This transaction strengthens our California presence with a pro forma asset base of $3.8 billion. I am excited about how this adds to our expected growth prospects and diversification of our business, particularly in close proximity to the successful first quarter core systems integration for Seacoast. We are off to a solid start in 2021, with earnings of $0.96 per share and continued execution on the Paycheck Protection Program (“PPP”) for the benefit of our customers. In addition, we issued our inaugural Environmental, Social and Governance report during March. I am pleased that we have taken the first step in reporting our ESG efforts and demonstrating the importance of our ESG objectives in meeting our mission.”

Highlights

• Earnings - Net income in the first quarter 2021 was $29.9 million, an increase of $1.0 million compared to the linked quarter and an increase of $17.1 million from the prior year quarter. EPS was $0.96 per diluted share for the first quarter 2021, compared to $1.00 and $0.48 per diluted share for the linked and prior year quarters, respectively. Merger-related expenses from the Seacoast transaction reduced net income $2.4 million, or $0.07 per share. The increase in net income and EPS from the prior year quarter was primarily due to a decrease of $22.2 million in the provision for credit losses.

• Pre-provision net revenue¹ (“PPNR”) - PPNR of $40.7 million in the first quarter 2021 decreased $6.8 million and increased $2.6 million from the linked and prior year quarters, respectively. The decrease from the linked quarter was primarily due to a decline in tax credit revenue and PPP fees. The increase from the prior year quarter was primarily from the Seacoast acquisition that was completed in the fourth quarter and income from PPP that started in the second quarter of 2020.

¹ PPNR is a non-GAAP measure. Refer to discussion and reconciliation of these measures in the accompanying financial tables.

• Net interest income and net interest margin (“NIM”) - Net interest income of $79.1 million for the first quarter 2021 increased $1.7 million and $15.8 million from the linked quarter and prior year quarter, respectively. NIM was 3.50% for the first quarter 2021, compared to 3.66% and 3.79% for the linked quarter and prior year quarter, respectively.

• Noninterest income - Noninterest income of $11.3 million for the first quarter 2021 decreased $7.2 million and $2.1 million from the linked quarter and prior year quarter, respectively. The decrease was primarily due to a decline in tax credit activity caused by delays in projects, which declined $5.1 million from the linked quarter and $3.1 million from the prior year quarter.

• Loans - Total loans increased $63.8 million, or 3.6% on an annualized basis, from the linked quarter to $7.3 billion as of March 31, 2021. Year-over-year, loans grew $1.8 billion, or 33.6% from $5.5 billion as of March 31, 2020, primarily due to Seacoast loans of $1.2 billion upon acquisition and PPP loans of $737.7 million. Average loans totaled $7.2 billion for the quarter ended March 31, 2021 compared to $6.8 billion and $5.4 billion for the linked and prior year quarters, respectively.

PPP details:

• Asset quality - The allowance for credit losses on loans to total loans was 1.80% at March 31, 2021, compared to 1.89% and 1.69% at December 31, 2020 and March 31, 2020, respectively. Nonperforming assets to total assets was 0.50% at March 31, 2021 compared to 0.45% and 0.56% at December 31, 2020 and March 31, 2020, respectively. The decline in the allowance to total loans ratio in the first quarter 2021 was primarily due to loan charge-offs of $6.5 million, the majority of which had been reserved for in a prior period. High-quality credit metrics, continued improvement in economic forecasts and relatively stable loan volumes resulted in a nominal provision for credit losses in the current quarter.

• Deposits - Total deposits increased $530.1 million, or 6.6%, from the linked quarter to $8.5 billion as of March 31, 2021. Year-over-year, deposits grew $2.5 billion, or 42.2%, from $6.0 billion as of March 31, 2020. Average deposits totaled $8.2 billion for the quarter ended March 31, 2021 compared to $7.3 billion and $5.8 billion for the linked and prior year quarters, respectively. Deposits from the Seacoast acquisition and PPP loans contributed to the increase over the prior year period. Specialty deposits increased $163.4 million over the linked quarter primarily attributable to community associations and sponsor finance. The St. Louis, Kansas City, and New Mexico regions also experienced significant growth of $132.5 million, $129.3 million, and $77.5 million, respectively, over the linked quarter. Noninterest deposit accounts represented 34.2% of total deposits and the loan to deposit ratio was 85.6% at March 31, 2021.

• Capital - Total shareholders’ equity was $1.1 billion and the tangible common equity to tangible assets ratio was 8.2% at March 31, 2021, compared to 8.4% at December 31, 2020. The Bank’s regulatory capital ratios remain “well-capitalized,” with a common equity tier 1 ratio of 12.4% and a total risk-based capital ratio of 13.6% as of March 31, 2021. The Company’s common equity tier 1 ratio and total risk-based capital ratio was 11.0% and 15.1%, respectively, at March 31, 2021.

