SPIRIT OF TEXAS BANCSHARES, INC. REPORTS

FOURTH QUARTER 2021 FINANCIAL RESULTS

CONROE, TX – January 26, 2022 – Spirit of Texas Bancshares, Inc. (NASDAQ: STXB) (“Spirit,” the “Company,” “we,” “our,” or “us”), reported net income of $9.1 million in the fourth quarter of 2021, representing diluted earnings per share of $0.51, compared to net income of $12.5 million in the fourth quarter of 2020, representing diluted earnings per share of $0.72. During the fourth quarter of 2020, net income was impacted by $3.7 million in gain on sale of Main Street Lending loans and $4.5 million in net accretion of deferred origination fees on Paycheck Protection Program (“PPP”) loans forgiven by the U.S. Small Business Administration (“SBA”), compared to the fourth quarter of 2021 which only had $1.5 million in net accretion of deferred origination fees on PPP loans. Additionally, the fourth quarter of 2021 contained $800 thousand of expenses related to the proposed merger with Simmons First Financial Corporation (“Simmons”) and $412 thousand of expenses related to normal bonus payments that will be accelerated to the proposed acquisition close date.

Fourth Quarter 2021 Financial and Operational Highlights

• On November 19, 2021, Spirit announced its intention to merge with Simmons with expectations to close the transaction during the second quarter of 2022, subject to the receipt of Spirit shareholder approval, regulatory approvals and waivers and other customary closing conditions.

• Excluding the impact of PPP loan forgiveness by the SBA during the period, loans held for investment increased 24.3% annualized for the three months ended December 31, 2021.

• Net interest margin for the fourth quarter of 2021 as reported and on a tax equivalent basis⁽¹⁾ was 3.87% and 3.89%, respectively.

• At December 31, 2021, return on average assets was 1.13% on an annualized basis.

• Book value per share increased to $22.79 and tangible book value per share⁽¹⁾ increased to $18.02 at December 31, 2021, compared to $22.49 and $17.67, respectively, at September 30, 2021.

• Total stockholders’ equity to total assets was 12.06% and tangible stockholders’ equity to tangible assets⁽¹⁾ was 9.78% at December 31, 2021.

• Capital ratios remained strong with Common Equity Tier 1 ratio at the Company and the Bank of 10.64% and 10.65%, respectively, at December 31, 2021.

“As we continue to work toward the upcoming completion of the proposed merger with Simmons, I am pleased to report another exceptional quarter of financial and operational success.” Dean Bass, Spirit’s Chairman and Chief Executive Officer, stated. “While we have enjoyed seeing the return of loan demand over the past few quarters in the form of a larger loan pipeline, the fourth quarter of 2021 saw an impressive move in volume from the pipeline to closed and funded loans. We are also excited to see SBA loan sales during the quarter which translated into $811 thousand in gain on sale of loans during the fourth quarter of 2021. Both robust loan demand and the return of higher non-interest revenue streams represent great opening acts to the start of our anticipated next chapter merging with Simmons.

“I am exceptionally proud of what our team has been able to accomplish over the past twelve years and I’m excited to see what heights we can reach partnering with a best-in-class regional bank,” Mr. Bass concluded.

Loan Portfolio and Composition

During the fourth quarter of 2021, gross loans increased to $2.32 billion as of December 31, 2021, an increase of 3.08% from $2.25 billion as of September 30, 2021, and a decrease of 2.78% from $2.39 billion as of December 31, 2020. PPP loan forgiveness, which has been the primary cause of the overall decrease in loans year over year, will not significantly impact loan growth going forward as only 237 PPP loans remain outstanding with a total recorded investment of $43.9 million as of December 31, 2021. Excluding the effect of PPP loan forgiveness, the loan portfolio as of December 31, 2021 increased by $131.6 million, or 24.3% annualized from September 30, 2021. Despite a large volume of loans moving from the pipeline to closed loans, the remaining pipeline is well over $1.0 billion and represents an exciting opportunity to fund additional projects in the coming quarters.

Asset Quality

Asset quality is strong with loans continuing to migrate into lower risk ratings during the fourth quarter of 2021 and with non-performing loans declining $855 thousand or 13.9% from the third quarter of 2021. We perceive the sentiment in the Texas economy to be optimistic despite continued labor and supply shortages and higher inflation that may persist longer than previously expected. The provision for loan losses recorded for the fourth quarter of 2021 was $970 thousand, which served to increase the allowance to $16.4 million, or 0.71% of the $2.32 billion in gross loans outstanding as of December 31, 2021. Provision expense for the fourth quarter of 2021 related primarily to the provisioning of new loans.

As of December 31, 2021, the nonperforming loans to loans held for investment ratio remains low at 0.22%, a decrease from 0.28% at September 30, 2021, and a decrease from 0.36% as of December 31, 2020. Annualized net charge-offs were 15 basis points for the fourth quarter of 2021 compared to 10 basis points for the third quarter of 2021.

