2.4 million and gross losses of $1.3 million.

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 December 31, 2020, no allowance for credit losses has been recorded. At December 31, 2020, the Company had $0.6 million of unrealized losses in uncapped 3-month LIBOR floating rate collateralized loan obligations (“CLOs”) having a fair value of $177.2 million. CLOs are special purpose vehicles and those in which the Company has acquired nearly all first-lien, broadly syndicated corporate loans across a diversified band of industries while providing support to senior tranche investors. As of December 31, 2020, all positions held by the Company are in AAA and AA tranches, with average credit support of 35% and 25%, 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 movement and not changes in credit quality, and expects to recover the entire amortized cost basis of these securities. Therefore, at December 31, 2020, no allowance for credit losses has been recorded. At December 31, 2020, 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 $24.0 million. The collateral underlying these mortgage investments is primarily residential real estate. The securities have average credit support of 22%. 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 December 31, 2020, 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. Despite the emergence of significant market changes and increasing degrees of uncertainty that occurred in the U.S. economy in 2020, there has to date been no specific impact on the agencies or changes in the nature or quality of the guarantee they provide. As a result, as of December 31, 2020, no allowance for credit losses has been recorded. Included in other assets at December 31, 2020 is $33.9 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 AFS and HTM debt securities of $3.2 million and $0.4 million at December 31, 2020, respectively, and $3.8 million and $0.6 million at December 31, 2019, respectively, is included in other assets. Also included in other assets is a $6.5 million investment in a mutual fund carried at fair value. 100 The Company holds 11,330 shares of Visa Class B stock which, following resolution of Visa litigation, will be converted to Visa Class A shares. Under the current conversion ratio that became effective September 27, 2019, the Company would receive 1.6228 shares of Class A stock for each share of Class B stock for a total of 18,386 shares of Visa Class A stock. The ownership of Visa stock is related to prior ownership in Visa's network, while Visa operated as a cooperative. This ownership is recorded on the Company's financial records at zero basis. Note E - 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. 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. With the adoption of ASC Topic 326 -Financial Instruments - Credit Losses on January 1, 2020, the Company re-evaluated the aggregation of loans into segments, and separated Commercial Real Estate - Owner Occupied from Commercial Real Estate - Non Owner Occupied. In prior years, all Commercial Real Estate loans were considered a single segment.

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. 105 The following tables present the risk rating of loans by year of origination as of: (In thousands) 2020 2019 2018 2017 2016 Prior Revolving Total December 31, 2020 Construction and Land Development Risk Ratings: Pass Special Mention Substandard Substandard Impaired Doubtful Total Commercial real estate - owner occupied Risk Ratings: Pass Special Mention Substandard Substandard Impaired Doubtful Total Commercial real estate - non-owner occupied Risk Ratings: Pass Special Mention Substandard Substandard Impaired Doubtful Total Residential real estate Risk Ratings: Pass Special Mention Substandard Substandard Impaired Doubtful Total Commercial and financial Risk Ratings: Pass Special Mention Substandard Substandard Impaired Doubtful1 Total $ 62,107 $ 52,384 $ 46,067 $ 15,873 $ 7,335 $ 17,873 $ 35,324 $ 236,963 206 — — — 245 5,918 — — — — — — — — 37 — — — — — 1,449 51 239 — — — — — 7,818 51 276 — 62,313 52,629 51,985 15,910 7,335 19,612 35,324 245,108 155,953 198,559 156,276 138,341 148,389 287,772 14,255 1,099,545 5,773 1,858 3,305 — — — 3,151 — — 747 — — 4,709 1,362 — 4,471 1,955 — — 4,050 5,508 4,874 — 2 — — — 19,459 12,172 10,134 — 161,726 203,568 160,328 144,412 154,815 302,204 14,257 1,141,310 159,299 313,287 201,112 123,357 175,623 356,943 8,596 1,338,217 — — — — 431 — 2,418 — 9,487 9,709 — — 7,580 10,240 — — — 8,311 125 — 114 3,682 5,540 — — — — — 27,852 21,702 8,083 — 159,299 316,136 220,308 130,937 194,299 366,279 8,596 1,395,854 96,819 144,329 204,077 205,046 160,612 159,742 350,502 1,321,127 — 350 109 — — — 726 — 33 — 1,520 — 720 896 1,762 — — — 715 — 966 1,452 9,671 — 479 100 2,198 2,798 2,002 16,505 — — 97,278 145,055 205,630 208,424 161,327 171,831 353,083 1,342,628 214,774 146,511 103,769 60,782 39,692 53,758 204,304 823,590 71 154 317 — 946 41 4,595 — 965 3,016 3,199 — 5,612 1,609 2,292 — 67 553 2,074 — 635 3,239 704 — 209 764 81 20 8,505 9,376 13,262 20 215,316 152,093 110,949 70,295 42,386 58,336 205,378 854,753 106 (In thousands) Consumer Risk Ratings: Pass Special Mention Substandard Substandard Impaired Doubtful Total Paycheck Protection Program Risk Ratings: Pass Total Consolidated Risk Ratings: Pass Special Mention Substandard Substandard Impaired Doubtful1 Total 2020 2019 2018 2017 2016 Prior Revolving Total December 31, 2020 46,476 43,143 30,433 18,937 21,880 9,488 15,089 185,446 58 — 7 — 27 — 50 — 14 — 193 — 41 42 24 — 42 4 329 — 21 151 183 — 1,854 228 21 — 2,057 425 807 — 46,541 43,220 30,640 19,044 22,255 9,843 17,192 188,735 566,961 566,961 — — — — — — — — — — — — 566,961 566,961 1,302,389 898,213 741,734 562,336 553,531 885,576 628,070 5,571,849 6,108 504 433 — 3,507 41 10,940 — 19,722 12,725 5,659 — 13,953 7,256 5,477 — 14,820 10,823 3,243 — 7,235 14,083 21,211 — 2,544 1,092 2,104 20 67,889 46,524 49,067 20 $ 1,309,434 $ 912,701 $ 779,840 $ 589,022 $ 582,417 $ 928,105 $ 633,830 $ 5,735,349 1Loans classified as doubtful are fully reserved as of December 31, 2020.

