REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Participants and Administrator of the

Retirement Savings Plan for Employees of Seacoast National Bank

Stuart, Florida

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of the Retirement Savings Plan for Employees of Seacoast National Bank (the “Plan”) as of December 31, 2019 and 2018, and the related statement of changes in net assets available for benefits for the year ended December 31, 2019, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2019 and 2018, and the changes in net assets available for benefits for the year ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on the Plan's financial statements 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 Plan 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits 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. We believe that our audits provide a reasonable basis for our opinion.

Supplemental Information

The supplemental Schedule H, Line 4i - Schedule of Assets (Held at End of Year) as of December 31, 2019 has been subjected to audit procedures performed in conjunction with the audit of the Retirement Savings Plan for Employees of Seacoast National Bank financial statements. The supplemental schedule is the responsibility of the Plan’s management. Our audit procedures included determining whether the information presented in the supplemental schedule reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental schedule. In forming our opinion on the supplemental schedule, we evaluated whether the supplemental schedule, including their form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental schedule is fairly stated in all material respects in relation to the financial statements as a whole.

RETIREMENT SAVINGS PLAN FOR EMPLOYEES OF

SEACOAST NATIONAL BANK

NOTES TO FINANCIAL STATEMENTS

December 31, 2019 and 2018

NOTE 1 - DESCRIPTION OF PLAN

The following description of the Retirement Savings Plan for Employees of Seacoast National Bank (“the Plan”) provides only general information. Eligible employees who participate should refer to the Plan agreement for a more complete description of the Plan’s provisions.

General: The Plan is a defined contribution plan subject to the provisions of the Employee Retirement Income Security Act (“ERISA”) of 1974, as amended and was formed effective January 1, 1983. The Plan, which has subsequently been amended and restated in order to continue the qualification of the Plan under Internal Revenue Service (“IRS”) Regulations, permits employees to make salary deferrals, provide employer matching contributions and includes loan provisions. The Plan is made available to all eligible employees of Seacoast National Bank, its subsidiaries and affiliates (“the Bank” or “the Employer”) who have at least 90 days of service.

The Plan has contracted with BMO Harris Bank N.A. (“BMO”) to act as custodian under the plan and One America Retirement Services LLC (“One America”) as record keeper under the Plan and therefore BMO and One America are each a party-in-interest to the Plan. Under the contract with BMO and One America, Plan participants are offered a choice of various investment options and allowed to change their investment options daily.

Participant Accounts: Each participant’s account is credited with participant salary deferrals and an allocation of matching contributions, profit-sharing contributions and retirement contributions, if any, by the Employer, and earnings, and is charged with his or her withdrawals and an allocation of administrative expenses and losses. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account. Each participant directs the investment of their account to any of the investment options available under the Plan, which includes mutual funds, a collective trust fund and common stock of Seacoast Banking Corporation of Florida (“the Company”), the parent company of the Bank.

Participant Contributions: Each participant may voluntarily contribute to the Plan up to a maximum of 75% of annual eligible compensation. Participants can also elect to make Roth 401(k) contributions to the Plan by means of payroll deduction. Participant contributions were subject to an overall annual limitation of $19,000 for 2019. If a participant is eligible for the Plan and is age 50 or over, the participant is eligible to make an additional catch up contribution up to maximum IRS limits of $6,000 for 2019. The Plan includes an automatic contribution arrangement that applies to new participants or rehired participants. Plan participant salary deferrals less than 6% are automatically increased 1% at the beginning of each plan year until the 6% threshold is met.

Employer Contributions: The Plan was amended effective January 1, 2014 to become a safe harbor plan and provide a safe harbor match contribution. The matching contribution is subject to certain eligibility requirements as defined by the Plan and is equal to 100% of the first 3% of base compensation and 50% of the next 2% of base compensation that a participant contributes to the Plan for the year ended December 31, 2019.

On October 21, 2016, the board of directors approved an amendment to redefine eligibility for the Bank’s discretionary profit sharing contribution; effective January 1, 2017, the contribution will only be allocated to eligible participants with compensation of $75,000 or less. For the year ended December 31, 2019, there was no non-elective profit sharing contribution paid by the Bank.

Vesting: Participants are immediately vested in their voluntary contributions and the Employer matching contribution. Discretionary retirement and non-elective profit sharing contributions vest at a rate of 25% per year of service. However, if a participant retires, dies or becomes disabled the participant’s account becomes 100% vested.

