SEACOAST REPORTS SECOND QUARTER 2023 RESULTS

Well-Positioned Balance Sheet with Strong Capital and Liquidity

Distinctive Deposit Franchise with Granular, Longstanding Customer Base

STUART, Fla., July 27, 2023 /GLOBE NEWSWIRE/ -- Seacoast Banking Corporation of Florida ("Seacoast" or the "Company") (NASDAQ: SBCF) today reported net income in the second quarter of 2023 of $31.2 million, or $0.37 per diluted share, compared to $11.8 million, or $0.15 per diluted share in the first quarter of 2023 and $32.8 million, or $0.53 per diluted share in the second quarter of 2022. For the six months ended June 30, 2023, net income was $43.1 million, or $0.52 per diluted share, a decrease of 19% compared to the six months ended June 30, 2022.

Adjusted net income1 for the second quarter of 2023 was $49.2 million, or $0.58 per diluted share, compared to $29.2 million, or $0.36 per diluted share in the first quarter of 2023 and $36.3 million, or $0.59 per diluted share in the second quarter of 2022. Adjusted net income1 for the six months ended June 30, 2023 was $78.4 million, or $0.94 per diluted share, an increase of 24% compared to the six months ended June 30, 2022.

For the second quarter of 2023, return on average tangible assets was 1.06% and return on average tangible shareholders' equity was 12.08%, compared to 0.52% and 5.96%, respectively, in the prior quarter, and 1.29% and 13.01%, respectively, in the prior year quarter. Adjusted return on average tangible assets1 in the second quarter of 2023 was 1.41% and adjusted return on average tangible shareholders' equity1 was 16.08%, compared to 0.90% and 10.34%, respectively, in the prior quarter, and 1.38% and 13.97%, respectively, in the prior year quarter. For the six months ended June 30, 2023, return on average tangible assets was 0.80% and return on average tangible shareholders' equity was 9.14%, compared to 1.07% and 10.46%, respectively, for the six months ended June 30, 2022. For the six months ended June 30, 2023, adjusted return on average tangible assets1 was 1.16% and adjusted return on average tangible shareholders' equity1 was 13.32%, compared to 1.23% and 11.95%, respectively, for the six months ended June 30, 2022.

Charles M. Shaffer, Seacoast's Chairman and CEO said, "Seacoast delivered another quarter of robust financial performance, with strong adjusted earnings leading to an adjusted return on tangible common equity of 16.1%. Our capital and liquidity ratios were strong and our asset quality remains excellent. During the quarter, we successfully completed the Professional Bank conversion, wrapping up a significant period of M&A activity that has boosted Seacoast beyond the $10 billion asset threshold and definitively positioned the Company as Florida’s Bank.”

Shaffer added, “Seacoast is committed to our fortress balance sheet, with an allowance for loan losses of $159.7 million and an additional $201.8 million discount on acquired loans, providing significant loss absorption capacity. Our second quarter ratio of tangible common equity to tangible assets increased to 8.53% as we moved past the initially dilutive effect of recent acquisitions, reflecting commitment to driving shareholder value creation."

Shaffer concluded, "Our strategic focus for the balance of the year will be on relationship-driven customer acquisition and carefully managing our expense base while investing in tactics to drive low-cost deposit growth. We believe that this rigorous approach will support solid capital growth, produce a broadly diversified and stable funding base, and generate increased franchise value over the long run."

Acquisition Update

In June 2023, we successfully completed the integration of Professional Holding Corp. (“Professional”), including the consolidation of five branches in the South Florida market. Merger-related expense synergies are expected to be fully realized in the second half of 2023. Direct merger-related costs recorded during the second quarter of 2023 totaled $15.6 million. We expect merger-related costs to be insignificant in the third quarter of 2023.