The Company has 95,907 shares available for repurchase under the existing common stock repurchase authorization.

The Company’s Board of Directors approved a quarterly dividend of $0.18 per common share, payable on June 30, 2021 to shareholders of record as of June 15, 2021.

• Liquidity - The Company maintains a high level of both on-balance-sheet and off-balance-sheet liquidity. At March 31, 2021, on-balance-sheet liquidity consisted of cash and unpledged investment securities of $1.0 billion. Off-balance-sheet liquidity totaled $1.8 billion through the Federal Home Loan Bank, Federal Reserve and correspondent bank lines. The Company also has an unused $25 million revolving line of credit and maintains a shelf registration allowing for the issuance of various forms of equity and debt securities.

Net Interest Income

Average Balance Sheets

The following table presents, for the periods indicated, certain information related to our average interest-earning assets and interest-bearing liabilities, as well as, the corresponding interest rates earned and paid, all on a tax-equivalent basis.

Net interest income for the first quarter increased $1.7 million to $79.1 million from $77.4 million in the linked quarter, and increased $15.8 million from the prior year period. NIM, on a tax equivalent basis, was 3.50% for the first quarter, compared to 3.66% in the linked quarter, and 3.79% in the first quarter of 2020. The increase in net interest income from the linked quarter was primarily due to the full quarter of earnings on acquired Seacoast assets and lower interest expense on paying liabilities, partially offset by reduced income from PPP loans and purchase accounting adjustments.

NIM decreased 16 basis points from the linked quarter to 3.50% during the current quarter primarily due to a 21 basis point decrease in earning asset yields. The decrease in the earning asset yield was primarily due to higher levels of cash related to PPP funds and deposit growth (13 bps), reduced income from PPP forgiveness (11 bps) and lower levels of accretion from purchase accounting (5 bps), partially offset by the full-quarter impact of acquired Seacoast assets (8 bps).

The cost of interest-bearing liabilities declined seven basis points from the linked quarter, primarily due to the full-quarter impact of lower cost deposits from Seacoast, lower rates on time deposits, and a reduction in expense on borrowings.

Loans

The following table presents total loans for the most recent five quarters:

Loans totaled $7.3 billion at March 31, 2021, increasing $63.8 million, or 3.6% on an annualized basis, compared to the linked quarter. Year-over-year, loans increased $1.8 billion, or 33.6%. The year-over-year increase was primarily due to the Seacoast acquisition and PPP loans. The largest growth categories, excluding PPP, compared to the linked quarter were investor-owned CRE, SBA, other, life insurance premium finance, and tax credits. Line draw utilization continues to decline. For the quarter ended March 31, 2021 average line draw utilization was 37.0% compared to 38.1% and 47.3% for the linked quarter and prior-year quarter, respectively.

Asset Quality

The following table presents the categories of nonperforming assets and related ratios for the most recent five quarters:

Nonperforming loans decreased $1.8 million to $36.7 million at March 31, 2021 from $38.5 million at December 31, 2020. Activity during the current quarter primarily included additions of $6.2 million, reductions of $1.6 million, and charge-offs of $6.5 million. The addition of $6.2 million during the quarter was primarily from a $4.2 million retail relationship that went on nonaccrual. Other real estate increased during the first quarter 2021 due to one addition of $1.2 million partially offset by sales of $0.4 million.

The Company recorded a provision for credit losses of $46.3 thousand for the first quarter 2021 compared to $9.5 million for the linked quarter and $22.3 million for the prior year quarter. While the majority of the charge-offs in the quarter were reserved for in a prior period, a provision of approximately $3.0 million was recognized on a retail loan that defaulted in the quarter. The impact on the provision for credit losses of this loan was offset by an improvement in the economic forecast, net of qualitative adjustments.

Deposits

The following table presents deposits broken out by type for the most recent five quarters:

Total deposits at March 31, 2021 were $8.5 billion, an increase of $530.1 million from December 31, 2020, and an increase of $2.5 billion from March 31, 2020.

Core deposits, defined as total deposits excluding certificates of deposits, were $8.0 billion at March 31, 2021, an increase of $558.8 million from the linked quarter. The Company’s participation in PPP continues to contribute to the increase in deposits. Money market and savings accounts increased $138.6 million compared to the linked quarter, while interest-bearing and noninterest-bearing deposits increased $221.8 million and $198.4 million, respectively. Noninterest-bearing deposits were $2.9 billion at March 31, 2021, or 34.2% of total deposits. Certificates of deposit decreased $28.7 million from the linked quarter and $244.6 million from the prior year quarter. The total cost of deposits was 0.13% for the current quarter compared to 0.17% and 0.68% for the linked quarter and prior year quarter, respectively.