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 provided financially impacted borrowers with loan accommodations, primarily consisting of payment deferrals of up to six months. At its peak, loans on deferral represented $1.1 billion, or 21% of total non-PPP loans. As the year progressed, the large majority of these borrowers successfully resumed making contractual payments, and the level of loans with accommodations dropped to $74.1 million, or 1% of total non-PPP loans, at December 31, 2020. Types of outstanding 107 accommodations at December 31, 2020 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.

During the year ended December 31, 2020, there were no defaults on loans that had been modified in TDRs within the preceding twelve months. There were four defaults totaling $3.2 million of loans modified in TDRs within the twelve months preceding December 31, 2019. During the twelve months ended December 31, 2018, there were no defaults on loans modified in TDRs 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, $0.1 million, $0.1 million, and $0.2 million for the years ended December 31, 2020, 2019, and 2018, respectively, was included in interest income and represents the change in present value attributable to the passage of time. 109 Note F - Allowance for Credit Losses Activity in the allowance for credit losses is summarized as follows: December 31, 2020 Impact of Adoption of ASC 326 Beginning Balance Initial Allowance on PCD Loans Acquired During the Period (In thousands) Provision for Credit Losses1 Charge- Offs Recoveries TDR Allowance Adjustments Ending Balance Construction and land development $ 1,842 $ 1,479 $ 87 $ 1,399 $ — $ 114 $ (1) $ 4,920 Commercial real estate - owner occupied Commercial real estate - non-owner occupied Residential real estate Commercial and financial Consumer Paycheck Protection Program 5,361 7,863 7,667 9,716 2,705 — 80 1,161 3,632 (310) 9,341 5,787 3,677 862 — 2,236 18,966 124 2,643 28 — 3,840 8,329 1,613 — (177) (240) (7,091) (2,024) — 18 37 350 1,416 316 — (74) 9,868 — 38,266 (28) 17,500 — 18,690 (11) — 3,489 — Total $ 35,154 $ 21,226 $ 6,279 $ 37,779 $ (9,842) $ 2,251 $ (114) $ 92,733 1In addition, the Company recorded a $0.4 million provision to establish a valuation allowance on accrued interest receivable.

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. 110 As of December 31, 2020, the Company utilized Moody’s most recent “U.S. Macroeconomic Outlook Baseline” scenario and considered the significant uncertainty associated with the assumptions in the Baseline scenario, including the potential resurgence of virus infections in Florida and other states, and the resulting potential decline in consumer spending and financial implications for businesses. The Company also considered the amount and availability of fiscal stimulus, including programs offered under the CARES Act and other potential future government programs and actions. Outcomes in any or all of these factors could differ from the Baseline scenario, and the Company incorporated qualitative considerations reflecting uncertainty of economic conditions, the possibility that the characteristics of the economic downturn could be sustained over a more extended period, and for additional dimensions of risk not captured in the quantitative model. After the adoption of ASC Topic 326 on January 1, 2020, changes in the allowance for credit losses during the year were largely the result of deterioration in economic conditions due to the COVID-19 pandemic, including higher unemployment and losses of business revenue, and expectations as to the severity and duration of the economic recession. In the Construction and Land Development segment, the increase in reserves during the year was affected by both the outlook for commercial real estate valuations, and qualitative adjustments relating to the uncertainty of economic conditions. 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 increase in reserves reflects both the impact of higher loan balances, higher unemployment levels, and lower forecasted commercial real estate valuations. 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 increase in reserves reflects higher unemployment levels and deterioration in corporate profits over the forecast period. 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 increase in reserves reflects higher unemployment, partially offset by lower loan balances and continued strength in the Florida housing market. 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 increase in reserves reflects an increased proportion of working capital lines compared to loans secured by business assets, higher overall balances, and recessionary conditions. 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. A decrease in the reserve is attributed to lower loan balances, partially offset by higher unemployment and recessionary conditions. Balances outstanding under the Paycheck Protection Program are guaranteed by the U.S. government and have not been assigned a reserve. 111 The allowance for credit losses is composed of specific allowances for loans individually evaluated and general allowances for loans grouped into loan pools based on similar characteristics, which are collectively evaluated. The Company’s loan portfolio and related allowance at December 31, 2020 and 2019 is shown in the following tables.

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 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 is 7.5 years. 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. As of December 31, 2020, the interest rate floors have a fair value of $1.0 million and are recorded in other assets in the consolidated balance sheet. Over the next twelve months the 112 Company expects to reclassify $0.2 million from accumulated other comprehensive income into interest income related to these agreements.