Financial Results

Income Statement

•Net income was $31.2 million, or $0.37 per diluted share, for the second quarter of 2023 compared to net income of $11.8 million, or $0.15 per diluted share, for the prior quarter, and $32.8 million, or $0.53 per diluted share, for the prior year quarter. For the six months ended June 30, 2023, net income was $43.1 million, or $0.52 per diluted share, compared to $53.3 million, or $0.86 per diluted share, for the six months ended June 30, 2022. The results for the six months ended June 30, 2023 included the $26.6 million day-1 provision for credit losses on loans acquired in the Professional acquisition. Adjusted net income1 for the second quarter of 2023 was $49.2 million, or $0.58 per diluted share, compared to $29.2 million, or $0.36 per diluted share, for the prior quarter, and $36.3 million, or $0.59 per diluted share, for the prior year quarter. For the six months ended June 30, 2023, adjusted net income1 was $78.4 million, or $0.94 per diluted share, compared to $63.4 million, or $1.03 per diluted share, for the six months ended June 30, 2022.

•Net revenues were $148.5 million in the second quarter of 2023, a decrease of $5.1 million, or 3%, compared to the prior quarter, and an increase of $49.9 million, or 51%, compared to the prior year quarter. For the six months ended June 30, 2023, net revenues were $302.1 million, an increase of $111.6 million, or 59%, compared to the six months ended June 30, 2022. Adjusted revenues1 were $148.7 million in the second quarter of 2023, a decrease of $2.7 million, or 2%, compared to the prior quarter, and an increase of $49.8 million, or 50%, compared to the prior year quarter. For the six months ended June 30, 2023, adjusted revenues1 were $300.1 million, an increase of $108.8 million, or 57%, compared to the six months ended June 30, 2022.

•Pre-tax pre-provision earnings1 were $40.9 million in the second quarter of 2023, a decrease of 12% compared to the first quarter of 2023 and a decrease of 4% compared to the second quarter of 2022. Adjusted pre-tax pre-provision earnings1 were $64.9 million in the second quarter of 2023, a decrease of 9% compared to the first quarter of 2023 and an increase of 40% compared to the second quarter of 2022. Adjusted pre-tax pre-provision earnings1 for the six months ended June 30, 2023 were $135.9 million, an increase of $47.8 million, or 54%, when compared to the six months ended June 30, 2022.

•Net interest income totaled $127.0 million in the second quarter of 2023, a decrease of $4.2 million, or 3%, from the first quarter of 2023 and an increase of $45.3 million, or 56%, compared to the second quarter of 2022. When excluding accretion on acquired loans, net interest income declined $2.4 million. Accretion on acquired loans totaled $14.2 million in the second quarter of 2023, $15.9 million in the first quarter of 2023, and $2.7 million in the second quarter of 2022. For the six months ended June 30, 2023, net interest income was $258.1 million, an increase of $99.9 million, or 63%, compared to the six months ended June 30, 2022. Accretion on acquired loans totaled $30.1 million for the six months ended June 30, 2023, compared to $6.4 million for the six months ended June 30, 2022.

•Net interest margin decreased 45 basis points to 3.86% in the second quarter of 2023 compared to 4.31% in the first quarter of 2023. The decline in the net interest margin from the prior quarter was driven by the impact of rising rates on the competitive environment for deposits, the continued effect of an inverted yield curve, and lower accretion of purchase discounts on acquired loans. Loan yields increased three basis points to 5.89%. The effect on loan yields of accretion of purchase discounts on acquired loans in the second quarter of 2023 was an increase of 56 basis points, compared to an increase of 69 basis points in the first quarter of 2023. Securities yields increased 28 basis points to 3.13%, including approximately 12 basis points of benefit from interest rate swaps initiated in the second quarter. The cost of deposits increased 61 basis points, from 77 basis points in the prior quarter, to 1.38% for the second quarter of 2023.

•Noninterest income totaled $21.6 million in the second quarter of 2023, a decrease of $0.9 million, or 4%, compared to the prior quarter, and an increase of $4.6 million, or 27%, compared to the prior year quarter. For the six months ended June 30, 2023, noninterest income was $44.0 million, an increase of $11.7 million, or 36%, compared to the six months ended June 30, 2022. Results for the second quarter of 2023 included the following:

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

sbcflogoa.gif

•Service charges on deposits increased $0.3 million, or 7%, compared to the prior quarter and $1.2 million, or 34%, year over year, including the continued benefit of the expansion of treasury management services to commercial customers.

