SEACOAST REPORTS FIRST QUARTER 2021 RESULTS
Wealth Management Exceeds $1 Billion in Assets Under Management
Loan Pipelines Expand by 44% in Line with Strong Florida Economic Recovery
Initiates Quarterly Cash Dividend

STUART, Fla., April 22, 2021 /GLOBE NEWSWIRE/ -- Seacoast Banking Corporation of Florida ("Seacoast" or the "Company") (NASDAQ: SBCF) today reported net income in the first quarter of 2021 of $33.7 million, or $0.60 per diluted share, an increase of 15% compared to the fourth quarter of 2020. Adjusted net income1 for the first quarter of 2021 was $35.5 million, or $0.63 per diluted share, an increase of 16% compared to the fourth quarter of 2020. The ratio of tangible common equity to tangible assets was 10.71%, tangible book value per share increased to $16.62 and Tier 1 capital increased to 18.2%.
For the first quarter of 2021, return on average tangible assets was 1.70%, return on average tangible shareholders' equity was 15.62%, and the efficiency ratio was 53.21%, compared to 1.49%, 13.87%, and 48.23%, respectively, in the prior quarter. Adjusted return on average tangible assets1 in the first quarter of 2021 was 1.75%, adjusted return on average tangible shareholders' equity1 was 16.01%, and the adjusted efficiency ratio1 was 51.99%, compared to 1.50%, 14.00%, and 48.75%, respectively, in the prior quarter.
Charles M. Shaffer, Seacoast's President and CEO, said, “The Seacoast team delivered another record quarter, resulting in continued growth in tangible book value per share, ending the period at $16.62, up 15% over the prior year. Our wealth management team continues to implement a unique, high-quality approach to assisting high net worth families, foundations, and business owners in developing wealth and investment management strategies, resulting in strong growth year-over-year in assets under management. As the Florida population continues to swell and the economic recovery continues to take hold, we are capitalizing on this growth, as evidenced in our mortgage banking results, and in our loan pipelines, which increased 44% from year-end.
Mr. Shaffer added, “During the quarter, we announced the upcoming acquisition of Legacy Bank of Florida. This is an exceptional addition and further strengthens our presence in Florida’s largest MSA. The transaction, which is expected to close in the third quarter of 2021, will provide earnings per share accretion of 6% to 2022, and has nominal up-front dilution to tangible book value per share.”
On April 20, 2021, the Company’s Board of Directors approved a $0.13 cash dividend to shareholders of record on June 15, 2021, to be paid June 30, 2021.
Mr. Shaffer further commented, “I am pleased to announce the Board’s decision to authorize a quarterly dividend for our shareholders. The dividend demonstrates our continued confidence in the Company’s performance outlook. Asset quality, liquidity, and capital are all strong, and we continue to generate meaningful capital growth, bolstering our fortress balance sheet. Our capital ratios are more substantial than most of our peers, which continues to provide strategic flexibility, and issuing a dividend is yet another way we can provide total shareholder return while maintaining our balanced growth strategy.”