The trust preferred securities may be redeemed without penalty, upon approval of the Federal Reserve or upon occurrence of certain events affecting their tax or regulatory capital treatment. Distributions on the trust preferred securities are payable quarterly in March, June, September, and December of each year. The proceeds of the offering of trust preferred securities and common equity securities were used by SBCF Capital Trust I and SBCF Statutory Trust II to purchase the $41.2 million junior subordinated deferrable interest notes issued by the Company, and by SBCF Statutory Trust III to purchase the $12.4 million junior subordinated deferrable interest notes issued by the Company, all of which have terms substantially similar to the trust preferred securities. The Company has the right to defer payments of interest on the notes at any time or from time to time at the Company's election. Interest can be deferred for a period not longer than five years. If the Company elects to defer interest, it may not, with certain exceptions, declare or pay any dividends or distributions on its capital stock or purchase or acquire any of its capital stock. As of December 31, 2020, 2019 and 2018, all interest payments on trust preferred securities were current. The Company has entered into agreements to guarantee the payments of distributions on the trust preferred securities and payments of redemption of the trust preferred securities. Under these agreements, the Company also agrees, on a subordinated basis, to pay expenses and liabilities of the Trusts other than those arising under the trust preferred securities. The obligations of the Company under the junior subordinated notes, the trust agreement establishing the Trusts, the guarantees and agreements as to expenses and liabilities, in aggregate, constitute a full and conditional guarantee by the Company of the Trusts' obligations under the trust preferred securities. Note K - Employee Benefits and Stock Compensation The Company’s defined contribution plan covers substantially all employees after one year of service and includes a matching benefit for employees who can elect to defer a portion of their compensation. In addition, amounts of compensation contributed by employees are matched on a percentage basis under the plan. The Company's contributions to this plan charged to operations were $2.8 million in 2020, $2.4 million in 2019, and $2.1 million in 2018. The Company, through its Compensation and Governance Committee of the board of directors (the “Compensation Committee”), offers equity compensation to employees and non-employee directors of Seacoast and Seacoast Bank in the form 115 of various share-based awards, including stock options, restricted stock awards (“RSAs”), or restricted stock units (“RSUs”). The awards may vest over time, have certain performance based criteria, or both. Stock options are granted with an exercise price at least equal to the market price of the Company’s stock at the date of grant. The fair value of options granted is estimated on the date of grant using the Black-Scholes option-pricing model. Compensation cost is amortized on a straight-line basis over the vesting period. Vesting is determined by the Compensation Committee at the time of grant, generally over five years. The options have a maximum term of ten years. The fair value of RSAs and RSUs are estimated based on the price of the Company’s common stock on the date of grant. Compensation cost is measured straight-line for RSAs and ratably for RSUs over the vesting period of the awards and reversed for awards which are forfeited due to unfulfilled service or performance criteria. To the extent the Company has treasury shares available, stock options exercised or stock grants awarded may be issued from treasury shares. If treasury shares are insufficient, the Company can issue new shares. Vesting of share-based awards is immediately accelerated on death or disability of the recipient. The Compensation Committee may, at its discretion, accelerate vesting upon retirement (including a voluntary termination of employment at age 55) for those employees with five or more years of service with the Company, or upon the event of a change-in-control. Awards are currently granted under the Seacoast 2013 Incentive Plan (“2013 Plan”), which shareholders approved on May 23, 2013 and has been twice amended to increase the number of authorized shares for issuance thereunder to 4,250,000. The 2013 Plan expires on May 26, 2025. Approximately 535,000 shares remain available for issuance as of December 31, 2020.

