During 2022, the wealth management division added a record breaking $425 million in assets under management.

•The provision for credit losses was $14.1 million in the fourth quarter of 2022, compared to $4.7 million in the prior quarter. A $15.0 million provision recorded in the Apollo and Drummond acquisitions was partially offset by the release of $2.1 million added in the third quarter of 2022 for potential losses related to hurricane Ian that did not materialize.

We expect the full benefit of cost synergies to materialize beginning in the second quarter of 2023.

•Employee benefits increased $1.2 million to $5.3 million in the fourth quarter of 2022, reflecting higher payroll taxes and healthcare-related costs attributed to higher headcount.

The increase in the ratio was primarily driven by higher expenses during the quarter resulting from expansion of the franchise.

These forward-looking statements may not be realized due to a variety of factors, including, without limitation: the impact of current and future economic and market conditions generally (including seasonality) and in the financial services industry, nationally and within Seacoast’s primary market areas, including the effects of inflationary pressures, elevated interest rates, slowdowns in economic growth, and the potential for high unemployment rates, as well as the financial stress on borrowers and changes to customer and client behavior (including the velocity of loan repayment) and credit risk as a result of the foregoing; 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; the risks of changes in interest rates on the level and composition of deposits (as well as the cost of, and competition for, 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; 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; changes in accounting policies, rules and practices, including the impact of the adoption of the current expected credit losses (“CECL”) methodology; uncertainty related to the impact of LIBOR calculations on securities, loans and debt; changes in retail distribution strategies, customer preferences and behavior generally and 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; the Company’s concentration in commercial real estate loans and in real estate collateral in Florida; 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; 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, as well as the effect of a fall in stock market prices on our fee income from our brokerage and wealth management businesses; 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 merger with Professional Holding Corp. include, without limitation: the diversion of management's time on issues related to the merger; 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; regulatory enforcement and litigation risk; 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.

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.