Noninterest Income

The following table presents a comparative summary of the major components of noninterest income for the periods indicated:

Total noninterest income for the first quarter 2021 was $11.3 million, a decrease of $7.2 million from the linked quarter and a decrease of $2.1 million from the prior year quarter. The decrease from the linked quarter and prior year quarter was primarily due to a decline in tax credit income. Several tax credit projects that were expected to close in the quarter were delayed and did not close. In addition, projects carried at fair value recognized a reduced valuation during the quarter due to an increase in the longer-term LIBOR swap rates used in the valuation process. The decline in miscellaneous income from the linked quarter was due to income earned on community development investments in the fourth quarter 2020 that did not reoccur in the current period.

Noninterest Expenses

Noninterest expense was $52.9 million for the first quarter 2021, compared to $51.1 million for the linked quarter, and $38.7 million for the first quarter 2020. The increase from the linked quarter and prior year quarter was primarily due to having a full quarter of Seacoast operations, which totaled $10.2 million in the first quarter 2021. Merger-related expenses were $3.1 million and $2.6 million in the current and linked quarters, respectively. The Company does not expect to incur any additional material merger expenses related to the Seacoast transaction.

For the first quarter 2021, the Company’s efficiency ratio was 58.5% compared to 53.2% and 50.4% for the linked quarter and prior year quarter, respectively. The Company’s core efficiency ratio² was 55.0% for the quarter ended March 31, 2021, compared to 50.9% for the linked quarter and 51.2% for the prior year quarter.

² Core efficiency ratio is a non-GAAP measure. Refer to discussion and reconciliation of this measure in the accompanying financial tables.

Income Taxes

The Company’s effective tax rate was 20% for the quarter ended March 31, 2021, compared to 18% in the linked quarter and 19% in the prior year quarter.

Capital

The following table presents various EFSC capital ratios:

The Company’s regulatory capital ratios continue to expand due to the Company’s earnings profile and manageable dividend payout ratio. The decline in the tangible common equity to tangible assets ratio was primarily due to continued growth in the balance sheet from PPP loans and the related deposit balances. Capital ratios for the current quarter are subject to, among other things, completion and filing of the Company’s regulatory reports and ongoing regulatory review.

Use of Non-GAAP Financial Measures

The Company’s accounting and reporting policies conform to generally accepted accounting principles in the United States (“GAAP”) and the prevailing practices in the banking industry. However, the Company provides other financial measures, such as tangible common equity, PPNR, PPNR ROAA, financial metrics adjusted for PPP impact, core efficiency ratio, and the tangible common equity ratio, in this release that are considered “non-GAAP financial measures.” Generally, a non-GAAP financial measure is a numerical measure of a company’s financial performance, financial position, or cash flows that exclude (or include) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP.

The Company considers its tangible common equity, PPNR, PPNR ROAA, financial metrics adjusted for PPP impact, core efficiency ratio, and the tangible common equity ratio, collectively “core performance measures,” presented in this earnings release and the included tables as important measures of financial performance, even though they are non-GAAP measures, as they provide supplemental information by which to evaluate the impact of certain non-comparable items, and the Company’s operating performance on an ongoing basis. Core performance measures exclude certain other income and expense items, such as merger-related expenses, facilities charges, and the gain or loss on sale of investment securities, the Company believes to be not indicative of or useful to measure the Company’s operating performance on an ongoing basis. The attached tables contain a reconciliation of these core performance measures to the GAAP measures. The Company believes that the tangible common equity ratio provides useful information to investors about the Company’s capital strength even though it is considered to be a non-GAAP financial measure and is not part of the regulatory capital requirements to which the Company is subject.

The Company believes these non-GAAP measures and ratios, when taken together with the corresponding GAAP measures and ratios, provide meaningful supplemental information regarding the Company’s performance and capital strength. The Company’s management uses, and believes that investors benefit from referring to, these non-GAAP measures and ratios in assessing the Company’s operating results and related trends and when forecasting future periods. However, these non-GAAP measures and ratios should be considered in addition to, and not as a substitute for or preferable to, ratios prepared in accordance with GAAP. In the attached tables, the Company has provided a reconciliation of, where applicable, the most comparable GAAP financial measures and ratios to the non-GAAP financial measures and ratios, or a reconciliation of the non-GAAP calculation of the financial measures for the periods indicated.