These items are recorded as Accumulated Other Comprehensive Income in the shareholders' equity section of the consolidated balance sheet. In 2020, unrealized gains of $26.3 million resulted in a deferred tax liability of $5.9 million. In 2019, unrealized gains of $5.7 million resulted in a deferred tax liability of $1.2 million. At December 31, 2020, the Company's net deferred tax assets (“DTAs”) of $23.6 million consisted of approximately $18.0 million of net U.S. federal DTAs and $5.6 million of net state DTAs. Management assesses the necessity of a valuation allowance recorded against DTAs at each reporting period. The determination of whether a valuation allowance for net DTAs is appropriate is subject to considerable judgment and requires an evaluation of all positive and negative evidence. Based on an assessment of all of the evidence, including favorable trending in asset quality and certainty regarding the amount of future taxable income that the Company forecasts, management concluded that it was more likely than not that its net DTAs will be realized based upon future taxable income. Management's confidence in the realization of projected future taxable income is based upon analysis of the Company's risk profile and its trending financial performance, including credit quality. The Company believes it can reasonably predict future results of operations that result in taxable income at sufficient levels over the future period of time that the Company has available to realize its net DTA. A valuation allowance could be required in future periods based on the assessment of positive and negative evidence. Management's conclusion at December 31, 2020 that it is more likely than not that the net DTAs of $23.6 million will be realized is based upon estimates of future taxable income that are supported by internal projections which consider historical performance, various internal estimates and assumptions, as well as certain external data, all of which management believes to be reasonable although inherently subject to judgment. If actual results differ significantly from the current estimates of future taxable income, even if caused by adverse macro-economic conditions, a valuation allowance may need to be recorded for some or all of the Company's DTAs. The establishment of a DTA valuation allowance could have a material adverse effect on the Company's financial condition and results of operations. 121 Management expects to realize the $23.6 million in net DTAs well in advance of the statutory carryforward period. At December 31, 2020, approximately $2.9 million of DTAs relate to federal net operating losses which will expire in annual installments beginning in 2029 through 2032. Additionally, $1.3 million of the DTAs relate to state net operating losses which will expire in annual installments beginning in 2029 through 2034. Remaining DTAs are not related to net operating losses or credits and therefore, have no expiration date. The Company recognizes interest and penalties, as appropriate, as part of the provisioning for income taxes. No interest or penalties were accrued at December 31, 2020. In accordance with ASC Topic 718, Compensation – Stock Compensation, the Company recognized $0.1 million, $0.8 million and $1.1 million in 2020, 2019, and 2018, respectively, of discrete tax benefits related to share-based compensation. In accordance with ASC Topic 323, Investments-Equity Method and Joint Ventures, amortization of the Company's low-income housing credit investments of $0.9 million, $0.9 million and $1.0 million has been reflected as income tax expense for the years ended December 31, 2020, 2019, and 2018, respectively. The amount of affordable housing tax credits, amortization and tax benefits recorded as income tax expense for the year ended December 31, 2020 were $0.8 million, $0.9 million, and $0.2 million, respectively. The amount of affordable housing tax credits, amortization and tax benefits recorded as income tax expense for the year ended December 31, 2019 were $0.8 million, $0.9 million and $0.2 million, respectively. The amount of affordable housing tax credits, amortization and tax benefits recorded as income tax expense for the year ended December 31, 2018 were $0.8 million, $1.0 million and $0.2 million, respectively. The carrying value of the investments in affordable housing credits is $16.4 million and $7.4 million at December 31, 2020 and 2019, respectively, of which $9.9 million and $0.5 million, respectively, is unfunded. The Company has no unrecognized income tax benefits or provisions due to uncertain income tax positions. No federal or state income tax return examinations are currently in process. The Company does not expect to record or realize any material unrecognized tax benefits during 2021. The following are the major tax jurisdictions in which the Company operates and the earliest tax year, exclusive of the impact of the net operating loss carryforwards, subject to examination: Jurisdiction United States of America Florida Tax Year 2017 2017 In September 2019, the State of Florida announced a reduction in the corporate income tax rate from 5.5% to 4.458% for the years 2019, 2020 and 2021. This change resulted in additional income tax expense of $1.1 million upon the write down in the third quarter of 2019 of deferred tax assets affected by the change, offset by a $0.4 million benefit upon adjusting the year-to- date provision to the new statutory tax rate. As a result of the adoption of ASC 326 - Credit Losses on January 1, 2020, the tax impact relating to the incremental allowance for expected