Pine Bluff, AR – Simmons First National Corporation (NASDAQ: SFNC) (the “Company” or “Simmons”) today reported net income of $74.9 million for the second quarter of 2021 compared to net income of $58.8 million for the second quarter of 2020, an increase of $16.1 million, or 27 percent. Diluted earnings per share for the second quarter of 2021 were $0.69, an increase of $0.15, or 28 percent, compared to the same period in the prior year. Included in second quarter 2021 results were $524,000 in net after-tax merger-related and net branch right-sizing costs. Excluding the impact of these items, core earnings were $75.4 million for the second quarter of 2021, compared to $60.1 million for the second quarter of 2020, an increase of $15.3 million, or 25 percent. Core diluted earnings per share were $0.69, an increase of $0.14, or 25 percent, from the comparable period in 2020.

On a year-to-date basis, net income for the first half of 2021 was $142.3 million, or $1.31 diluted earnings per share, compared to $136.0 million, or $1.22 diluted earnings per share, for the first half of 2020. Excluding $2.9 million in net after-tax merger-related and net branch right-sizing costs and the after-tax gain primarily associated with the sale of branches in Illinois, core earnings for the first half of 2021 were $139.4 million, an increase of $5.4 million compared to the first half of last year. Core diluted earnings per share for the first half of 2021 were $1.28, an increase of $0.07, or 6 percent, from the comparable period of 2020.

“Overall we were very pleased with our results for the quarter as we delivered solid performance in multiple areas while continuing to navigate the challenging environment,” said George A, Makris, Jr., Simmons’ chairman and CEO. “While loan growth throughout the financial services industry continues to be hampered by the significant amounts of government stimulus in the economy that has resulted in sluggish loan demand and historically high levels of paydowns, Simmons generated $1.8 billion in loan originations and advances during the first half of 2021, putting us on pace to significantly exceed loan production volume reported for the full-year of 2020. Our commercial loan pipeline has increased for three consecutive quarters and we are cautiously optimistic that this trend is a positive sign going forward.”

“At the same time, asset quality metrics continued to improve as certain initially anticipated impacts of the COVID-19 pandemic on asset quality have thus far failed to materialize. As such, we recorded the recapture of $13.0 million of provision expense during the quarter while maintaining our nonperforming loan coverage ratio and an appropriate allowance to loan ratio that is reflective of the uncertainty in the economy and associated risk in our loan portfolio. As a result of our solid results in the quarter and our strong asset quality and capital positions, Simmons’ board of directors extended and increased the authorization under our share repurchase program, thus increasing our remaining capacity under the program to approximately $150 million and extending the program’s scheduled expiration to October 2022.”

Loans

($ in billions) | 2nd Qtr 2021 | 1st Qtr 2021 | 2nd Qtr 2020
Total loans | $11.4 | $12.2 | $14.6

Total loans at the end of the second quarter of 2021 were $11.4 billion compared to $12.2 billion at the end of the first quarter of 2021 and $14.6 billion at the end of the second quarter of 2020. Total loan production (loan originations and advances) for the first half of 2021 totaled $1.8 billion. While loan originations and advances are outpacing prior year production, the decline in loan balances reflects the substantial government stimulus to support the economy during the COVID-19 pandemic which contributed to an increase in the level of loan paydowns, payoffs and corresponding sluggish loan demand throughout the financial services industry. The Company’s balance of Paycheck Protection Program (“PPP”) loans totaled $441.4 million at the end of the second quarter of 2021, down $463.3 million during the first half of 2021 as originations under PPP Round 2 have been offset by loan forgiveness.

Despite these headwinds, loan demand appears to be returning to more normalized levels. For the third consecutive quarter, the Company experienced an increase in its commercial loan demand. The Company’s total commercial loan pipeline consisting of all loan opportunities was $1.3 billion compared to $674 million at December 31, 2020. Loans approved and ready to close at the end of the quarter totaled $467 million.