•Interchange income totaled $5.1 million in the second quarter, an increase of $0.4 million, or 8%, when compared to the prior quarter and $0.8 million, or 19%, compared to the prior year quarter. As a reminder, beginning in the third quarter of 2023, the Company’s interchange income will be reduced by the requirements of the Durbin amendment, which became effective for the Company on July 1, 2023.

•The wealth management division continues to demonstrate notable success in building relationships, and during the second quarter of 2023, income increased $0.3 million, or 8%, compared to the prior quarter and $0.5 million, or 20%, compared to the prior year quarter. Assets under management increased by $60 million in the second quarter of 2023, bringing total assets under management to $1.6 billion, up 36% from the prior year.

•Mortgage banking fees totaled $0.6 million in the second quarter, an increase of $0.2 million, or 35%, due to higher saleable production.

•Other income decreased by $1.8 million compared to the prior quarter, primarily the result of the recognition in the prior quarter of $2.1 million in bank owned life insurance (“BOLI”) death benefits.

•The provision for credit losses was a net benefit of $0.8 million in the second quarter of 2023, compared to a provision of $31.6 million in the first quarter of 2023 and a provision of $0.8 million in the second quarter of 2022. The provision for credit losses in the first quarter of 2023 included $26.6 million in day-1 provision recorded at the acquisition of Professional.

•Noninterest expense was $107.9 million in the second quarter of 2023, an increase of $0.4 million compared to the prior quarter, and an increase of $51.7 million, or 92%, compared to the prior year quarter. The second quarter of 2023 included $15.6 million of merger-related expenses, compared to $17.5 million in the prior quarter and $3.0 million in the prior year quarter. Noninterest expense was $215.3 million for the six months ended June 30, 2023, including $33.2 million in merger-related charges, compared to $115.1 million in the six months ended June 30, 2022, which included $9.7 million in merger-related charges. Changes compared to the first quarter of 2023 included:

•Salaries and wages decreased $2.5 million to $45.2 million in the second quarter of 2023. The second quarter of 2023 included $1.6 million in merger-related expenses, compared to $4.2 million in the first quarter of 2023.

•In the third quarter of 2023, we are continuing our focus on efficiency and streamlining operations, and in late July we executed a reduction in the Company’s workforce by approximately 5%. The Company will incur severance charges in a range of approximately $2.0 to $3.0 million. The resulting lower compensation expense in the third quarter of 2023 will largely be offset by investments in marketing expenses to drive low-cost deposit growth, and lower expense deferral associated with slowing loan originations. As a reminder, under the relevant accounting guidance, the Company defers the expenses associated with the origination of new loans, and recognizes this expense as a reduction to loan yield over the life of the loan. We expect the full benefit of the reduction in workforce to materialize in the fourth quarter of 2023.

•Employee benefits decreased $1.1 million to $7.5 million in the second quarter of 2023 as a result of higher seasonal payroll taxes impacting the first quarter of 2023.

•Outsourced data processing costs increased $5.7 million to $20.2 million in the second quarter of 2023. The second quarter of 2023 included $10.9 million in merger-related expenses, compared to $6.6 million in the first quarter of 2023. Termination penalties related to the Professional technology contracts were recorded in the second quarter in conjunction with the system conversion.

•Telephone and data lines increased $0.4 million to $1.5 million in the second quarter of 2023 reflecting the expansion of the branch footprint.

•Legal and professional fees decreased by $3.4 million to $4.1 million in the second quarter of 2023, and included $1.7 million in merger-related expenses during the second quarter of 2023 compared to $4.8 million of merger-related expenses in the first quarter of 2023.

•Amortization of intangibles increased by $0.9 million to $7.7 million resulting from the first full quarter of amortization of the core deposit intangible assets acquired from Professional. These assets are amortized using an accelerated amortization method.

•Other noninterest expenses increased $1.1 million to $8.3 million in the second quarter of 2023, primarily attributed to maintaining parallel activities and processes prior to the conversion of Professional in June 2023.

