SEACOAST REPORTS THIRD QUARTER 2022 RESULTS

Significant Expansion in Net Interest Margin and Net Interest Income Highlight Q3 Results

Well-Positioned Balance Sheet with Strong Capital and Liquidity

STUART, Fla., October 27, 2022 /GLOBE NEWSWIRE/ -- Seacoast Banking Corporation of Florida ("Seacoast" or the "Company") (NASDAQ: SBCF) today reported net income in the third quarter of 2022 of $29.2 million, or $0.47 per diluted share. Third quarter 2022 net income decreased 11% compared to the second quarter of 2022 due to higher provision for credit losses resulting from changes in economic forecast factors, and additional coverage for estimated economic impacts from Hurricane Ian. Third quarter 2022 net income increased 27% compared to the third quarter of 2021. Adjusted net income1 for the third quarter of 2022 was $32.8 million, or $0.53 per diluted share. Third quarter 2022 adjusted net income1 decreased 10% compared to the second quarter of 2022 due to a higher provision for credit losses. Third quarter 2022 adjusted net income1 increased 12% compared to the third quarter of 2021. Pre-tax pre-provision earnings1 were $43.1 million in the third quarter of 2022, an increase of 1% compared to the second quarter of 2022 and 23% compared to the third quarter of 2021. Adjusted pre-tax pre-provision earnings1 were $49.0 million in the third quarter of 2022, an increase of 6% compared to the second quarter of 2022 and 12% compared to the third quarter of 2021.

At September 30, 2022, the ratio of tangible common equity to tangible assets increased to 9.79%, and tangible book value per share was $15.98. A decline in the value of the available for sale securities portfolio, driven by rising interest rates during the first three quarters of 2022, negatively impacted the ratio of tangible common equity to tangible assets by 159 basis points and negatively impacted tangible book value per share by $2.93 compared to December 31, 2021.

For the third quarter of 2022, return on average tangible assets was 1.17%, return on average tangible shareholders' equity was 11.53%, and the efficiency ratio was 57.13%, compared to 1.29%, 13.01%, and 56.22%, respectively, in the prior quarter, and 1.00%, 9.56%, and 59.55%, respectively, in the prior year quarter. Adjusted return on average tangible assets1 in the third quarter of 2022 was 1.27%, adjusted return on average tangible shareholders' equity1 was 12.48%, and the adjusted efficiency ratio1 was 53.28%, compared to 1.38%, 13.97%, and 53.15%, respectively, in the prior quarter, and 1.23%, 11.72%, and 51.50%, respectively, in the prior year quarter.

Charles M. Shaffer, Seacoast's Chairman and CEO, said, "Seacoast’s team delivered another solid quarter, highlighted by a significant increase in the net interest margin and net interest income, disciplined growth in loan outstandings, and continued strong asset quality metrics. In addition, quarter over quarter, adjusted pre-tax pre-provision earnings of $49.0 million improved 6%, driven by a material increase in net interest income."

Shaffer added, "We continue to operate the company with a robust balance sheet, fortified by a tangible common equity ratio of 9.79%, which increased over the prior quarter despite rising interest rates that impacted accumulated comprehensive income. We saw continued improvements in already strong credit quality metrics, and the allowance for credit losses totals $95.3 million, with an additional $19.1 million in purchase discount on acquired loans. This provides meaningful loss absorption capacity which, when aggregated, represents 1.71% of loans outstanding. Seacoast’s balance sheet is supported by one of the best customer franchises in the industry, delivering low-cost funding and liquidity. We closed the quarter with a loan to deposit ratio of 76% which, looking forward, allows remix of the balance sheet to higher-yielding earning assets to support continued growth in net interest income."

Shaffer concluded, "I would like to thank all Seacoast associates for focusing on quickly recovering from Hurricane Ian and assisting our customers after the storm passed. All Seacoast branch offices were open within a few days, and the team rapidly pivoted and completed the Apollo and Drummond acquisitions. The team showed remarkable commitment and resilience in the face of a significant weather event, and I am very proud of all involved."

Acquisitions Update

Seacoast’s balanced growth strategy, combining organic growth with value-creating acquisitions, continues to benefit shareholders and expand the franchise across Florida.

On October 7, 2022, the Company completed the previously announced acquisition of Apollo Bancshares, Inc. (“Apollo”), which added approximately $718 million in loans and $857 million in deposits, and will provide expansion into Miami-Dade county, one of the fastest growing and most dynamic markets in the United States. System conversion activities were completed immediately after the closing of the transaction.

Also on October 7, 2022, the Company completed the previously announced acquisition of Drummond Banking Company (“Drummond”), providing Seacoast with an entry point into Gainesville, Ocala, and surrounding markets adding low-cost core deposits and diversified business lines. At the closing date, Drummond had approximately $590 million in loans and $882 million in deposits, providing a strong core deposit base, which highlights depository relationships that will provide a stable funding source for future loan growth and higher margins in a rising rate environment. Full integration and system conversion activities are expected to be completed in the first quarter of 2023.