Deposits

($ in billions) | 2nd Qtr 2021 | 1st Qtr 2021 | 2nd Qtr 2020
Total deposits | $18.3 | $18.2 | $16.6
Noninterest bearing deposits | $4.9 | $4.9 | $4.6
Interest bearing deposits | $10.6 | $10.3 | $9.0
Time deposits | $2.8 | $3.0 | $3.0

Total deposits at the end of the second quarter of 2021 were $18.3 billion, an increase of $1.7 billion or 10 percent from $16.6 billion at the end of the second quarter of 2020. The increase in total deposits from a year ago was driven by a $1.6 billion increase in interest bearing deposits (checking, savings and money market accounts) which totaled $10.6 billion at the end of the second quarter of 2021. Noninterest bearing deposits also contributed to the year-over-year growth in total deposits, increasing $285.9 million or 6 percent while time deposits declined $188.9 million or 6 percent during the same period.

Net Interest Income

| 2nd Qtr 2021 | 1st Qtr 2021 | 4th Qtr 2020 | 3rd Qtr 2020 | 2nd Qtr 2020
Loan yield (1) | 4.73% | 4.75% | 4.74% | 4.54% | 4.84%

Core net interest margin (1) (2) | 2.78% | 2.86% | 3.04% | 3.02% | 3.18%

| (1) | Fully tax equivalent using an effective tax rate of 26.135%.

| (2) | Core loan yield and core net interest margin exclude accretion and are non-GAAP measurements. Please see “Non-GAAP Financial Measures” and “Reconciliation of Non-GAAP Financial Measures” below.

| (3) | Includes non-interest bearing deposits.

Net interest income for the second quarter of 2021 totaled $146.5 million, compared to $146.7 million in the first quarter of 2021 and $163.7 million in the second quarter of 2020. Included in net interest income is accretion recognized on loans acquired totaling $5.6 million in the second quarter of 2021, $6.6 million in the first quarter of 2021 and $11.7 million in the second quarter of 2020. Excluding the impact of accretion, core net interest income for the second quarter of 2021 increased 1 percent on a linked quarter basis.

The decrease in net interest income from the year ago quarter reflects a lower average loan balance combined with an 11 basis point decrease in loan yields. To offset the expected pressure on net interest income given the current low interest rate environment, the Company has been diligent in its efforts to reduce deposits costs. As a result, cost of deposits for the second quarter of 2021 was 24 basis points, down 6 basis points on a linked quarter basis and 20 basis points compared to the second quarter of 2020.

While loan yields declined from the year ago quarter, on a linked quarter basis loan yields declined only 2 basis points. The core loan yield, which excludes accretion, for the second quarter of 2021 was 4.54 percent, up 1 basis point compared to the first quarter of 2021 and up 2 basis points compared to the second quarter a year ago. The yield on PPP loans was approximately 5.08 percent during the second quarter of 2021 (including accretion of net fees), which increased the overall loan yield by approximately 2 basis points.

The net interest margin on a fully taxable equivalent basis was 2.89 percent for the second quarter of 2021 compared to 2.99 percent for the first quarter of 2021 and 3.42 percent for the second quarter of 2020. Core net interest margin (excluding accretion on acquired loans) was 2.78 percent compared to 2.86 percent for the first quarter of 2021 and 3.18 percent for the second quarter of 2020. During the second quarter of 2021, the Company purchased $2.5 billion of investment securities. This included the strategic redeployment of excess liquidity through the purchase of variable rate investment securities totaling approximately $1.1 billion. Consequently, the duration of the investment securities portfolio shortened from 6.5 years at March 31, 2021 to 4.9 years at June 30, 2021.

