Net Interest Income and Margin • Excluding both accretion on acquired loans and the effect of PPP loans, net interest margin1 in the third quarter was 3.42% compared to 3.46% in the prior quarter. • Net interest income1 totaled $63.6 million, a decrease of $3.8 million, or 6%, from the prior quarter and an increase of $2.6 million, or 4%, from the third quarter of 2019. Interest income declined by $5.1 million compared to the prior quarter, largely due to the change in the timing of fees recognized on PPP loans. The effect on net interest income was offset by a decrease of $1.3 million in interest expense. • Fees earned by Seacoast to originate PPP loans totaled $17.2 million, and are deferred and recognized as an adjustment to yield over time. At the end of the second quarter of 2020, we expected that the SBA's PPP forgiveness process would begin quickly. By the end of the third quarter of 2020, as a result of SBA delays, we have changed from the accelerated fee recognition schedule used in the second quarter of 2020, and have begun recognizing fees on a schedule aligned with the full contractual maturity of the loans. This resulted in only $0.2 million in PPP fees recognized in the third quarter of 2020, compared to $4.0 million in the second quarter of 2020. This is only a timing issue, as the remaining SBA fees will be recognized over the remaining terms of the loans with actual forgiveness events accelerating that recognition if and when those events occur. 1Calculated on a fully taxable equivalent basis using amortized cost THIRD QUARTER 2020 6
Strong Growth and Record Results in Noninterest Income Noninterest Income ($ in thousands) Adjusted Noninterest Income1 ($ in thousands) 2 3 Noninterest income increased $1.9 million sequentially to $16.9 million, and adjusted noninterest income1 increased $3.2 million to $16.9 million sequentially. Changes include: • Mortgage banking fees increased $1.7 million, or 48%, compared to the second quarter of 2020 to a record $5.3 million, as Seacoast continues to capitalize on the robust residential refinance market and strength in the Florida housing market. Seacoast’s mortgage team has adapted quickly to the heightened demand by increasing customer service level standards with realtors, refinance customers, and new home buyers, resulting in stronger performance than competitors. • Interchange revenue increased by $0.5 million to a record $3.7 million, reflecting the benefit of recent growth in business banking customers and marketing targeted at increasing spend behavior by our customers. • Wealth management income increased to a record $2.0 million, reflecting the benefit of continued growth in assets under management, reaching $793 million at September 30, 2020, a 31% increase from the prior year. • Other income includes securities gains of $1.2 million in the second quarter of 2020, offset by nominal activity in the third quarter of 2020. 1Non-GAAP measure, see “Explanation of Certain Unaudited Non-GAAP Financial Measures" for more information and a reconciliation to GAAP 2Other Income includes marine finance fees, swap related income and other fees related to customer activity as well as securities THIRD QUARTER 2020 gains of $1.2 million in 2Q'20 and securities losses of $0.8 million in 3Q'19. 3Other Income on an adjusted basis includes marine finance fees, swap related income and other fees related to customer activity. 7
Continued Focus on Disciplined Expense Control Noninterest Expense ($ in thousands) Adjusted Noninterest Expense1 ($ in thousands) 2 2 Noninterest expense increased $9.3 million and adjusted noninterest expense1 increased $4.8 million sequentially. Results for the third quarter include $4.3 million of merger- related costs and $0.5 million in branch consolidation costs, both of which are excluded on an adjusted basis. Changes quarter-over-quarter on an adjusted basis include: • Salaries and benefits increased by $3.0 million, or 13%. In the second quarter of 2020, higher loan production driven by the PPP program resulted in higher deferrals of related salary expenses in that quarter, impacting the quarter-over-quarter comparison by $2.9 million. • Legal and professional decreased $0.3 million reflecting lower legal fees incurred on non-merger related activities. • Other expenses increased $1.4 million, or 27%, which reflects the impact of higher mortgage loan production-related expenses associated with higher production volumes, higher marketing costs, and higher executive recruiting fees in the quarter. • Provision for credit losses on unfunded commitments increased $0.6 million, primarily associated with loan commitments acquired in the Freedom Bank merger. 1Non-GAAP measure, see “Explanation of Certain Unaudited Non-GAAP Financial Measures" for more information and a reconciliation to GAAP 2Other Expense includes marketing expenses and other expenses associated with ongoing business operations.

