Spirit Of Texas Bancshares, Inc. Reports Fourth Quarter 2019 Financial Results

Organic loan growth of $35.9 million for the quarter

CONROE, Texas, Jan. 29, 2020 /PRNewswire/ —Spirit of Texas Bancshares, Inc.(NASDAQ: STXB)(“Spirit” or the “Company”), reported net income of $6.2 million in the fourth quarter of 2019 representing diluted earnings per share of $0.35. Net income and diluted earnings per share increased over the same period in the prior year by 148% and 59%, respectively.

Fourth Quarter 2019 Financial and Operational Highlights

• Successfully completed the acquisition of Chandler Bancorp, Inc. and its subsidiary, Citizens State Bank, (together, “Citizens”) on November 5, 2019. The acquisition added approximately $321 million of total assets and seven full-service branches serving the East Texas region.

• Strong organic loan growth of $35.9 million for the three months ended December 31, 2019, or 9.6% annualized.

• Return on average assets was 1.11% annualized, which was unchanged from prior quarter and a 33 basis point increase from the fourth quarter of 2018.

• At December 31, 2019, book value per share was $18.93 and tangible book value per share⁽¹⁾ was $14.56.

• At December 31, 2019, total stockholders’ equity to total assets was 14.50% and tangible stockholders’ equity to tangible assets⁽¹⁾ was 11.54%.

• Diluted earnings per share were $0.35 for the fourth quarter of 2019, compared to $0.22 for the fourth quarter of 2018. Adjusted diluted earnings per share⁽¹⁾ were $0.28 for the fourth quarter of 2019. Thepre-tax,non-GAAP adjustments for the fourth quarter of 2019 consisted of a $2.4 million gain on the sale of investment securities and $821 thousand in merger related expenses.

• Entered into a Branch Purchase and Assumption Agreement with Simmons Bank to purchase four branch offices and one mortgage loan office located in Austin, San Antonio and Tilden, Texas. The branch acquisition which will include related loan and deposit accounts is expected to close during the first quarter of 2020.

Dean Bass, Spirit’s Chairman and Chief Executive Officer, stated, “Our fourth quarter results continue to support and validate our acquisition and market diversification strategy across Texas. Since our IPO nearly two years ago, we will have expanded the Spirit’s presence from 15 locations to 41 locations after we close the Simmons branch acquisition this quarter. We continue to believe we are well positioned to take advantage of more opportunities in our markets, while providing the highest quality of service to our vibrant and growing customer base.”

Loan Portfolio and Composition

During the fourth quarter of 2019, gross loans grew to $1.77 billion as of December 31, 2019, an increase of 18.8% from $1.49 billion as of September 30, 2019, and an increase of 60.2% from $1.10 billion as of December 31, 2018. Loan growth during the fourth quarter of 2019 was primarily driven by the Citizens acquisition which added $247.3 million in loans to the acquired loan portfolio. During the third and fourth quarter of 2019, the Company executed strategic banker lift-outs that significantly contributed to the strong organic loan growth during the fourth quarter of $35.9 million. We expect these professionals will generate and maintain meaningful portfolios, while also continuing our focus on increasing core deposits to fund loan growth. We intend to continue to seek out talented bankers that are a good cultural fit and have long standing business relationships in our markets to continue to drive organic loan growth.

Additionally, with the Simmons branch acquisitions, we will expand our presence into the dynamic Austin market and strengthen our presence in the SanAntonio-New Braunfels market. The acquisition will provide a strong loan portfolio and deposit base and will complement our franchise. Completion of this transaction, which is expected in the first quarter of 2020, will allow us to expand our footprint to serve all major Texas metropolitan areas.

Asset Quality

Asset quality continued to remain strong in the fourth quarter of 2019. The provision for loan losses recorded for the fourth quarter of 2019 was $775 thousand which served to increase the allowance to $6.7 million, or 0.38% of the $1.77 billion in loans outstanding as of December 31, 2019. The coverage ratio on the organic portfolio was 0.57% of the $1.18 billion in organic loans outstanding as of December 31, 2019. The nonperforming loans to loans held for investment ratio as of December 31, 2019 decreased to 0.37% from 0.61% as of September 30, 2019, and 0.46% at December 31, 2018. Annualized net charge-offs were 14 basis points for the fourth quarter of 2019, compared to 22 basis points for the fourth quarter of 2018.

