SEACOAST REPORTS FIRST QUARTER 2022 RESULTS

Disciplined Loan Growth, Strong Deposit Growth, and Rising Net Interest Margin Highlight Q1 Results

Well-Positioned Balance Sheet with Strong Capital and Liquidity

STUART, Fla., April 28, 2022 /GLOBE NEWSWIRE/ -- Seacoast Banking Corporation of Florida ("Seacoast" or the "Company") (NASDAQ: SBCF) today reported net income in the first quarter of 2022 of $20.6 million, or $0.33 per diluted share, which includes merger-related costs and a $5.1 million increase in the provision for credit losses associated with acquisition activity during the quarter. First quarter 2022 results represent a decrease of 43% compared to the fourth quarter of 2021, and a decrease of 39% compared to the first quarter of 2021. Adjusted net income1 for the first quarter of 2022 was $27.1 million, or $0.44 per diluted share, which includes the $5.1 million increase in the provision for credit losses associated with acquisition activity. First quarter 2022 adjusted results represent a decrease of 27% compared to the fourth quarter of 2021, and a decrease of 24% compared to the first quarter of 2021. At March 31, 2022, the ratio of tangible common equity to tangible assets was 9.89%, and tangible book value per share was $17.12. A decline in the value of the available for sale securities portfolio driven by rising interest rates during the period impacted the ratio of tangible common equity to tangible assets by 56 basis points and impacted tangible book value per share by $1.07.

For the first quarter of 2022, return on average tangible assets was 0.85%, return on average tangible shareholders' equity was 8.02%, and the efficiency ratio was 62.33%, compared to 1.51%, 14.29%, and 53.70%, respectively, in the prior quarter, and 1.70%, 15.62%, and 53.21%, respectively, in the prior year quarter. Adjusted return on average tangible assets1 in the first quarter of 2022 was 1.06%, adjusted return on average tangible shareholders' equity1 was 10.01%, and the adjusted efficiency ratio1 was 54.86%, compared to 1.49%, 14.11%, and 53.43%, respectively, in the prior quarter, and 1.75%, 16.01%, and 51.99%, respectively, in the prior year quarter.

Charles M. Shaffer, Seacoast's Chairman and CEO, said, “Seacoast’s investments in high-performing commercial banking talent across Florida drove disciplined organic loan growth this quarter and a material increase in the late-stage pipeline entering the second quarter. With broad expectations for rising rates, we believe that Seacoast’s asset-sensitive balance sheet and ample liquidity position us well for growth and the continued expansion of net interest margin, which increased nine basis points during the first quarter of 2022, and rose 14 basis points excluding the effects of PPP and accretion on acquired loans.”

“In the first quarter of 2022, we established a new market presence in Naples, Sarasota, and Jacksonville, and announced the proposed acquisition of Apollo Bancshares, Inc., bringing us five locations in Miami-Dade County. We believe that this expansion into some of the best banking markets in the United States will lead to strong franchise value creation in the coming years,” Shaffer added.

Acquisitions Update

On January 3, 2022, the Company completed the acquisitions of Sabal Palm Bancorp, Inc. (“Sabal Palm”) in Sarasota, and Business Bank of Florida Corp. (“BBFC”) in Brevard County, which added a combined $367.9 million in loans, $562.3 million in deposits, and a $5.1 million provision for credit losses at acquisition. Consolidation activities for BBFC, including system conversion, are substantially complete. System conversion for Sabal Palm is planned early in the second quarter of 2022.

On March 29, 2022, the Company announced its proposed acquisition of Apollo Bancshares, Inc. (“Apollo”). The transaction, which is expected to close early in the fourth quarter of 2022, will expand the Company’s presence in Miami-Dade County, which is part of the Miami-Fort Lauderdale-Pompano Beach MSA, Florida’s largest MSA and the 8th largest in the nation. Apollo operates five branches across Miami-Dade County with deposits of approximately $947 million and loans of $705 million as of March 31, 2022.