SBCFLOGO3.GIF
Net interest income totaled $66.6 million in the first quarter of 2021, a decrease of $2.2 million, or 3%, from the prior quarter due to lower loan balances and lower yields, partially offset by higher income from Paycheck Protection Program (“PPP”) loans and lower cost of deposits. During the first quarter of 2021, net interest income included $6.9 million in interest and fees earned on PPP loans compared to $5.2 million in the fourth quarter of 2020. Remaining deferred PPP loan fees totaling $13.5 million will be recognized over the loans' remaining contractual maturity or sooner, as loans are forgiven.
Net interest margin was 3.51% in the first quarter of 2021, compared to 3.59% in the fourth quarter of 2020. The effect of accretion of purchase discounts on acquired loans was an increase of 15 basis points in the first quarter of 2021, compared to an increase of 23 basis points in the fourth quarter of 2020. The effect of interest and fees on PPP loans was an increase of 11 basis points in the first quarter of 2021, and a decrease of one basis point in the fourth quarter of 2020. Excluding both these items, net interest margin declined 12 basis points to 3.25%, largely the result of significant growth in cash balances held on the balance sheet. The Company expects to deploy this cash in a disciplined and prudent manner, carefully navigating an economic outlook that includes expected increases in interest rates. The yield on loans, excluding PPP and accretion of purchase discount, decreased 8 basis points due to the impact of the overall lower rate environment. The yield on securities declined 8 basis points, resulting from elevated prepayments and lower yields on new purchases. The cost of deposits decreased six basis points, from 19 basis points in the fourth quarter of 2020 to 13 basis points in the first quarter of 2021, reflecting our continued repricing down of interest-bearing deposits and time deposits.
Noninterest income totaled $17.7 million in the first quarter of 2021, an increase of $2.7 million, or 18%, compared to the prior quarter. Results for the first quarter of 2021 included the following:
Mortgage banking fees were $4.2 million, compared to $3.6 million in the prior quarter, as rates remain low and an influx of new residents and businesses into Florida drive demand for mortgage originations.
Interchange revenue was a record $3.8 million, compared to $3.6 million in the prior quarter, with a higher volume of transactions and higher per-card spending contributing to the increase.
Wealth management income was a record $2.3 million in the current quarter, compared to $1.9 million in the fourth quarter of 2020. During the first quarter of 2021, assets under management increased $156 million to surpass $1.0 billion. This milestone was achieved as the result of the team’s success in delivering valuable services and advice to new clients, and collaborating with retail and commercial bankers across the franchise to build and develop existing relationships.
Included in other income in the first quarter of 2021 is $1.7 million in income associated with the resolution of contingencies on two loans acquired in 2017. Similar activity is not expected in subsequent periods.
The provision for credit losses was a net benefit of $5.7 million in the first quarter of 2021, compared to a $1.9 million expense in the prior quarter. The ratio of allowance for credit losses to total loans declined to 1.53% at March 31, 2021, compared to 1.62% at December 31, 2020. Excluding PPP loans, the ratio declined to 1.71% at March 31, 2021, compared to 1.79% at December 31, 2020. The decline in coverage reflects improvement in the economic outlook from the prior quarter.
Noninterest expense was $46.1 million in the first quarter of 2021, an increase of $2.4 million, or 6%, compared to the prior quarter. Changes from the fourth quarter of 2020 consisted of the following:
Employee benefits increased $1.1 million, or 27%, reflecting higher seasonal payroll taxes and 401(k) plan contributions typical of the first quarter.
Occupancy expenses include $0.3 million in charges associated with three branch consolidations completed during the first quarter of 2021.
Legal and professional fees increased by $2.1 million compared to the fourth quarter. The first quarter of 2021 includes $0.6 million in merger-related costs, while the fourth quarter benefited from the one-time recovery of certain legal expenses incurred during 2020.

SBCFLOGO3.GIF
Foreclosed property expense decreased in the first quarter of 2021 by $1.9 million, reflecting a gain on the sale of an OREO property of $0.2 million compared to write-downs totaling $1.6 million on two properties in the prior quarter.
Seacoast recorded $10.2 million of income tax expense in the first quarter of 2021, compared to $8.8 million in the prior quarter. Tax impacts related to stock-based compensation were nominal each period.
The ratio of net adjusted noninterest expense1 to average tangible assets was 2.16% in the first quarter of 2021, compared to 2.00% in the prior quarter and 2.46% in the first quarter of 2020.
The efficiency ratio was 53.2% compared to 48.2% in the prior quarter. The adjusted efficiency ratio1 was 52.0% compared to 48.8% in the prior quarter. The fourth quarter of 2020 benefited from a one-time recovery of legal expenses and a release of reserves for unfunded commitments, while the first quarter of 2021 included a seasonal increase in employee benefits.