credit losses on loans held at amortized cost has been reflected as a credit to retained earnings to reflect the tax impact of increased credit reserves. Accordingly, $5.5 million of such impact has been reflected as an income tax credit and deferred tax asset on the Company's Consolidated Statements of Financial Condition. On March 27, 2020, the CARES Act was enacted, and Section 2303(b) of this act provided the Company with an opportunity to carry back net operating losses arising from 2018, 2019 and 2020 to the prior five tax years. Such NOLs were previously valued at the current federal corporate income tax rate of 21%. However, the provisions of the CARES Act provide for NOL carryback claims to be calculated based on a rate of 35%, which was the federal corporate tax rate in effect for many of the carryback years. Consequently, for the year ended December 31, 2020, the Company filed amended tax returns and has recorded the resulting benefit reflecting taxes recoverable at the 35% tax rate. This resulted in the recognition of an additional $0.4 million income tax benefit on the Company's Consolidated Statements of Income. 122 For the Year Ended December 31, 2019 2018 2020 $ $ $ 9,429 $ 13,711 7,507 14,696 690 685 3,561 10,056 60,335 1,235 61,570 $ 88,539 15,544 19,053 2,984 14,150 5,874 4,833 9,167 1,268 5,857 2,263 185 15,835 185,552 $ 11,529 $ 13,399 6,352 6,490 1,054 2,472 3,674 10,545 55,515 1,217 56,732 $ 73,829 13,697 15,077 2,958 14,284 6,245 4,161 8,553 881 5,826 51 — 15,177 160,739 $ 11,198 12,335 5,915 4,682 1,398 2,474 4,291 8,352 50,645 (623) 50,022 71,111 12,945 16,374 2,481 13,394 6,744 5,085 9,961 2,195 4,300 461 — 17,222 162,273 Note N - Noninterest Income and Expenses Details of noninterest income and expense are as follows: (In thousands) Noninterest Income Service charges on deposit accounts Interchange income Wealth management income Mortgage banking fees Marine finance fees SBA gains BOLI income Other income Securities gains (losses), net Total Noninterest Income Noninterest Expenses Salaries and wages Employee benefits Outsourced data processing costs Telephone and data lines Occupancy Furniture and equipment Marketing Legal and professional fees FDIC assessments Amortization of intangibles Foreclosed property expense and net loss on sale Provision for credit losses on unfunded commitments Other Total Noninterest Expenses 123 Note O - Shareholders’ Equity Required Regulatory Capital The Company is subject to various regulatory capital requirements administered by the Federal banking agencies. Failure to meet the minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by the regulators, which could have a direct material impact on the financial statements. These requirements involve quantitative measures of assets, liabilities and certain off-balance sheet items calculated pursuant to regulatory guidance. The Company's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company to maintain minimum amounts and ratios of total, Tier 1 capital and common equity Tier 1 capital to risk-weighted assets and of Tier 1 capital to average assets, all as defined in the regulations. At December 31, 2020 and 2019, the Company and Seacoast Bank, its wholly-owned banking subsidiary, were both considered “well capitalized” based on the applicable U.S. regulatory capital ratio requirements as reflected in the table below: (Dollars in thousands) Seacoast Banking Corporation of Florida (Consolidated) At December 31, 2020: Minimum to meet “Well Capitalized” Requirements Minimum for Capital Adequacy Purpose1 Amount Ratio Amount Ratio Amount Ratio Total Risk-Based Capital Ratio (to risk-weighted assets) $ 1,029,455 18.51% Tier 1 Capital Ratio (to risk-weighted assets) Common Equity Tier 1 Capital Ratio (to risk-weighted assets) Leverage Ratio (to adjusted average assets) 970,594 17.46 899,225 16.17 970,594 11.92 At December 31, 2019: Total Risk-Based Capital Ratio (to risk-weighted assets) $ 860,934 15.71% Tier 1 Capital Ratio (to risk-weighted assets) Common Equity Tier 1 Capital Ratio (to risk-weighted assets) Leverage Ratio (to adjusted average assets) 825,640 15.06 754,555 13.77 825,640 12.20 n/a n/a n/a n/a n/a n/a n/a n/a n/a $ 444,839 ≥ 8.00% n/a n/a n/a 333,629 ≥ 250,222 ≥ 325,690 ≥ 6.00 4.50 4.00 n/a $ 438,506 ≥ 8.00% n/a n/a n/a 328,880 ≥ 246,660 ≥ 270,788 ≥ 6.00 4.50 4.00 Seacoast National Bank (A Wholly Owned Bank Subsidiary) At December 31, 2020: Total Risk-Based Capital Ratio (to risk-weighted assets) $ 956,592 17.21% $ 555,772 ≥ 10.00% $ 444,617 ≥ 8.00% Tier 1 Capital Ratio (to risk-weighted assets) Common Equity Tier 1 Capital Ratio (to risk-weighted assets) Leverage Ratio (to adjusted average assets) 897,731 16.15 897,727 16.15 897,731 11.03 444,617 361,252 406,904 ≥ ≥ ≥ 8.00 6.50 5.00 333,463 ≥ 250,097 ≥ 325,523 ≥ 6.00 4.50 4.00 At December 31, 2019: Total Risk-Based Capital Ratio (to risk-weighted assets) $ 804,058 14.68% $ 547,440 ≥ 10.00% $ 437,952 ≥ 8.00% Tier 1 Capital Ratio (to risk-weighted assets) Common Equity Tier 1 Capital Ratio (to risk-weighted assets) 768,764 14.04 768,764 14.04 437,952 355,836 ≥ ≥ 8.00 6.50 328,464 ≥ 246,348 ≥ Leverage Ratio (to adjusted average assets) 270,230 ≥ 1Excludes the Basel III capital conservation buffer of 2.5%, which if not exceeded may constrain dividends, equity repurchases and compensation. 768,764 337,787 11.38 5.00 ≥ 6.00 4.50 4.00 n/a - not applicable Common Stock The Company has reserved 300,000 common shares for issuance in connection with an employee stock purchase plan and 1,000,000 common shares for issuance in connection with an employee profit sharing plan.