Financial Results

Income Statement

•Net income was $20.6 million, or $0.33 per diluted share for the first quarter of 2022, which includes $6.7 million in merger-related costs associated with acquisition activity during the quarter, and a $5.1 million increase in the provision for credit losses associated with onboarding Sabal Palm and BBFC. This compares to net income of $36.3 million, or $0.62, for the prior quarter, and $33.7 million, or $0.60, for the prior year quarter. Adjusted net income1 for the first quarter of 2022 was $27.1 million, or $0.44 per diluted share, which includes the $5.1 million increase in the provision for credit losses associated with onboarding Sabal Palm and BBFC. This compares to $36.9 million, or $0.62, for the prior quarter, and $35.5 million, or $0.63, for the prior year quarter. In the first quarter of 2022, loan growth including bank acquisitions resulted in a provision for credit losses of $6.6 million, compared to a reversal of provision of $3.9 million in the fourth quarter of 2021 and a reversal of provision of $5.7 million in the first quarter of 2021. Excluded from adjusted net income are $6.7 million in merger-related expenses in the first quarter of 2022, compared to $0.5 million in the fourth quarter of 2021 and $0.6 million in the first quarter of 2021.

•Net revenues were $91.9 million in the first quarter of 2022, an increase of $0.9 million, or 1%, compared to the prior quarter, and an increase of $7.6 million, or 9%, compared to the prior year quarter. Adjusted revenues1 were $92.3 million in the first quarter of 2022, an increase of $1.7 million, or 2%, compared to the prior quarter, and an increase of $8.0 million, or 9%, compared to the prior year quarter.

•Net interest income totaled $76.5 million in the first quarter of 2022, an increase of $4.2 million, or 6%, from the fourth quarter of 2021, and an increase of $9.9 million, or 15%, compared to the first quarter of 2021. Increases relating to higher balances and higher yields on securities and loans were partially offset by declines in PPP interest and fees, while interest expense remained flat.

•Net interest margin increased to 3.25% in the first quarter of 2022 compared to 3.16% in the fourth quarter of 2021, the result of higher yields on non-PPP loans and on securities. Excluding the effect of PPP and accretion on acquired loans, net interest margin increased 14 basis points to 3.05% in the first quarter of 2022 from 2.91% in the fourth quarter of 2021. Securities yields increased 11 basis points to 1.68%, reflecting the impact of the addition of higher yielding securities during the quarter. Non-PPP loan yields increased six basis points to 4.24%. The effect on net interest margin of accretion of purchase discounts on acquired loans in the first quarter of 2022 was an increase of 15 basis points, consistent with the prior quarter. The effect on net interest margin of interest and fees on PPP loans was an increase of five basis points in the first quarter of 2022 compared to an increase of ten basis points in the prior quarter. The cost of deposits remained at only six basis points for the first quarter of 2022. The margin benefited from the Company’s asset sensitivity, combined with disciplined growth across the balance sheet.

•Noninterest income totaled $15.4 million in the first quarter of 2022, a decrease of $3.3 million, or 18%, compared to the prior quarter, and a decrease of $2.3 million, or 13%, compared to the prior year quarter. The decrease from the prior quarter primarily reflects a decrease of $3.4 million in income on SBIC investments, which is expected to vary amongst periods. In addition, the sale of a website domain name resulted in a gain of $0.8 million, benefiting results in the fourth quarter of 2021. Results for the first quarter of 2022 included the following:

•Wealth management income was $2.7 million in the first quarter of 2022, an increase of $0.3 million compared to the prior quarter, reflecting continued success in winning new relationships.

•Mortgage banking fees were $1.7 million, compared to $2.0 million in the prior quarter, the result of lower saleable production due to low housing inventory and slowing refinance demand.

•Other income decreased by $3.4 million in the first quarter of 2022, reflecting lower income on SBIC investments and a gain in the fourth quarter of 2021 on the sale of a website domain name, partially offset by higher loan-swap related income.

•The Company recognized $0.5 million in securities losses in the first quarter of 2022 compared to $0.4 million in the fourth quarter of 2021.

•The efficiency ratio was 62.33% in the first quarter of 2022, compared to 53.70% in the prior quarter and 53.21% in the prior year quarter. The increase in the first quarter of 2022 primarily reflects the impact of merger-related expenses. The adjusted efficiency ratio1 was 54.86% in the first quarter of 2022, compared to 53.43% in the prior quarter and 51.99% in the prior year quarter.

