First Quarter 2018 Financial Results

MOUNT PLEASANT, Texas, April 24, 2018 /GlobeNewswire/ -- Guaranty Bancshares, Inc. (NASDAQ: GNTY), the holding company for Guaranty Bank & Trust, N.A., today reported financial results for the fiscal quarter ended March 31, 2018. For the three months ended March 31, 2018, net earnings increased $843,000, or 24.0%, to $4.4 million from $3.5 million for the prior period. Basic earnings per share was $0.39 for the three months ended March 31, 2018 compared to $0.40 during the prior period. The company's earnings per share were impacted by the issuance of 2,300,000 shares of common stock in the company's initial public offering, which closed in May 2017.

The company's first quarter net earnings were impacted by approximately $200,000 in nonrecurring expenses related to the pending acquisition of Westbound Bank ("Westbound"). On January 29, 2018, Guaranty announced the execution of a definitive agreement providing for the proposed merger of Westbound with and into Guaranty Bank & Trust, which will facilitate Guaranty’s entry into the Houston metropolitan area.  Guaranty expects to close the merger during the second quarter of 2018, subject to the satisfaction of customary closing conditions and approval by Westbound’s shareholders.  Upon completion of the merger, Guaranty will continue to operate Westbound’s four locations in Katy, Bellaire, Houston and Conroe, Texas. Excluding the Westbound pending acquisition related expenses, basic earnings per share during the first quarter of 2018 would be $0.41 per basic share.

The first quarter 2018 growth in net earnings was primarily attributable to growth in net interest income of $1.1 million, an increase in noninterest income of $383,000, and a decrease in the income tax provision of $368,000. These increases were partially offset by an increase in noninterest expense of $1.1 million, which includes the Westbound merger related expenses described above, and expenses of $360,000 associated with our two new de novo branches that opened in the fourth quarter of 2017.

Net interest income for the first quarter of 2018 and 2017 was $15.4 million and $14.2 million, respectively, an increase of $1.1 million, or 7.9%. Net interest margin for the first quarter of 2018 and 2017 was 3.41% and 3.34%, respectively. Net interest income and net interest margin, on a taxable equivalent basis, were $15.4 million and 3.43%, respectively, for the first quarter of 2018.

The provision for loan losses was $600,000 in the first quarter of 2018, compared to $600,000 in the fourth quarter of 2017 and $650,000 in the first quarter of 2017. The provision for loan losses is primarily reflective of organic growth during the respective periods. Nonperforming assets as a percentage of total loans have remained consistent and were 0.64% at March 31, 2018, compared to 0.64% at December 31, 2017, and 0.66% at March 31, 2017.

Noninterest income increased 11.7% in the first quarter of 2018 to $3.7 million, compared to $3.3 million in the same quarter a year ago. Merchant and debit card fees increased 13.3% to $829,000, compared to $732,000 in the same quarter last year due to continued growth in net new accounts and debit cards. Gain on sale of mortgage loans increased $127,000, or 29.6%, from from $429,000 in the first quarter of 2017 to $556,000 in the current quarter. The increase in gain on sale of mortgage loans results from increases in the volume and amount of the loans sold. Other categories of noninterest income increased with the continued growth of the bank.

Noninterest expense for the first quarter of 2018 totaled $13.1 million, compared to $12.0 million for the first quarter of 2017, an increase of 9.0%. The increase in noninterest expense in the first quarter of 2018 was primarily driven by a $791,000 increase in salary and employee benefit expenses when compared to the same quarter a year ago, a $207,000 increase in legal and professional fees primarily associated with the pending Westbound acquisition and a $105,000 increase in occupancy expenses. Increases in salary and occupancy expenses were significantly impacted as a result of our two de novo locations in Austin and Fort Worth, Texas that were opened in the fourth quarter of 2017. The increase was partially offset by decreases in FDIC insurance expense of $35,000 and other non-interest expenses of $172,000. The company's efficiency ratio in the first quarter of 2018 was 68.99%, compared to 68.74% in the same quarter last year.

As of March 31, 2018, consolidated assets for the company totaled $2.00 billion, compared to $1.96 billion at December 31, 2017 and $1.90 billion at March 31, 2017. During the first quarter, gross loans increased 3.1%, or $41.8 million, to $1.40 billion at March 31, 2018, compared to loans of $1.36 billion at December 31, 2017. Gross loans increased 12.7%, or $157.4 million, from $1.25 billion at March 31, 2017. Deposits increased slightly during the first quarter by 0.9%, or $15.3 million, to $1.69 billion at March 31, 2018 compared to $1.68 billion at December 31, 2017. Total deposits increased 1.2%, or $20.4 million, from $1.67 billion at March 31, 2017. Deposit growth was impacted in the first quarter of 2018 by the loss of one large public funds

account that maintained an average balance of $20.0 million in deposits with the bank. Shareholders' equity totaled $207.4 million as of March 31, 2018, compared to $207.3 million at December 31, 2017 and $146.4 million at March 31, 2017. The increase from March 31, 2017 was primarily the result of operating earnings and the proceeds of the Company's initial public offering.

The company's Chairman and Chief Executive Officer, Ty Abston, said, "Guaranty achieved good net earnings growth in the first quarter, with a 24.0% increase over the first quarter of last year. Our loan growth was in-line with expectations and should accelerate further into the year. We are on pace to close the pending Westbound acquisition during the second quarter of 2018 and look forward to the opportunities that expansion brings to our franchise."

(1) In accordance with provisions of the Internal Revenue Code applicable to private companies, the terms of our KSOP required us, for a specified time, to repurchase shares of our common stock distributed to participants from the KSOP. Accordingly, the shares of our common stock held by the KSOP while we were a private company are reflected in our consolidated balance sheet as a line item between total liabilities and shareholders’ equity. Upon listing of our common stock on the NASDAQ Global Select Market in May 2017, this repurchase obligation terminated and, consequently, we were no longer required to deduct KSOP-owned shares from shareholders’ equity.

(2) See Reconciliation of non-GAAP Financial Measures table

(3) The efficiency ratio was calculated by dividing total noninterest expense by net interest income plus noninterest income, excluding securities gains or losses. Taxes are not part of this calculation.

About Non-GAAP Financial Measures

Certain of the financial measures and ratios we present, including “tangible book value per share” are supplemental measures that are not required by, or are not presented in accordance with, U.S. generally accepted accounting principles (GAAP). We refer to these financial measures and ratios as “non-GAAP financial measures.” We consider the use of select non-GAAP financial measures and ratios to be useful for financial and operational decision making and useful in evaluating period-to-period comparisons. We believe that these non-GAAP financial measures provide meaningful supplemental information regarding our performance by excluding certain expenditures or assets that we believe are not indicative of our primary business operating results or by presenting certain metrics on a fully taxable equivalent basis. We believe that management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, analyzing and comparing past, present and future periods.

These non-GAAP financial measures should not be considered a substitute for financial information presented in accordance with GAAP and you should not rely on non-GAAP financial measures alone as measures of our performance. The non-GAAP financial measures we present may differ from non-GAAP financial measures used by our peers or other companies. We compensate for these limitations by providing the equivalent GAAP measures whenever we present the non-GAAP financial measures and by including a reconciliation of the impact of the components adjusted for in the non-GAAP financial measure so that both measures and the individual components may be considered when analyzing our performance.

A reconciliation of non-GAAP financial measures to the comparable GAAP financial measures is included at the end of the financial statement tables.