•Seacoast recorded $10.2 million of income tax expense in the second quarter of 2023, compared to $2.7 million in the first quarter of 2023, and $8.9 million in the second quarter of 2022, with an effective tax rate of 24.6%, 18.6%, and 21.3%, respectively. Impacts related to stock-based compensation were tax expense of $0.3 million in the second quarter of 2023, tax benefits of $0.2 million in the first quarter of 2023, and tax benefits of $0.4 million in the second quarter of 2022. The first quarter of 2023 included a discrete benefit of $0.6 million related to the BOLI distribution which, combined with lower overall pre-tax income, resulted in a lower effective tax rate in that period.

•The efficiency ratio was 67.34% in the second quarter of 2023, compared to 65.43% in the first quarter of 2023 and 56.22% in the prior year quarter. The adjusted efficiency ratio1 was 56.44% in the second quarter of 2023, compared to 53.10% in the first quarter of 2023 and 53.15% in the prior year quarter. The Company continues to remain keenly focused on disciplined expense control. The increase in the adjusted efficiency ratio primarily reflects the impact of higher deposit rates on net interest income in the period. The adjusted efficiency ratio1 for the six months ended June 30, 2023 was 54.76% compared to 53.97% for the six months ended June 30, 2022.

Balance Sheet

•At June 30, 2023, the Company had total assets of $15.0 billion and total shareholders' equity of $2.1 billion. Book value per share was $24.14 on June 30, 2023, compared to $24.24 on March 31, 2023, and $21.65 on June 30, 2022. Tangible book value per share totaled $14.24 on June 30, 2023 compared to $14.25 on March 31, 2023 and $16.66 on June 30, 2022. Removing the impact of the change in accumulated comprehensive income, tangible book value per share increased by $0.20.

•Debt securities totaled $2.6 billion on June 30, 2023, a decrease of $129.8 million, or 5%, compared to March 31, 2023. Debt securities include approximately $1.9 billion in securities held at fair value and classified as available for sale. The unrealized loss on these securities is fully reflected in the value presented on the balance sheet. The portfolio also includes $707.8 million in securities classified as held to maturity with a fair value of $577.6 million. Held-to-maturity securities consist solely of mortgage-backed securities and collateralized mortgage obligations guaranteed by U.S. government agencies, each of which is expected to recover any price depreciation over its holding period as the debt securities move to maturity. The Company has significant liquidity and available borrowing capacity and has the intent and ability to hold these investments to maturity.

•Loans decreased $16.5 million when compared to the prior quarter, totaling $10.1 billion as of June 30, 2023. The Company continues to exercise a disciplined approach to lending, carefully underwriting loans to strict underwriting guidelines and setting high expectations for risk adjusted returns given the current environment.

•Loan originations were $518.9 million in the second quarter of 2023, a decrease of 3% compared to $536.3 million in the first quarter of 2023.

•Commercial originations were $317.4 million during the second quarter of 2023, compared to $321.7 million in the first quarter of 2023, and $461.9 million in the second quarter of 2022.

•Consumer originations in the second quarter of 2023 were $97.2 million, compared to $110.6 million in the first quarter of 2023, and $130.8 million in the second quarter of 2022.

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

•Residential loans originated for sale in the secondary market totaled $19.1 million in the second quarter of 2023, compared to $13.9 million in the first quarter of 2023, and $42.7 million in the second quarter of 2022.

•Closed residential loans retained in the portfolio totaled $85.3 million in the second quarter of 2023, compared to $90.1 million in the first quarter of 2023, and $103.0 million in the second quarter of 2022.

•Pipelines (loans in underwriting and approval or approved and not yet closed) totaled $284.6 million on June 30, 2023, a decrease of 27% from March 31, 2023, and a decrease of 54% from June 30, 2022.

•Commercial pipelines were $217.6 million as of June 30, 2023, a decrease of 27% from $297.4 million at March 31, 2023, and a decrease of 54% from $476.7 million at June 30, 2022. The decline in pipeline quarter over quarter was the result of the impact of higher rates and a continued selective approach on new credit facilities given a cautious economic outlook.

•Consumer pipelines were $28.4 million as of June 30, 2023, a decrease of $10.3 million from $38.7 million at March 31, 2023, and a decrease of 62% from $75.5 million at June 30, 2022.