Balance Sheet

•At March 31, 2022, the Company had total assets of $10.9 billion and total shareholders' equity of $1.4 billion. Book value per share was $22.15 on March 31, 2022, compared to $22.40 on December 31, 2021, and $20.89 on March 31, 2021.

A decline in the value of the available for sale securities portfolio driven by rising interest rates during the period impacted tangible book value per share by $1.07.

•Debt securities totaled $2.5 billion on March 31, 2022, an increase of $170.7 million, or 7%, compared to December 31, 2021.

The Company continues to take a prudent and disciplined approach to reinvesting liquidity.

The company continues to exercise a disciplined approach to loan growth, carefully underwriting loans to strict underwriting guidelines.

•Commercial originations were $373.0 million during the first quarter of 2022, compared to $408.9 million in the fourth quarter of 2021, and $204.3 million in the first quarter of 2021. Despite a seasonally slower quarter, commercial originations remained strong and pipelines continued to build during the quarter.

Limited housing inventory and slowing refinance activity contributed to lower production.

The increase in pipeline reflects the addition of well-established commercial bankers and expansion into new markets across the state. The addition of experienced commercial bankers over the last 12 months is generating disciplined growth in full relationships, including credit facilities, deposit relationships, and wealth opportunities.

•Consumer pipelines were $61.6 million as of March 31, 2022, compared to $29.7 million at December 31, 2021, and $28.1 million at March 31, 2021. The increase is primarily the result of consumer lending teams that joined in late 2021.

•The acquisitions of BBFC and Sabal Palm resulted in additions of $562.3 million in total deposits during the first quarter of 2022. Removing the impact of acquisitions and wholesale activity, deposits increased 25% on an annualized basis.

•Transaction account balances, excluding those acquired from BBFC and Sabal Palm, increased $498 million, or 10%, quarter-over-quarter, and at March 31, 2022, total transaction account balances represent 62% of overall deposit funding.

•The Company manages excess liquidity on the balance sheet through participation in programs with third-party deposit networks. Through these programs, the Company can offer its customers access to FDIC insurance on large balances with attractive terms, and the Company can retain or sell, on an overnight basis, the underlying deposits.

First Quarter 2022 Strategic Highlights

Capitalizing on Seacoast’s Commitment to Digital Transformation

•Seacoast successfully launched an upgraded online and mobile banking platform in February 2022 that unifies the user experience, offering new functionality and consistent features across all devices. New features include Zelle®, account aggregation, reporting tools and more. The enhanced digital banking experience for both consumers and businesses complements exceptional branch, ATM, and telephone banking services to deliver a competitive value proposition.

Driving Sustainable Growth and Expanding our Footprint

•Seacoast’s balanced growth strategy includes organic growth initiatives across the state. Seacoast expanded its footprint in Naples/Southwest Florida and Jacksonville/Northeast Florida with key additions to its commercial banking leadership and teams. In the first quarter of 2022, Seacoast added 14 experienced bankers in the state’s most dynamic and fastest growing markets and expects to continue to invest in well-established seasoned bankers over the remainder of the year.

•With a focus on leading sustainable growth while maintaining Seacoast’s commitment to disciplined underwriting standards, James Stallings joined Seacoast as executive vice president and chief credit officer. Stallings’ career includes over two decades with BB&T where, as a senior credit executive, he oversaw a large team of credit officers and a $60 billion portfolio. In addition, he has held a diverse set of roles, including overseeing credit for the commercial community bank, corporate C&I, and specialty finance.

Scaling and Evolving Our Culture

•A strong history of value-creating acquisitions continues to benefit shareholders and provide new opportunities for associates. The Seacoast team grew during the first quarter of 2022 with the addition of experienced bankers and the merging of the teams from Sabal Palm Bank and Florida Business Bank. The combined scale and talent further supports our sustainable, profitable growth.

•Seacoast was recognized by the Human Rights Foundation for earning a perfect score of 100 for workplace equality on the 2022 Corporate Equality Index. This is the third consecutive year Seacoast has earned such recognition for its employment practices.

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.