Balance Sheet
At March 31, 2021, the Company had total assets of $8.8 billion and total shareholders' equity of $1.2 billion. Book value per share was $20.89, and tangible book value per share was $16.62, compared to $20.46 and $16.16, respectively, on December 31, 2020, and $18.82 and $14.42, on March 31, 2020. This reflects growth in tangible book value per share of 15% year-over-year. Increasing rates impacted accumulated other comprehensive income by $10.8 million, offsetting the quarter-over-quarter growth in tangible book value by $0.20 per share.
Debt securities totaled $1.6 billion on March 31, 2021, a decrease of $18.9 million compared to December 31, 2020. Purchases during the quarter were primarily in government-sponsored mortgage-backed securities with an average yield of 1.44%. On January 1, 2021, the Company transferred $211.6 million in debt securities from available-for-sale to held-to-maturity, as it has the intent and ability to hold these securities to maturity.
Loans totaled $5.7 billion on March 31, 2021, a decrease of $73.9 million, or 1%, compared to December 31, 2020. Given the significant economic performance in the State of Florida, low unemployment, and clear evidence of a V-shaped recovery, the Company returned to its pre-pandemic credit policy and conservative underwriting guidelines.
With the renewal of the Paycheck Protection Program (“PPP”), Seacoast originated over 2,400 loans for $232.5 million in the first quarter of 2021. Fees earned from the Small Business Administration (“SBA”) on the origination of these loans, net of related costs, totaled $9.4 million. When combined with fees remaining to be recognized on PPP loans originated in 2020, $13.5 million in deferred PPP loan fees will be recognized over the loans’ contractual maturity or sooner, as loans are forgiven. During the first quarter of 2021, $213.8 million in PPP loans funded in 2020 were forgiven by the SBA.
Loan originations were $668.4 million in the first quarter of 2021, compared to $541.0 million in the fourth quarter of 2020, an increase of 24%.
Commercial originations during the first quarter of 2021 were $204.3 million, compared to $277.4 million in the fourth quarter of 2020. The decrease reflects lower seasonal demand quarter-over-quarter, but an increase of 11% compared to the first quarter of 2020. We expect production to continue to increase throughout 2021.
Seacoast participated in the most recent round of PPP funding with $232.5 million in originations during the quarter.
Residential loans originated for sale in the secondary market were $138.3 million in the first quarter of 2021, compared to $161.6 million in the fourth quarter of 2020. The benefit of continued low rates and ongoing inflows of new residents and businesses into Florida drove continued demand for mortgage originations.
Closed residential loans retained in the portfolio totaled $46.6 million in the first quarter of 2021, compared to $54.5 million in the fourth quarter of 2020.

Consumer originations in the first quarter of 2021 were $46.7 million, compared to $47.5 million in the fourth quarter of 2020.
Pipelines (loans in underwriting and approval or approved and not yet closed) totaled $433.6 million on March 31, 2021, an increase of 44% from the fourth quarter of 2020.
Commercial pipelines were $240.9 million as of March 31, 2021, an increase of 44% from $166.7 million for the fourth quarter of 2020, reflecting increasing demand in line with Florida’s strong economic recovery.
Residential saleable pipelines were $92.1 million as of March 31, 2021, compared to $92.0 million as of the prior quarter end. Retained residential pipelines were $72.4 million as of March 31, 2021, compared to $25.1 million as of the prior quarter end. The increase in the retained residential pipeline reflects a selective Florida correspondent program we expanded during the quarter to generate both portfolio growth and cross-sell opportunities for depository and other products.
Consumer pipelines were $28.1 million as of March 31, 2021, compared to $18.2 million as of the prior quarter-end.
Total deposits were $7.4 billion as of March 31, 2021, an increase of $453.2 million, or 7%, compared to December 31, 2020.
The overall cost of deposits declined to 13 basis points in the first quarter of 2021 from 19 basis points in the prior quarter.
Total transaction account balances increased $477.3 million, or 12%, quarter-over-quarter, reflecting the impact of the new PPP originations, ongoing stimulus programs and tax refunds and growth in relationships. Transaction accounts represent 59% of overall deposit funding.
Interest-bearing deposits (interest-bearing demand, savings, and money market deposits) increased $275.9 million, or 7%, quarter-over-quarter to $4.1 billion, noninterest-bearing demand deposits increased $395.5 million, or 17%, to $2.7 billion, and CDs (excluding brokered) declined $77.8 million, or 13%, to $519.5 million.
As of March 31, 2021, deposits per banking center were $154 million, compared to $118 million on March 31, 2020.
Asset Quality
Nonperforming loans decreased by $0.8 million to $35.3 million at March 31, 2021. Nonperforming loans to total loans outstanding were 0.62% at March 31, 2021, 0.63% at December 31, 2020, and 0.48% at March 31, 2020.
Nonperforming assets to total assets were 0.58% at March 31, 2021, 0.59% at December 31, 2020, and 0.55% at March 31, 2020.
The ratio of allowance for credit losses to total loans was 1.53% at March 31, 2021, 1.62% at December 31, 2020, and 1.61% at March 31, 2020. Excluding PPP loans, the ratio of allowance for credit losses to total loans at March 31, 2021, was 1.71%, compared to 1.79% at December 31, 2020. The decline in coverage reflects an improvement in the economic outlook from the prior quarter, lower net charge-offs, and lower loans outstanding.
Net charge-offs were $0.4 million, or 0.03%, of average loans for the first quarter of 2021 compared to $3.1 million, or 0.21%, of average loans in the fourth quarter of 2020 and $1.0 million, or 0.07%, of average loans in the first quarter of 2020. Net charge-offs for the four most recent quarters averaged 0.12%.
Portfolio diversification, in terms of asset mix, industry, and loan type, has been a critical element of the Company's lending strategy. Exposure across industries and collateral types is broadly distributed. Excluding PPP loans, Seacoast's average commercial loan size is $408,000, reflecting an ability to maintain granularity within the overall loan portfolio.