Deposits and Borrowings

Deposits totaled $2.78 billion as of December 31, 2021, an increase of 4.2% from $2.67 billion as of September 30, 2021, and an increase of 13.2% from $2.46 billion as of December 31, 2020. Noninterest-bearing demand deposits increased $36.1 million, or 4.70%, from September 30, 2021, and increased $76.0 million, or 10.5%, from December 31, 2020. Noninterest-bearing demand deposits represented 28.9% of total deposits as of December 31, 2021, up from 28.7% of total deposits as of September 30, 2021, and down from 29.6% of total deposits as of December 31, 2020. Interest-bearing deposits, including money market and savings as of December 31, 2021 increased $96.6 million, or 29.1% annualized from September 30, 2021, primarily due to success in retaining and growing client relationships from COVID-19 related assistance programs. Growth in interest-bearing deposits was slightly offset by a decrease in time deposits of $20.9 million, or 3.6%, from September 30, 2021. The average cost of deposits was 0.22% for the fourth quarter of 2021, representing a 3 basis point decrease from the third quarter of 2021 and a 21 basis point decrease from the fourth quarter of 2020.

2

Borrowings decreased by $4.3 million during the fourth quarter of 2021 to $74.9 million, due primarily to the repayment of maturing Federal Home Loan Bank (“FHLB”) advances. At December 31, 2021, we did not have any remaining borrowings under the Paycheck Protection Program Liquidity Facility with the Board of Governors of the Federal Reserve System (“PPPLF”). Borrowings totaled 2.3% of total assets at December 31, 2021, compared to 2.5% at September 30, 2021 and 8.2% at December 31, 2020.

Net Interest Margin and Net Interest Income

The net interest margin for the fourth quarter of 2021 was 3.87%, a decrease of 5 basis points from the third quarter of 2021 and a decrease of 49 basis points from the fourth quarter of 2020. The tax equivalent net interest margin⁽¹⁾ for the fourth quarter of 2021 was 3.89%, a decrease of 11 basis points from the third quarter of 2021 and a decrease of 55 basis points from the fourth quarter of 2020. The decline in net interest margin is primarily due to the increase in average cash balances. Approximately $979 thousand of net deferred SBA fees related to PPP loans remain unamortized at December 31, 2021. The yield on loans for the fourth quarter of 2021 was 5.08% compared to 5.09% at September 30, 2021 and 5.42% at December 21, 2020.

Net interest income totaled $28.5 million for the fourth quarter of 2021, an increase of 1.3% from $28.1 million for the third quarter of 2021 and a decrease of 4.7% from $29.9 million for the fourth quarter of 2020. Interest income totaled $30.8 million for the fourth and third quarters of 2021, compared to $33.7 million for the fourth quarter of 2020. Interest and fees on loans increased $218 thousand, or 0.75%, compared to the third quarter of 2021, and decreased by $3.5 million, or 10.8%, from the fourth quarter of 2020. Interest expense was $2.4 million for the fourth quarter of 2021, a decrease of 10.8% from $2.7 million for the third quarter of 2021 and a decrease of 38.1% from $3.8 million for the fourth quarter of 2020.

Noninterest Income and Noninterest Expense

Noninterest income totaled $4.3 million for the fourth quarter of 2021, compared to $3.3 million for the third quarter of 2021 and $8.8 million for the fourth quarter of 2020. This increase from the third quarter of 2021 was primarily driven by higher SBA loan servicing fees and a gain on sale of loans.

Noninterest expense totaled $20.3 million in the fourth quarter of 2021, an increase of 12.6 % from $18.0 million in the third quarter of 2021, which was primarily due to increases in salaries and benefits expense and professional services. The increase in salaries and benefits expense for the quarter was due to $412 thousand of normal bonus payments that will be accelerated to the close date of the proposed merger with Simmons.

The efficiency ratio was 61.9% in the fourth quarter of 2021, compared to 57.5% in the third quarter of 2021, and 47.7% in the fourth quarter of 2020. The fourth quarter of 2021 efficiency ratio was negatively impacted during the quarter by the aforementioned additional salaries and benefits expense.

(1) Tax Equivalent Net Interest Margin, Tangible Book Value Per Share, Tangible Stockholders’ Equity to Tangible Assets Ratio and certain PPP-related figures are all non-GAAP measures. In Spirit’s judgment, regarding Tax Equivalent Net Interest Margin, the fully tax equivalent basis is the preferred industry measurement basis for net interest margin and that it enhances comparability of net interest income arising from taxable and tax-exempt sources. Regarding Tangible Book Value Per Share and Tangible Stockholders’ Equity To Tangible Assets, Spirit believes that that these measures are important to many investors in the marketplace who are interested in changes from period to period in book value per share exclusive of changes in intangible assets. Goodwill and other intangible assets have the effect of increasing total book value while not increasing its tangible book value. Furthermore, Spirit believes that the PPP-related figures are important to investors due to the anticipated short-term nature of the PPP loans and the expected forgiveness in the coming quarters. The non-GAAP financial measures that we discuss in this earnings release should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Moreover, the manner in which we calculate the non-GAAP financial measures discussed in this earnings release may differ from that of other banking organizations reporting measures with similar names. You should understand how such other banking organizations calculate their financial measures similar or with names similar to the non-GAAP financial measures Spirit has discussed in this earnings release when comparing such non-GAAP financial measures. Please see a reconciliation to the nearest respective GAAP measures at the end of this earnings release.