On August 8, 2022, the Company announced its proposed acquisition of Professional Holding Corp. (“Professional”) (NASDAQ: PFHD), the sixth largest bank headquartered in South Florida. The transaction, which is expected to close in the first quarter of 2023, will increase market share in Miami-Dade, Broward, and Palm Beach counties. Full integration and system conversion activities are expected to be completed late in the second quarter of 2023.

In the first quarter of 2022, Seacoast completed the acquisitions of Sabal Palm Bancorp, Inc. (“Sabal Palm”) in Sarasota and Business Bank of Florida Corp. (“BBFC”) in Brevard County, which collectively added a combined $368 million in loans and $562 million in deposits. Integration activities, including system conversion, were completed in the first quarter of 2022 for BBFC and in the second quarter of 2022 for Sabal Palm.

Update on Hurricane Ian

In late September, communities across our corporate footprint were impacted by Hurricane Ian. We maintained uninterrupted digital and telephone access for our customers and, having experienced minimal impacts to our branch properties, we fully reopened to serve our communities shortly after the storm had passed. Recovery efforts in many areas continue and the full impacts on people and businesses in the most hard-hit regions are not fully known. In light of these uncertainties, the Company added $2.1 million to the provision for credit losses.

•Other income increased by $0.2 million in the third quarter of 2022, compared to the prior quarter, with increases in SBIC investment income offset by lower loan-swap related income.

•The Company recognized $0.4 million in securities losses in the third quarter of 2022, compared to $0.3 million in the second quarter of 2022 and nominal losses in the third quarter of 2021. Losses in each period represent mark to market adjustment on the Company’s CRA-qualified mutual fund.

•The provision for credit losses was $4.7 million in the third quarter of 2022, compared to $0.8 million in the prior quarter. The increase reflects loan growth, along with changes in economic forecast factors, and losses that may result from the impact of Hurricane Ian on our borrowers.

sbcflogoa.gif

•Salaries and wages increased $0.4 million to $28.4 million in the third quarter of 2022. During the third quarter the Company had the opportunity to invest in a team of well-seasoned C&I focused commercial bankers, treasury officers, and credit officers in North Florida, complementing our acquisition of Drummond and further expanding our reach in Ocala and Gainesville. Additionally, we expanded our commercial banking team in West and Central Florida, adding a significant number of bankers in these markets. Lastly, we hired numerous support and treasury roles supporting the Company’s successful strategy of banking middle market operating companies.

•Outsourced data processing costs decreased by $0.7 million in the third quarter of 2022, primarily attributed to merger related conversion costs incurred in the second quarter of 2022.

•Occupancy costs increased quarter over quarter as a result of the Company acquiring two branch properties that it had previously leased. The resulting write-offs of lease assets of $0.9 million impacted occupancy expense during the quarter, with ongoing expected annual savings of $0.3 million in net occupancy expense on these branches.

•Legal and professional fees increased by $0.8 million to $3.8 million in the third quarter of 2022, reflecting higher merger-related expenses and professional fees on a project that was completed.

•The prior quarter included a $1.0 million gain on sale of an OREO property. No OREO sale activity occurred in the third quarter.

•Other expenses increased by $2.2 million, primarily reflecting higher merger-related expenses and higher recruiting costs.

•A $1.0 million provision for credit losses on unfunded commitments reflects modeled results of changes in economic factors.

The increase in the ratio was primarily driven by a decline in total assets from the prior quarter.

•The efficiency ratio was 57.13% in the third quarter of 2022, compared to 56.22% in the second quarter of 2022 and 59.55% in the prior year quarter.

•Nonperforming loans decreased by $5.0 million to $21.5 million at September 30, 2022. Nonperforming loans to total loans outstanding were 0.32% at September 30, 2022, 0.40% at June 30, 2022, and 0.55% at September 30, 2021.

•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. Seacoast's average commercial loan size is $589 thousand, 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 30% and 191% of total bank-level risk-based capital, respectively, compared to 29% and 192% respectively, at June 30, 2022.

•Cash and cash equivalents at September 30, 2022 totaled $218.6 million, with decreases from the prior quarter resulting from loan growth, more modest deployment of liquidity in investments in the securities portfolio, and deposit outflows.

•Tangible common equity to tangible assets was 9.79% at September 30, 2022, compared to 9.74% at June 30, 2022, and 10.62% at September 30, 2021. Declines in the value of available for sale securities due to rising interest rates in 2022 negatively impacted equity year to date by $180.2 million.

•At September 30, 2022, the Company had available unsecured lines of credit of $165.0 million and lines of credit under lendable collateral value of $2.1 billion. Additionally, $2.1 billion of debt securities and $959.3 million of residential and commercial real estate loans are available as collateral for potential borrowings.

Third Quarter 2022 Strategic Highlights

Capitalizing on Seacoast’s Commitment to Digital Transformation

•During the third quarter, Seacoast launched several new digital banking features by building an even more competitive digital experience while positioning the bank to scale across the state. The addition of an online account opening functionality streamlines account opening for customers and enhanced fraud protection tools for both businesses and consumers provides additional safeguards.