Noninterest Income

Noninterest income for the second quarter of 2021 was $47.9 million compared to $50.3 million in the first quarter of 2021 and $48.8 million in the second quarter of 2020. Gains on the sale of investment securities totaled $5.1 million in the second quarter of 2021, $5.5 million in the first quarter of 2021 and $390,000 in the second quarter of 2020. Core noninterest income totaled $47.5 million in the second quarter of 2021 compared to $44.9 million in the first quarter of 2021 and $46.6 million in the second quarter of 2020. Core noninterest income excludes gains on the sale of branches which totaled $445,000 in the second quarter of 2021, $5.5 million in the first quarter of 2021 and $2.2 million in the second quarter of 2020.

Excluding these items, core noninterest expense was $114.3 million for the second quarter of 2021, $112.9 million for the first quarter of 2021 and $112.1 million for the second quarter of 2020.

Asset quality metrics continued to show marked improvement during the quarter. Total nonperforming loans at the end of the quarter totaled $80.9 million, down $34.6 million compared to $115.5 million at the end of the first quarter of 2021 and down $50.9 million from the second quarter of 2020. Net charge-offs as a percentage of average total loans for the quarter were negative 7 basis points, reflecting $2.2 million of loan charge-offs completely offset by $4.3 million of recoveries. Provision for credit losses in the quarter was a credit of $13 million, including $10 million associated with the loan portfolio. The recapture of provision for credit losses reflected continued positive trends in asset quality metrics, combined with improved economic modeling scenarios. As a result, the allowance for credit losses at the end of the second quarter of 2021 totaled $227.2 million compared to $235.1 million at the end of the first quarter of 2021 and $231.6 million at the end of the second quarter of 2020.

Share Repurchase Program

The Company’s board of directors approved an amendment to the Company’s stock repurchase program (“Program”) that increases the amount of the Company’s common stock that may be repurchased under the Program from a maximum of $180 million to a maximum of $276.5 million and extends the term of the Program from October 31, 2021, to October 31, 2022 (unless terminated sooner). The Program was originally approved on October 17, 2019 and amended in March 2020, and to date, the Company has repurchased approximately $126.5 million of its common stock under the Program.

The Program permits the Company to repurchase shares of its common stock through open market and privately negotiated transactions or otherwise. The timing, pricing, and amount of any repurchases under the Program will be determined by the Company’s management at its discretion based on a variety of factors, including, but not limited to, trading volume and market price of the common stock, corporate considerations, the Company’s working capital and investment requirements, general market and economic conditions, and legal requirements. The Program does not obligate the Company to repurchase any common stock and may be modified, discontinued, or suspended at any time without prior notice.

Non-GAAP Financial Measures

This press release contains financial information determined by methods other than in accordance with U.S. generally accepted accounting principles (“GAAP”). The Company’s management uses these non-GAAP financial measures in their analysis of the Company’s performance. These measures adjust GAAP performance measures to, among other things, include the tax benefit associated with revenue items that are tax-exempt, as well as exclude from income available to common shareholders, non-interest income, and non-interest expense certain income and expenses related to significant non-core activities, including merger-related expenses, gain on sale of branches, early retirement program expenses and net branch right-sizing expenses. In addition, the Company also presents certain figures based on tangible common stockholders’ equity, tangible assets and tangible book value, which exclude goodwill and other intangible assets. The Company further presents certain figures that are exclusive of the impact of PPP loans. The Company’s management believes that these non-GAAP financial measures are useful to investors because they, among other things, present the results of the Company’s ongoing operations without the effect of mergers or other items not central to the Company’s ongoing business, as well as normalize for tax effects. Management, therefore, believes presentations of these non-GAAP financial measures provide useful supplemental information that is essential to a proper understanding of the operating results of the Company’s core businesses, and management uses these non-GAAP financial measures to assess the performance of the Company’s core businesses as related to prior financial periods. These non-GAAP disclosures should not be viewed as a substitute for operating results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Where non-GAAP financial measures are used, the comparable GAAP financial measure, as well as the reconciliation to the comparable GAAP financial measure, can be found in the tables of this release.