The Company implemented a dividend reinvestment plan during 2007, and issued no shares from treasury stock under this plan during 2020 or 2019. 124 In December, 2020, the Company's Board of Directors authorized the Company to repurchase up to $100 million of its shares of outstanding common stock. The amount and timing of repurchases, if any, will be based on a variety of factors, including share acquisition price, regulatory limitations, market conditions and other factors. The Company has made no repurchases under the program.

Management presently believes that none of the legal proceedings to which it is a party are likely to have a materially adverse effect on the Company’s consolidated financial condition, or operating results or cash flows. The Company's subsidiary bank is party to financial instruments with off balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit, and limited partner equity commitments. The subsidiary bank’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contract or notional amount of those instruments. The subsidiary bank uses the same credit policies in making commitments and standby letters of credit as they do for on balance sheet instruments. 126 Unfunded commitments for the Company as of: (In thousands) Contract or Notional Amount December 31, 2020 2019 Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $ 1,548,482 $ 1,018,020 Standby letters of credit and financial guarantees written: Secured Unsecured Unfunded limited partner equity commitment 11,167 1,197 13,073 663 21,390 6,011 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Commitments include home equity lines, commercial and consumer lines of credit and construction loans. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The subsidiary bank evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the bank upon extension of credit, is based on management's credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, equipment, and commercial and residential real estate. Standby letters of credit are conditional commitments issued by the subsidiary bank to guarantee the performance of a customer to a third party. These instruments have fixed termination dates and most end without being drawn; therefore, they do not represent a significant liquidity risk. Those guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing, and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The subsidiary bank holds collateral supporting these commitments for which collateral is deemed necessary. Collateral held for secured standby letters of credit at December 31, 2020 and 2019 totaled $12.4 million and $13.2 million, respectively. Unfunded limited partner equity commitments at December 31, 2020 totaled $21.4 million that the Company has committed to small business investment companies under the SBIC Act to be used to provide capital to small businesses and entities that provide low income housing tax credits. 127 — — — 6,906 12,678 — — — — 3,704 12,149 — Note R - Fair Value Under ASC Topic 820, fair value measurements for items measured at fair value on a recurring and nonrecurring basis at December 31, 2020 and December 31, 2019 included: Fair Value Measurements Quoted Prices in Active Markets for Identical Assets Level 1 Significant Other Observable Inputs Level 2 Significant Other Unobservable Inputs Level 3 (In thousands) At December 31, 2020 Financial Assets Available-for-sale debt securities1 Derivative financial instruments2 Loans held for sale2 Loans3 Other real estate owned4 Equity securities5 Financial Liabilities $ 1,398,157 $ 101 $ 1,398,056 $ 14,343 68,890 8,806 12,750 6,530 — — — — 6,530 14,343 68,890 1,900 72 — Derivative financial instruments2 $ 13,339 $ — $ 13,339 $ At December 31, 2019 Financial Assets Available-for-sale debt securities1 Loans held for sale2 Loans3 Other real estate owned4 Equity securities5 $ 946,855 $ 100 $ 946,755 $ 20,029 5,123 12,390 6,392 — — — 6,392 20,029 1,419 241 — 1See “Note D - Securities” for further detail of fair value of individual investment categories. 2Recurring fair value basis determined using observable market data. 3See “Note E - Loans”. Nonrecurring fair value adjustments to collateral-dependent loans reflect full or partial write-downs that are based on current appraised values of the collateral in accordance with ASC Topic 310. 4Fair value is measured on a nonrecurring basis in accordance with ASC Topic 360. 5An investment in shares of a mutual fund that invests primarily in CRA-qualified debt securities, reported at fair value in Other Assets. 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 credit worthiness of the 128 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 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 contractual terms of the loan in accordance with Company policy on loans held for investment. None of the loans are 90 days or more past due or on nonaccrual as of December 31, 2020 and 2019. The aggregate fair value and contractual balance of loans held for sale as of December 31, 2020 and 2019 is as follows: (In thousands) Aggregate fair value Contractual balance Excess December 31, 2020 2019 $ 68,890 $ 66,415 2,475 20,029 19,445 584 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. For these loans 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 December 31, 2020 the range of capitalization rates utilized to determine fair value of the underlying collateral averaged approximately 7.3%. 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 $8.8 million with a specific reserve of $7.7 million at December 31, 2020, compared to $5.1 million with a specific reserve of $2.9 million at December 31, 2019. For loans classified as level 3, the changes included additions of $11.9 million offset by $8.7 million in paydowns and charge- offs during the twelve months ended December 31, 2020. 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 level 2. 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. Loans of $4.5 million migrated to OREO during the twelve months ended December 31, 2020 and were classified as level 3. Other changes in 2020 to OREO loans classified as level 3 include sales of $4.9 million and charge-offs of $1.6 million, offset by additions of $2.6 million during the twelve months ended December 31, 2020. 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 quarter valuation process. There were no such transfers during the twelve months ended December 31, 2020 and 2019. 129 The carrying amount and fair value of the Company's other significant financial instruments that were not disclosed previously in the balance sheet and for which carrying amount is not fair value as of December 31, 2020 and December 31, 2019 is as follows: (In thousands) At December 31, 2020 Financial Assets Quoted Prices in Active Markets for Identical Assets Level 1 Significant Other Observable Inputs Level 2 Significant Other Unobservable Inputs Level 3 Carrying Amount Held-to-maturity debt securities1 $ 184,484 $ — $ 192,179 $ Time deposits with other banks Loans, net Financial Liabilities Deposits Subordinated debt At December 31, 2019 Financial Assets 750 5,633,810 6,932,561 71,365 — — — — 762 — — 58,227 Held-to-maturity debt securities1 $ 261,369 $ — $ 262,213 $ Time deposits with other banks Loans, net Financial Liabilities Deposits Federal Home Loan Bank (“FHLB”) borrowings Subordinated debt 3,742 5,158,127 5,584,753 315,000 71,085 — — — — — — — — — 64,017 — — 5,686,019 6,936,097 — — 3,744 5,139,491 5,584,621 314,995 — 1See “Note D - Securities” for further detail of recurring fair value basis 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 agreement to repurchase. 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 December 31, 2020 and December 31, 2019: Loans: Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, mortgage, etc. Each loan category is further segmented into fixed and adjustable rate interest terms and by 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.

Determining fair values of assets and liabilities, especially the loan portfolio, core deposit intangibles, and deferred taxes, is a complicated process involving significant judgment regarding methods and assumptions used to calculate estimated fair values.

The factors we considered to identify loans as PCI loans were all acquired loans that were nonaccrual, 60 days or more past due, designated as TDR, graded “special mention” or “substandard.” These loans were then evaluated to determine estimated fair values as of the acquisition date. As required by generally accepted accounting principles, the Company accounted for these loans pursuant to ASC Topic 310-30 at the time of acquisition and until the adoption of ASC Topic 326 on January 1, 2020. The table below summarizes the total contractually required principal and interest cash payments, management’s estimate of expected total cash payments and fair value of the loans as of October 19, 2018 for purchased credit-impaired loans. Contractually required principal and interest payments have been adjusted for estimated prepayments.

These loans were then evaluated to determine estimated fair values as of the acquisition date. Although no specific credit deficiencies were identifiable, we believe there is an element of risk as to whether all contractual cash flows will be eventually received. Factors that were considered included the economic environment both nationally and locally as well as the real estate market particularly in Florida. 135 The Company believes the deposits assumed from the acquisition have an intangible value. In determining the valuation amount, deposits were analyzed based on factors such as type of deposit, deposit retention, interest rates and age of deposit relationships. Acquisition Costs Acquisition costs included in the Company’s income statement for the years ended December 31, 2020, 2019 and 2018 are $9.1 million, $1.0 million, and $9.7 million, respectively.