Efficiency Ratio Trend GAAP - Efficiency Adjusted - Efficiency1 First Green Bank Palm Beach Freedom CommunityPBCB Bank and Bank and NorthNorthStar Star Bank Bank Acquisitions First Bank of the Palm Beaches Palm Beach Community and Palm Bank AcquisitionNorth Star • The efficiency ratio was 61.6% compared to 50.1% in the prior quarter and 48.6% in the third quarter of 2019. Merger-related costs of $4.3 million, branch consolidation costs of $0.5 million, and lower PPP related revenue were primary drivers of the increase in efficiency ratio. • The adjusted efficiency ratio1 was 54.8% compared to 49.6% in the prior quarter and 49.0% in the third quarter of 2019. The current quarter was impacted by the change in PPP fee accretion. 1Non-GAAP measure, see “Explanation of Certain Unaudited Non-GAAP Financial Measures" for more information and a reconciliation to GAAP THIRD QUARTER 2020 9
Disciplined Approach to Lending in an Uncertain Environment Total Loans Outstanding ($ in millions) • Loans outstanding totaled $5.9 billion, an increase of $872 million, or 17%, year-over-year. • New non-PPP loan originations of $338 million in the third quarter compared to $311 million in the prior quarter, with strong results in saleable residential mortgage offset by lower commercial production. • Excluding loans of $309 million acquired from Freedom Bank and PPP loans, loans outstanding decreased by $231 million quarter-over-quarter, affected by high levels of portfolio runoff, lesser pipeline-building activities earlier in the year during pandemic-related shutdowns, and lower demand for credit facilities from business customers. • Exiting the third quarter of 2020, pipelines were $256 million in commercial, $17 million in consumer, and $183 million in residential mortgages, compared to $117 million, $31 million and $108 million, respectively, in the prior quarter. • The yield on loans, excluding PPP and accretion on acquired loans, declined from 4.31% in the second quarter of 2020 to 4.22% in the third quarter, driven by early payoffs and the lower yield curve. THIRD QUARTER 2020 10
Strong Deposit Franchise Supported by Attractive Markets Deposits Outstanding ($ in millions) • Total deposits increased $248 million, or 4%, quarter- over-quarter and increased $1.2 billion, or 22%, compared to the third quarter of 2019. • Excluding deposits of $330 million acquired from Freedom Bank, deposits decreased $81.1 million, or 1%, compared to the prior quarter. Third quarter balances include a decrease of $47 million in brokered deposits. • Overall cost of deposits decreased to 24 basis points from 31 basis points in the prior quarter. • Transaction accounts increased 37% year-over-year, reflecting continued strong growth in core customer 55% balances, and represent 55% of overall deposit funding. • We estimate that 60% of funds from PPP originations remain in deposit accounts. THIRD QUARTER 2020 11
Cost of Deposits Deposit Mix and Cost of Deposits Trended Cost of Deposits 0.73% 0.61% 0.57% 0.31% 0.24% Cost of Deposits Cost of deposits declined seven basis points quarter over quarter, reflecting the significant value of the deposit franchise. We believe that Seacoast's continued focus on organic growth and relationship-based funding, in combination with its innovative analytics platform, supports a well-diversified low-cost deposit portfolio. THIRD QUARTER 2020 12
Investment Securities Performance and Composition Portfolio yield declined 56 basis points to 2.12% from 2.68% in the prior quarter. The decline is attributed to faster prepayments, rate resets and lower yielding portfolio additions in the third quarter. The net unrealized gain increased from $31.5 million to $33.6 million, largely due to Collateralized Loan Obligation (CLO) appreciation from June levels.