Payment of Benefits: Withdrawals from the Plan may be made when the participant reaches age 59½, terminates employment, dies, becomes disabled or experiences financial hardship, as defined. Generally, vested Plan benefits not exceeding $1,000 are distributed to participants in a single lump-sum payment after employment with the Bank is terminated. If a terminated participant’s benefits exceed $1,000, the individual may elect to receive a rollover, lump sum payment or installments. If the terminated participant maintained a portion of their funds in the Company common stock, a portion of the distribution may be made in shares of common stock.

4

Notes Receivable from Participants: Participants may borrow from their fund accounts a minimum of $1,000 up to a maximum of $50,000 or 50 percent of their vested account balance, whichever is less. The loans are secured by the balance in the participant's account and bear interest at the prime rate as determined quarterly by BMO. Principal and interest are paid through payroll deductions and are paid back over a period not to exceed five years, unless the loan is for the purpose of purchasing a primary residence. For loans used to purchase a primary residence, the loan repayment period may not exceed ten years.

Forfeitures: Forfeitures are created when participants terminate participation in the Plan before becoming fully vested in the Employer’s contributions under the Plan. Forfeited amounts are used to reduce future Employer contributions or administration expenses. Remaining forfeitures at December 31, 2019 and 2018 totaled approximately $466 and $1,979, respectively. For the year ended December 31, 2019, $2,259 in forfeitures were utilized to offset expenses.

Administrative and Investment Management Fees: Loan origination fees associated with notes receivable from participants and the Plan’s record keeping, audit fees associated with annual audit of the Plan's financial statements and custodian fees are paid by the Plan and are reflected in the financial statements as administrative expenses of the Plan. Investment management fees are charged to the Plan as a reduction of investment return and included in the investment income (loss) reported by the Plan. All other expenses of the Plan are paid by the Bank.

NOTE 2 - SUMMARY OF ACCOUNTING POLICIES

The following is a summary of significant accounting policies followed by the Plan.

Basis of Accounting: The Plan’s financial statements are prepared on the accrual basis in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), and reflect management’s estimates and assumptions, such as those regarding fair value, that affect the recorded amounts.

Investment Valuation and Income Recognition: The Plan’s investments are stated at fair value. 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. See Note 4 for further discussion related to fair value measurements.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on an accrual basis. Dividends are recorded on the ex-dividend date. Net appreciation (depreciation) includes the Plan’s gains and losses on investments bought and sold as well as held during the year.

Notes Receivable from Participants: Notes receivable from participants are reported at their unpaid principal balance plus any accrued but unpaid interest, with no allowance for credit losses, as repayments of principal and interest are received through payroll deductions and the notes are collateralized by the participants' account balances.

Payment of Benefits: Benefits are recorded when paid.

Use of Estimates: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and changes therein, and disclosure of contingent assets and liabilities. Significant estimates are the valuation of investments held by the Plan. Actual results could differ from those estimates.

Risks and Uncertainties: The Plan invests in various investments including the Company’s common stock. Investments are exposed to various risks such as interest rate, market, liquidity, and credit risks. Due to the level of risk associated with certain investments and the sensitivity of certain fair value estimates to changes in valuation assumptions, it is at least reasonably possible that changes in the values of investments will occur in the near term and that such changes could materially affect participants' account balances and the amounts reported in the Statements of Net Assets Available for Benefits.

NOTE 3 - RIGHTS UPON PLAN TERMINATION

Although it has not expressed any intent to do so, the Bank has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants would become 100% vested in their Employer contributions and earnings thereon.

NOTE 4 - FAIR VALUE MEASUREMENTS

5

Fair value is the price that would be received by the Plan to sell an asset or paid by the Plan to transfer a liability in an orderly transaction between market participants on the measurement date. Fair value measurements are determined by maximizing the use of observable inputs and minimizing the use of unobservable inputs when measuring fair value. The hierarchy places the highest priority on unadjusted quoted market prices in active markets for identical assets or liabilities (level 1 inputs) and gives the lowest priority to unobservable inputs (level 3 inputs). The three levels of inputs within the fair value hierarchy are defined as follows:

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the Plan has the ability to access as of the measurement date.

Level 2: Significant other observable inputs other than level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3: Significant unobservable inputs that reflect the Plan’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

In some cases a valuation technique used to measure fair value may include inputs from multiple levels of the fair value hierarchy. The lowest level of significant input determines the placement of the entire fair value measurement in the hierarchy.

The following are descriptions of the valuation methods and assumptions used by the Plan to estimate the fair values of its investments.

Company common stock: Valued at the closing price reported on the active market on which the securities are traded (level 1 input).