•Residential saleable pipelines were $11.5 million as of June 30, 2023, compared to $6.6 million at March 31, 2023, and $14.7 million at June 30, 2022. Retained residential pipelines were $27.1 million as of June 30, 2023, compared to $48.4 million at March 31, 2023, and $53.1 million at June 30, 2022.

•Total deposits were $12.3 billion as of June 30, 2023, a decrease of $26.4 million when compared to March 31, 2023, and an increase of $3.1 billion, or 34%, compared to June 30, 2022. Seacoast’s granular, longstanding deposit base is a hallmark of our franchise, and in the current environment serves as a significant source of strength. The Company continues to maintain balance sheet flexibility and ended the quarter with a loan to deposit ratio of 82%.

•At June 30, 2023, transaction account balances represented 57% of overall deposits.

•Noninterest bearing demand deposits represent 34% of overall deposits.

•Average deposits per banking center were $157 million at June 30, 2023 compared to $148 million at March 31, 2023.

•Uninsured deposits represented only 34% of overall deposit accounts as of June 30, 2023. This includes public funds under the Florida Qualified Public Depository program, which provides loss protection to depositors beyond FDIC insurance limits. Excluding such balances, the uninsured and uncollateralized deposits were 28% of total deposits. The Company has liquidity sources including cash and lines of credit with the Federal Reserve and Federal Home Loan Bank that represent 155% of uninsured deposits, and 184% of uninsured and uncollateralized deposits.

•Consumer deposits represent 43% of overall deposit funding with an average consumer customer balance of $23 thousand. Commercial deposits represent 57% of overall deposit funding with an average business customer balance of $109 thousand.

•Federal Home Loan Bank advances totaled $160.0 million at June 30, 2023 with a weighted average interest rate of 3.64%. In the aggregate, borrowed funds, including FHLB advances, subordinated debt, and brokered deposits represented only 6.6% of total liabilities as of June 30, 2023.

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 were $48.3 million at June 30, 2023. Nonperforming loans to total loans outstanding were 0.48% at June 30, 2023, 0.50% at March 31, 2023, and 0.40% at June 30, 2022.

•Nonperforming assets to total assets decreased to 0.37% at June 30, 2023, compared to 0.38% at March 31, 2023, and increased from 0.27% at June 30, 2022.

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

sbcflogoa.gif

•The ratio of allowance for credit losses to total loans was 1.58% at June 30, 2023, 1.54% at March 31, 2023, and 1.39% at June 30, 2022.

•Net charge-offs of $0.7 million for the second quarter of 2023 compared to $3.2 million in the first quarter of 2023 and compared to a net recovery of $0.1 million in the second quarter of 2022. Net charge-offs for the four most recent quarters averaged 0.06%.

•Portfolio diversification, in terms of asset mix, industry, and loan type, has been a critical element of the Company's lending strategy.

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.

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 Banking Corporation of Florida (“Seacoast” or the “Company”) or its wholly-owned banking subsidiary, Seacoast National Bank (“Seacoast Bank”), to be materially different from 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.

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, changes in 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 and credit risk as a result of the foregoing; potential impacts of the recent adverse developments in the banking industry highlighted by high- profile bank failures, including impacts on customer confidence, deposit outflows, liquidity and the regulatory response thereto; 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 and the possibility that the U.S. could default on its debt obligations; 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; changes in accounting policies, rules and practices; 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; Seacoast’s 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 decline in stock market prices on our fee income from our wealth management business; 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; fraud or misconduct by internal or external, which Seacoast may not be able to prevent, detect or mitigate; 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, including hurricanes in the Company’s footprint, 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; risks related to environmental, social and governance (“ESG”) matters, the scope and pace of which could alter Seacoast’s reputation and shareholder, associate, customer and third-party affiliations; the risks relating to bank acquisitions including the the merger with Professional Holding Corp. including, without limitation: the diversion of management's time on issues related to the merger; unexpected transaction costs, including the costs of integrating operations;

Excluding the effect of accretion on acquired loans, yields increased 16 basis points to 5.33%. • The cost of deposits increased 61 basis points to 1.38%, primarily the result of higher short term interest rates, and an increasingly competitive deposit market. 1Calculated on a fully taxable equivalent basis using amortized cost.

26SECOND QUARTER 2023 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.