Controls and Procedures (a) Evaluation of Disclosure Controls and Procedures The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including the Company's Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating disclosure controls and procedures, as defined in SEC Rule 13a-15 under the Exchange Act, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In connection with the preparation of this Annual Report on Form 10-K, as of the end of the period covered by this report, an evaluation was performed, with the participation of the CEO and CFO, of the effectiveness of the Company's disclosure controls and procedures, as required by Rule 13a-15 of the Exchange Act. Based upon that evaluation, the CEO and CFO concluded that the disclosure controls and procedures were effective as of the end of the period covered by this report. (b) Management’s Report on Internal Control over Financial Reporting Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. Our internal control system was designed to provide reasonable assurance to management and the board of directors regarding the reliability of financial reporting and the preparation of financial statements for external purposes. Management conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2020. This assessment was based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework 2013. Based on this assessment, management believes that, as of December 31, 2020, the Company's internal control over financial reporting was effective. 136 The Company's independent registered public accounting firm, Crowe LLP, has issued an audit report on our internal control over financial reporting which is included herein. (c) Change in Internal Control Over Financial Reporting During the three months ended December 31, 2020, there were no changes in the internal control over financial reporting that occurred or that have materially affected, or are reasonably likely to materially affect, the internal control over financial reporting.

DESCRIPTION OF CAPITAL STOCK The following descriptions are summaries of the material terms of our amended and restated articles of incorporation and amended and restated bylaws and include all material information with respect to our capital stock. Reference is made to the more detailed provisions of the amended and restated articles of incorporation and amended and restated bylaws, which are filed as exhibits to this Annual Report on Form 10-K and are incorporated by reference herein. Common Stock General The following description of shares of Seacoast’s common stock, par value $0.10 per share, is a summary only and is subject to applicable provisions of the Florida Business Corporation Act, as amended, or the FBCA, and to Seacoast’s amended and restated articles of incorporation, as amended, and its amended and restated bylaws. Seacoast’s articles of incorporation provide that it may issue up to 120 million shares of common stock, par value of $0.10 per share. Seacoast common stock is listed on the NASDAQ Global Select Market under the symbol “SBCF.” Voting Rights Each outstanding share of Seacoast’s common stock entitles the holder to one vote on all matters submitted to a vote of shareholders, including the election of directors. The holders of Seacoast common stock possess exclusive voting power, except as otherwise provided by law or by articles of amendment establishing any series of Seacoast preferred stock. There is no cumulative voting in the election of directors, which means that the holders of a plurality of Seacoast’s outstanding shares of common stock can elect all of the directors then standing for election. When a quorum is present at any meeting, questions brought before the meeting will be decided by the vote of the holders of a majority of the shares present and voting on such matter, whether in person or by proxy, except when the meeting concerns matters requiring the vote of the holders of a majority of all outstanding shares under applicable Florida law. Seacoast’s articles of incorporation provide certain anti- takeover provisions that require super-majority votes, which may limit shareholders’ rights to effect a change in control as described under the section below entitled “Anti-Takeover Effects of Certain articles of incorporation Provisions.” Dividends, Liquidation and Other Rights Holders of shares of common stock are entitled to receive dividends only when, as and if approved by Seacoast’s board of directors from funds legally available for the payment of dividends. Seacoast’s shareholders are entitled to share ratably in its assets legally available for distribution to its shareholders in the event of Seacoast’s liquidation, dissolution or winding up, voluntarily or involuntarily, after payment of, or adequate provision for, all of our known debts and liabilities and of any preferences of any series of our preferred stock that may be outstanding in the future. These rights are subject to the preferential rights of any series of Seacoast’s preferred stock that may then be outstanding. Holders of shares of Seacoast common stock have no preference, conversion, exchange, sinking fund or redemption rights and have no preemptive rights to subscribe for any of our securities. Seacoast’s board of directors, under its articles of incorporation, may issue additional shares of its common stock or rights to purchase shares of its common stock without shareholder approval. Restrictions on Ownership The Bank Holding Company Act requires any “bank holding company,” as defined in the Bank Holding Company Act, to obtain the approval of the Federal Reserve prior to the acquisition of 5% or more of our common shares. Any person, other than a bank holding company, is required to obtain prior approval of the Federal Reserve to acquire 10% or more of our common shares under the Change in Bank Control Act. Any holder of 25% or more of our common shares, or a holder of 5% or more if such holder otherwise exercises a “controlling influence” over us, is subject to regulation as a bank holding company under the Bank Holding Company Act. Certain provisions included in our amended and restated articles of incorporation and bylaws, as described further below, as well as certain provisions of the Florida Business Corporation Act and federal law, may discourage, delay or prevent potential acquisitions of control of us, particularly when attempted in a transaction that is not negotiated directly with, and approved by, our board of directors, despite possible benefits to our shareholders. Transfer Agent and Registrar The transfer agent and registrar for Seacoast common stock is Continental Stock Transfer and Trust Company. Anti-Takeover Effects of Certain Articles of Incorporation Provisions Seacoast’s articles of incorporation contain certain provisions that make it more difficult to acquire control of it by means of a tender offer, open market purchase, a proxy fight or otherwise. These provisions are designed to encourage persons seeking to acquire control of Seacoast to negotiate with its directors. Seacoast believes that, as a general rule, the interests of its shareholders would be best served if any change in control results from negotiations with its directors. Seacoast’s articles of incorporation provide for a classified board to which approximately one-third of its board of directors is elected each year at its annual meeting of shareholders. Accordingly, Seacoast’s directors serve three-year terms rather than one-year terms. The classification of Seacoast’s board of directors has the effect of making it more difficult for shareholders to change the composition of its board of