Mutual funds: Valued at the daily closing price as reported by the fund. Mutual funds held by the Plan are open-end mutual funds that are registered with the U.S. Securities and Exchange Commission. These funds are required to publish their daily net asset value and to transact at that price. The mutual funds held by the Plan are deemed to be actively traded (level 1 inputs).

Stable value collective trust fund: The BMO Employee Benefit Stable Principal Fund invests in conventional and synthetic investment contracts issued by life insurance companies, banks, and other financial institutions, with the objective of maintaining safety of principal while generating a level of current income generally exceeding that of a money market fund. The fair values of participation units in the fund are based upon the daily net asset values of such fund. The net asset value is used as a practical expedient to estimate fair value. The fund maintains cash, internal cash flow and a maturity ladder of investments to offset cash withdrawals. The fund provides for daily redemptions by the Plan at reported net asset value per share, with no notification requirements. The fund managers may limit withdrawals in order to maintain sufficient liquidity.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

Investments are measured at fair value on a recurring basis, as summarized below:

	Fair Value Measurements at December 31, 2019
	Level 1		Level 2		Level 3		Total Assets
Investments in the fair value hierarchy:
Mutual funds	$	62,640,452	$	—	$	—	$	62,640,452

1In accordance with ASC 820-10, certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in these tables are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the statement of net assets available for benefits.

There were no transfers between levels during 2019 or 2018.

NOTE 5 - INCOME TAX STATUS

The IRS has determined and informed the Bank, by letter dated January 27, 2015, that the Plan is designed in accordance with the applicable sections of the Internal Revenue Code (IRC) and therefore is exempt from Federal income taxes. Although the Plan has been amended since receiving the letter, Plan management believes that the Plan is designed and being operated in compliance with the applicable requirements of the IRC. Therefore, no provision for income taxes has been included in the Plan’s financial statements.

U.S. GAAP requires plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The Plan administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2019 and 2018, there are no uncertain tax positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan administrator believes it is no longer subject to income tax examinations for years prior to 2016.

NOTE 6 - PARTY-IN-INTEREST TRANSACTIONS

Parties-in-interest are defined under Department of Labor regulations as any fiduciary of the Plan, any party rendering service to the Plan, the Employer, and certain others. The Plan holds units of a collective trust account managed by BMO Harris Bank N.A., the Plan trustee, and mutual funds managed by BMO Harris, which qualify as party-in-interest investments. The Plan’s payments of trustee fees to BMO and audit fees to Crowe LLP, the Plan's auditor, qualify as party-in-interest transactions. The Plan also holds shares of Company common stock. At December 31, 2019 and 2018, the Plan held 105,910 and 129,762 shares, respectively, of the Company’s common stock with a fair value of $3,242,910 and $3,383,276, respectively. Notes receivable from participants also reflect party-in-interest transactions. Certain administrative functions are performed by officers or employees of the Bank. No such officer or employee receives compensation from the Plan. Certain administrative expenses of the Plan are paid directly by the Bank.

NOTE 7 - SUBSEQUENT EVENT

During the first quarter of 2020, the global economy began experiencing a downturn related to the impacts of the COVID-19 global pandemic. The downturn has caused significant market volatility affecting the Plan's investments. The duration and full impact of the global pandemic to the Plan cannot be reasonably estimated at this time. 

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act"), became law in response to the COVID-19 pandemic. The CARES Act provides relief in both distribution and loan provisions for qualified participants.

Qualified Participant

The CARES Act defines a qualified participant as one who is either diagnosed with COVID-19 or their spouse or dependent is diagnosed with the virus. Additionally, a participant is qualified if they directly, not their spouse, experience an adverse financial consequence related to the virus due to being quarantined, furloughed, laid off, working a reduced schedule, or unable

7

to work due to lack of childcare.

Distributions

The CARES Act allows qualified participants to make distributions up to $100,000 from January 1, 2020 to December 31, 2020. The distributions are not subject to the early 10% distribution penalty, have no mandatory withholding at the time of distribution, and can be included in taxable income over a three year period.

Loan Provision

The CARES Act increased, for qualified participants, the amount that may be borrowed from their fund between March 27, 2020 and September 22, 2020 to a maximum of $100,000 or 100 percent of their vested balance, whichever is less. Additionally, for plan loans outstanding on or after March 27, 2020 the due date for any payments due between March 27, 2020 and December 31, 2020, can be delayed for one year. This delay is disregarded for calculating the maximum loan term of five years (see Note 1).
