Acquisitions Update

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

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.

On October 7, 2022, the Company completed the acquisition of Apollo Bancshares, Inc. (“Apollo”), adding approximately $665 million in loans and $855 million in deposits, and taking Seacoast 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 acquisition of Drummond Banking Company (“Drummond”), providing Seacoast with an entry point into Gainesville, Ocala, and surrounding markets and adding low-cost core deposits and diversified business lines. At closing, Drummond had approximately $545 million in loans and $883 in deposits, providing a strong core deposit base and also highlighting the benefits of stable depository relationships we expect to be able to support 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 Seacoast’s market share in Miami-Dade, Broward, and Palm Beach counties.

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.

•Noninterest expense was $91.5 million in the fourth quarter of 2022, an increase of $30.2 million, or 49%, compared to the prior quarter, and an increase of $41.2 million, or 82%, compared to the prior year quarter.

•Occupancy, telephone and data lines, and furniture and equipment expenses collectively increased $1.1 million to $8.6 million in the fourth quarter of 2022, reflecting the expanded footprint from the addition of Apollo and Drummond locations.

•Legal and professional fees increased by $5.4 million to $9.2 million in the fourth quarter of 2022, including a $4.7 million increase in merger-related expenses during the quarter.

•Other expenses decreased by $1.4 million, driven by lower recruiting costs in the quarter.

•Amortization of intangibles increased $3.3 million with the addition of $61.7 million in intangible assets from the acquisitions of Drummond and Apollo. These assets will be amortized using an accelerated amortization method over approximately six years.

•Seacoast recorded $7.8 million of income tax expense in the fourth quarter of 2022, compared to $9.1 million in the third quarter of 2022 and $8.3 million in the fourth quarter of 2021.

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

•The efficiency ratio was 63.39% in the fourth quarter of 2022, compared to 57.13% in the third quarter of 2022 and 53.70% in the prior year quarter.

2021. As higher interest rates begin to slow loan demand, we remain focused on generating disciplined growth in full relationships, including credit facilities, deposit relationships, and wealth opportunities.

•Commercial pipelines were $395.7 million as of December 31, 2022, a decrease of 25% from $530.4 million at September 30, 2022, and a decrease of 1% from $397.8 million at December 31, 2021.

•Consumer pipelines were $36.6 million as of December 31, 2022, a decrease of 16% from $43.7 million at September 30, 2022, and an increase of 23% from $29.7 million at December 31, 2021.

•Residential saleable pipelines were $4.2 million as of December 31, 2022, compared to $6.6 million at September 30, 2022, and $30.1 million at December 31, 2021. Retained residential pipelines were $17.1 million as of December 31, 2022, compared to $60.7 million at September 30, 2022, and $25.6 million at December 31, 2021.

•Total deposits were $10.0 billion as of December 31, 2022, an increase of $1.2 billion, or 14%, compared to September 30, 2022, and an increase of $1.9 billion, or 24%, compared to December 31, 2021. The increase in the fourth quarter of 2022 includes $1.7 billion in deposits from acquired banks. The Company has continued to manage deposit pricing lower than competitors, and with an average loan-to-deposit ratio of 78% during the quarter, has maintained balance sheet flexibility supporting expansion of the net interest margin. The rising rate environment contributed to deposit outflows in the fourth quarter of 2022, which partially resulted in migration to wealth management and increases in assets under management.

•At December 31, 2022, the percentage of total transaction account balances to overall deposit funding was 64%, which continues to aid the Company’s ability to maintain a consistently low cost of deposits.

•The overall cost of deposits increased 12 basis points from the prior quarter to 21 basis points.

•Federal Home Loan Bank advances of $150.0 million with a weighted average rate of 3.42% were added late in the fourth quarter of 2022.

•Subordinated debt increased with the acquisition of $12.3 million in notes acquired in the Apollo transaction. The notes carry a fixed interest rate of 5.50% until 2025, convert to a floating rate until maturity in 2030, and are callable at the Company’s discretion.

Asset Quality

•Credit metrics remain strong with charge-offs, non-accruals, and criticized assets at historically low levels. The Company remains diligent in its monitoring of these metrics, as well as changes in the broader economic environment.

•Nonperforming loans increased by $7.4 million to $28.8 million at December 31, 2022. Nonperforming loans to total loans outstanding were 0.35% at December 31, 2022, 0.32% at September 30, 2022, and 0.52% at December 31, 2021.

•Nonperforming assets to total assets increased to 0.26% at December 31, 2022, compared to 0.23% at September 30, 2022, and 0.46% at December 31, 2021.

•Theratio of allowance for credit losses to total loans was 1.40% at December 31, 2022, 1.42% at September 30, 2022, and 1.41% at December 31, 2021. The decline in the fourth quarter of 2022 represents the release of $2.1 million added in the third quarter of 2022 for potential losses related to Hurricane Ian that did not materialize.

•Net charge-offs of $0.8 million for the fourth quarter of 2022 compared to $0.1 million in the third quarter of 2022 and $0.6 million in the fourth quarter of 2021. Net charge-offs for the four most recent quarters averaged 0.01%.

•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 $621 thousand, reflecting an ability to maintain granularity within the overall loan portfolio.

1Non-GAAP measure, see “Explanation of Certain Unaudited Non-GAAP Financial Measures" for more information and for a reconciliation to GAAP.    

•Construction and land development and commercial real estate loans remain well below regulatory guidance at 45% and 228% of total bank-level risk-based capital, respectively, compared to 30% and 191% respectively, at September 30, 2022. On a consolidated basis, construction and land development and commercial real estate loans represent 41% and 210%, respectively, of total consolidated risk-based capital.

Capital and Liquidity

•The Company continues to operate with a fortress balance sheet, with a tier 1 capital ratio at December 31, 2022, of 15.1% compared to 16.5% at September 30, 2022, and 17.4% at December 31, 2021. The total capital ratio was 16.1% and the tier 1 leverage ratio was 11.5% at December 31, 2022.

•Cash and cash equivalents at December 31, 2022 totaled $201.9 million, with decreases from the prior quarter resulting from loan growth and from lower deposit balances.

•Tangible common equity to tangible assets was 9.08% at December 31, 2022, compared to 9.79% at September 30, 2022, and 11.09% at December 31, 2021. Declines in the value of available for sale securities due to rising interest rates in 2022 negatively impacted equity year to date by $181.1 million.

•At December 31, 2022, the Company had available unsecured lines of credit of $175.0 million and lines of credit under lendable collateral value of $2.4 billion. Additionally, $2.0 billion of debt securities and $1.1 billion of residential and commercial real estate loans are available as collateral for potential borrowings.

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.

24FOURTH 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.