directors. At least two annual meetings of shareholders, instead of one, will generally be required to effect a change in a majority of Seacoast’s board of directors. Such a delay may help ensure that its directors, if confronted by a shareholder attempting to force a proxy contest, a tender or exchange offer, or an extraordinary corporate transaction, would have sufficient time to review the proposal as well as any available alternatives to the proposal and to act in what they believe to be the best interests of Seacoast’s shareholders. The classification provisions apply to every election of directors, however, regardless of whether a change in the composition of Seacoast’s board of directors would be beneficial to Seacoast and its shareholders and whether or not a majority of its shareholders believe that such a change would be desirable. The classification of Seacoast’s board of directors could also have the effect of discouraging a third party from initiating a proxy contest, making a tender offer or otherwise attempting to obtain control of Seacoast, even though such an attempt might be beneficial to Seacoast and its shareholders. The classification of Seacoast’s board of directors could thus increase the likelihood that incumbent directors will retain their positions. In addition, because the classification of Seacoast’s board of directors may discourage accumulations of large blocks of its stock by purchasers whose objective is to take control of Seacoast and remove a majority of its board of directors, the classification of its board of directors could tend to reduce the likelihood of fluctuations in the market price of its common stock that might result from accumulations of large blocks of its common stock for such a purpose. Accordingly, Seacoast’s shareholders could be deprived of certain opportunities to sell their shares at a higher market price than might otherwise be the case. Seacoast’s articles of incorporation require the affirmative vote of the holders of not less than two-thirds of all the shares of its stock outstanding and entitled to vote generally in the election of directors in addition to the votes required by law or elsewhere in the articles of incorporation, the bylaws or otherwise, to approve: (a) any sale, lease, transfer, purchase and assumption of all or substantially all of its consolidated assets and/or liabilities, (b) any merger, consolidation, share exchange or similar transaction, or any merger of any significant subsidiary, into or with another person, or (c) any reclassification of securities, recapitalization or similar transaction that has the effect of increasing other than pro rata with the other shareholders, the proportionate amount of shares that is beneficially owned by an Affiliate (as defined in Seacoast’s articles of incorporation). Any business combination described above may instead be approved by the affirmative vote of a majority of all the votes entitled to be cast on the plan of merger if such business combination is approved and recommended to the shareholders by (x) the affirmative vote of two-thirds of Seacoast’s board of directors, and (y) a majority of the Continuing Directors (as defined in Seacoast’s articles of incorporation). Seacoast’s articles of incorporation also contain additional provisions that may make takeover attempts and other acquisitions of interests in it more difficult where the takeover attempt or other acquisition has not been approved by its board of directors. These provisions include: • • • • A requirement that any change to Seacoast’s articles of incorporation relating to the structure of its board of directors, certain anti-takeover provisions and shareholder proposals must be approved by the affirmative vote of holders of two- thirds of the shares outstanding and entitled to vote; A requirement that any change to Seacoast’s bylaws, including any change relating to the number of directors, must be approved by the affirmative vote of either (a) (i) two-thirds of its board of directors, and (ii) a majority of the continuing directors (as defined in Seacoast’s articles of incorporation) or (b) (i) two-thirds of the shares entitled to vote generally in the election of directors and (ii) an Independent Majority of Shareholders. An “Independent Majority of Shareholders” means the majority of the outstanding voting shares that are not beneficially owned or controlled, directly or indirectly by a related party. For these purposes, a “related party” means a beneficial owner of 5% or more of the voting shares, or any person who is an affiliate of Seacoast and at any time within five years was the beneficial owner of 5% or more of Seacoast’s then outstanding shares; provided, however, that this provision shall not include (i) any person who is the beneficial owner of more than 5% of Seacoast’s shares on February 28, 2003, (ii) any plan or trust established for the benefit of Seacoast’s employees generally, or (iii) any subsidiary of Seacoast that holds shares in a fiduciary capacity, whether or not it has the authority to vote or dispose of such securities; A requirement that shareholders may call a meeting of shareholders on a proposed issue or issues only upon the receipt by Seacoast from the holders of 50% of all shares entitled to vote on the proposed issue or issues of signed and dated written demands for the meeting describing the purpose for which it is to be held; and A requirement that a shareholder wishing to submit proposals for a shareholder vote or nominate directors for election comply with certain procedures, including advanced notice requirements. Seacoast’s articles of incorporation provide that, subject to the rights of any holders of its preferred stock to act by written consent instead of a meeting, shareholder action may be taken only at an annual meeting or special meeting of the shareholders and may not be taken by written consent. The articles of incorporation also include provisions that make it difficult to replace directors. Specifically, directors may be removed only for cause and only upon the affirmative vote at a meeting duly called and held for that purpose upon not less than thirty days prior written notice of (i) two-thirds of the shares entitled to vote generally in the election of directors and (ii) an Independent Majority of Shareholders. In addition, any vacancies on the board of directors for any reason, and any newly created directorships resulting from any increase in the number of directors, may be filled only by the board of directors (except if no directors remain on the board, in which case the shareholders may act to fill the vacant board). Seacoast believes that the power of its board of directors to issue additional authorized but unissued shares of its common stock or preferred stock without further action by its shareholders, unless required by applicable law or the rules of any stock exchange or automated quotation system on which its securities may be listed or traded, will provide Seacoast with increased flexibility in structuring possible future financings and acquisitions and in meeting other needs that might arise. Seacoast’s board of directors could authorize and issue a class or series of stock that could, depending upon the terms of such class or series, delay, defer or prevent a transaction or a change in control that might involve a premium price for holders of Seacoast’s common stock or that its shareholders otherwise consider to be in their best interest. The Company had the following subsidiaries as of the date of this report: LIST OF SUBSIDIARIES NAME 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13.