Construction and land development and commercial real estate loans remain well below regulatory guidance at 23% and 168% of total bank-level risk based capital, respectively, compared to 26% and 169% respectively, in the fourth quarter of 2020. On a consolidated basis, construction and land development and commercial real estate loans represent 21% and 155%, respectively, of total consolidated risk-based capital.
Capital and Liquidity
The tier 1 capital ratio increased to 18.2% from 17.4% at December 31, 2020, and 15.5% March 31, 2020. The total capital ratio was 19.2% and the tier 1 leverage ratio was 12.1% at March 31, 2021.

Tangible common equity declined quarter-over-quarter as a result of a buildup of cash on the balance sheet. The Company will strategically deploy this cash in a disciplined and prudent manner, carefully navigating an outlook that includes expected increases in interest rates.
At March 31, 2021, the Company had available unsecured lines of credit of $135.0 million and lines of credit under lendable collateral value of $1.7 billion. $1.3 billion of debt securities and $703.8 million in residential and commercial real estate loans are available as collateral for potential borrowings.

First Quarter Strategic Highlights
Legacy Bank of Florida Acquisition
Seacoast’s balanced growth strategy, combining organic growth with value-creating acquisitions, continues to benefit shareholders and provide new opportunities for associates. In the first quarter of 2021, the Company announced the upcoming acquisition of Legacy Bank of Florida, which is expected to close in the third quarter of 2021. The acquisition will add experienced bankers in a growing market, further supporting sustainable, profitable growth, and will increase Seacoast’s deposits in Palm Beach and Broward counties by approximately 40%.
    
Capitalizing on Seacoast’s Early Commitment to Digital Transformation
As customer preferences change, Seacoast continues to evolve the branch footprint, redirecting capacity into attractive growth markets. In alignment with this strategy, three banking center locations were consolidated in the first quarter of 2021, representing an estimated annual savings of $0.9 million.
Seacoast and its customers are benefiting from our fully digital PPP origination platform and our automated PPP forgiveness solution, which streamline the processes for clients while integrating with Seacoast’s existing technology infrastructure. In the first quarter of 2021, with the re-opening of the PPP lending program, Seacoast originated $232.5 million in PPP loans. Also in the first quarter of 2021, Seacoast processed $213.8 million in loan forgiveness.
During the first quarter of 2021, Seacoast launched a large-scale initiative to upgrade all ATMs across the network through a third-party partnership, providing our customers with a best-in-class experience, while reducing the cost to operate the ATM network by $0.9 million annually.
Scaling and Evolving Our Culture
As Seacoast grows the organization, we continue to expand our leadership team with talented individuals holding diverse backgrounds. In the first quarter of 2021, Ron York joined Seacoast serving as EVP, Treasury Management Executive. Formerly with First Horizon Bank, Ron will look to evolve Seacoast’s Treasury Management products, services, and capabilities. Additionally, the Company hired Pam Notarantonio as the regional credit officer for the Central Florida market. Pam joins Seacoast after 32 years with Wells Fargo and brings extensive credit leadership experience to the role. This follows the hiring of Dan Hilken, also previously with Wells Fargo, in the fourth quarter as the regional market president for Central Florida.
Seacoast believes that diversity enhances our entire workforce, and we strive to make inclusion a hallmark of our culture. Our Associate Resource Group (“ARG”) programs are 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, LGBTQ+, Veterans, and Women Mean Business. Each is sponsored and supported by senior leaders across the enterprise.
Seacoast launched a new associate engagement & performance management platform in February of 2021. The tool provides an integrated platform supporting associate engagement and performance management routines, further supporting the bank’s high performance culture.

Explanation of Certain Unaudited Non-GAAP Financial Measures
This presentation contains financial information determined by methods other than Generally Accepted Accounting Principles (“GAAP”). 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.

25 FIRST QUARTER 2021 EARNINGS PRESENTATION Explanation of Certain Unaudited Non-GAAP Financial Measures This presentation 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, noninterest income, noninterest expense, tax adjustments 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.