•Seacoast’s online banking features are now available in both English and Spanish, supporting customer preferences and enhancing our ability to bring relationship-based banking to markets across the state.

Driving Sustainable Growth and Expanding our Footprint

•As the Company continues its focus on building the leading commercial bank in Florida, Chris Rolle and Brannon Fitch, previously Regional Presidents in West and North Florida, respectively, have taken on new roles as South Group President and North Group President, responsible for leading the commercial banking teams in their respective markets.

•During the quarter, the Company recruited a well-seasoned and successful C&I focused commercial banking team in North Florida, complementing the Drummond acquisition, and expanding its reach into Ocala and Gainesville. The Company also expanded its commercial banking team in West and Central Florida. Additionally, well-seasoned successful treasury talent was added to the franchise in multiple markets, supporting the Company’s successful strategy of banking middle market operating companies.

•The Company completed the acquisition of Apollo Bancshares, Inc. on October 7, 2022, adding meaningful scale in Miami-Dade county and a growth-oriented team with deep local relationships. The technology conversion went extremely well, and the Miami-Dade county team is now fully focused on growing the franchise.

•Also on October 7, 2022, the Company completed the acquisition of Drummond Bancshares, Inc. Drummond is a 32 year-old institution with a seasoned, consistently profitable franchise. Its low-cost core deposits are driven by deep customer loyalty, and the acquisition adds presence in the rapidly growing North Florida market. As of September 30, 2022, Drummond’s demand deposits represented 78% of its total deposits.

•The upcoming acquisition of Professional Holding Corp. expands the Company’s presence in the tri-county South Florida area, with a relationship-driven team focused on local businesses. The acquisition will further enhance Seacoast’s branch network and add scarcity value in a robust banking market.

Scaling and Evolving Our Culture

•Seacoast has been recognized by the Human Rights Foundation for the third consecutive year, earning a perfect score for Workplace Equality in the 2022 Corporate Equality index.

•For the second year in a row, Seacoast is thrilled to be named one of the Orlando Business Journal's 2022 Best Places to Work, which highlights our commitment to employees’ well-being, as well as our numerous diversity and inclusion initiatives.

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.

EARNINGS PRESENTATION THIRD QUARTER 2022 2022


2THIRD QUARTER 2022 EARNINGS PRESENTATION This presentation contains “forward-looking statements” within the meaning, and protections, of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, including, without limitation, statements about future financial and operating results, cost savings, enhanced revenues, economic and seasonal conditions in the Company’s markets, and improvements to reported earnings that may be realized from cost controls, tax law changes, new initiatives and for integration of banks that the Company has acquired, or expects to acquire, including Apollo Bancshares, Inc., Drummond Banking Company, and Professional Holding Corp., as well as statements with respect to Seacoast's objectives, strategic plans, expectations and intentions and other statements that are not historical facts, any of which may be impacted by the COVID-19 pandemic and any variants thereof and related effects on the U.S. economy. Actual results may differ from those set forth in the forward-looking statements. 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, which may be beyond the Company’s control, and which may cause the actual results, performance or achievements of Seacoast to be materially different from future results, performance or achievements expressed or implied by such forward-looking statements. You should not expect the Company to update any 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 impact 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, as well as legislative, tax and regulatory changes, including those that impact the money supply and inflation; changes in accounting policies, rules and practices, including the impact of the adoption of the current expected credit losses (“CECL”) methodology; 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 (including as a result of economic factors); 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; our ability to comply with any regulatory requirements; the effects of problems encountered by other financial institutions that adversely affect Seacoast or the banking industry; the Company’s concentration in commercial real estate loans and in real estate collateral in 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; 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, successfully acquire and integrate desirable financial institutions and realize expected revenues and revenue synergies; 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 Company’s business; dependence on key suppliers or vendors to obtain equipment or services for the business on acceptable terms, including the impact of supply chain disruptions; reduction in or the termination of Seacoast’s ability to use the online- or mobile-based platform that is critical to the Company’s business growth strategy; the effects of war or other conflicts including the impacts related to or resulting from Russia’s military action in Ukraine, 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 Paycheck Protection Program (“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 the Company’s 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. The risks relating to the mergers with Apollo Bancshares, Inc., Drummond Banking Company, and Professional Holding Corp. include, without limitation: the diversion of management's time on issues related to the mergers; unexpected transaction costs, including the costs of integrating operations; the risks that the businesses will not be integrated successfully or that such integration may be more difficult, time-consuming or costly than expected; the potential failure to fully or timely realize expected revenues and revenue synergies, including as the result of revenues following the mergers being lower than expected; the risk of deposit and customer attrition; any changes in deposit mix; unexpected operating and other costs, which may differ or change from expectations; the risks of customer and employee loss and business disruptions, including, without limitation, as the result of difficulties in maintaining relationships with employees; increased competitive pressures and solicitations of customers by competitors; as well as the difficulties and risks inherent with entering new markets.

24THIRD QUARTER 2022 EARNINGS PRESENTATION 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.