Deposits and Borrowings

Deposits totaled $1.93 billion as of December 31, 2019, an increase of 21.6% from $1.59 billion as of September 30, 2019, and an increase of 63.0% from $1.18 billion as of December 31, 2018. Noninterest-bearing demand deposits increased $78.6 million, or 21.5%, from September 30, 2019, and increased $188.0 million, or 73.2% from December 31, 2018. Noninterest-bearing demand deposits represented 23.1% of total deposits as of December 31, 2019, which was unchanged from September 30, 2019, and 21.7% of total deposits as of December 30, 2018. The average cost of deposits was 0.98% for the fourth quarter of 2019, representing a five basis point decrease from the third quarter of 2019 and a four basis point decrease from the fourth quarter of 2018.

Net Interest Margin and Net Interest Income

The net interest margin for the fourth quarter of 2019 was 4.39%, a decrease of 20 basis points from the third quarter of 2019 and from the fourth quarter of 2018. The tax equivalent net interest margin⁽¹⁾ for the fourth quarter of 2019 was 4.41%, a decrease of 22 basis points from the third quarter of 2019 and a decrease of 21 basis points from the fourth quarter of 2018. The decline from the third quarter of 2019 is primarily due to rate resets on interest-earning assets as a result of decreases in interest rates set by the Federal Open Market Committee during the third quarter of 2019.

Net interest income totaled $22.2 million for the fourth quarter of 2019, an increase of 60.3% from $13.9 million for the fourth quarter of 2018. Interest income totaled $27.1 million for the fourth quarter of 2019, an increase of 60.0% from $16.9 million in the same period in 2018. Interest and fees on loans increased by $9.3 million, or 59.1%, from the fourth quarter of 2018 due to organic and acquired growth in the loan portfolio. Interest expense was $4.9 million for the fourth quarter of 2019, an increase of 58.5% from $3.1 million for the same period in 2018. The increase from the fourth quarter of 2018 was primarily due to growth in the deposit base from acquisitions partially offset by a decrease in the rate paid on interest-bearing liabilities of six basis points.

Noninterest Income and Noninterest Expense

Noninterest income totaled $5.1 million for the fourth quarter of 2019, compared to $3.0 million for the fourth quarter of 2018. The primary components of noninterest income for the fourth quarter of 2019 were gain on sales of securities of $2.4 million, gain on sales of loans of $675 thousand, and net and service charges and fees of $1.1 million. Noninterest expense totaled $18.7 million in the fourth quarter of 2019, an increase of 37.5% from $13.6 million in the same period of the prior year. This increase was primarily driven by increased salaries and employee benefits resulting from the Citizen’s acquisition as well as an investment in strategic banker lift-outs and the amortization of core deposit intangibles related to the acquisitions of The Comanche National Bank, The First National Bank of Beeville, and Citizens.

The efficiency ratio was 68.40% in the fourth quarter of 2019, compared to 80.36% in the fourth quarter of 2018.

(1) Adjusted Basic and Diluted Earnings Per Share, Tax Equivalent Net Interest Margin, Tangible Book Value Per Share, and Tangible Stockholders’ Equity to Tangible Assets Ratio are allnon-GAAP measures. Spirit believes that for Adjusted Basic and Diluted Earnings Per Share, the adjustments made to net income allow investors and analysts to better assess its basic and diluted earnings per common share by removing the volatility that is associated with merger-related expenses and gain on sale of investment securities that are unrelated to its core business. 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 andtax-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. Thenon-GAAP financial measures that we discuss in this news 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 thenon-GAAP financial measures that it discusses in this news 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 thenon-GAAP financial measures Spirit has discussed in this news release when comparing suchnon-GAAP financial measures. Please see a reconciliation to the nearest respective GAAP measures at the end of this news release.
