ALLEGIANCE BANCSHARES, INC. REPORTS

RECORD RESULTS FOR THE SECOND QUARTER 2021

HOUSTON, July 29, 2021 - Allegiance Bancshares, Inc. (NASDAQ: ABTX) (Allegiance), the holding company of Allegiance Bank (the "Bank"), today reported record net income of $22.9 million and diluted earnings per share of $1.12 for the second quarter 2021 compared to net income of $9.9 million and diluted earnings per share of $0.48 for the second quarter 2020. Net income for the six months ended June 30, 2021 was $40.9 million, or $2.01 per diluted share, compared to $13.4 million, or $0.65 per diluted share, for the six months ended June 30, 2020. The second quarter and six months ended June 30, 2021 results were primarily due to a recapture of provision for credit losses and increased net interest income driven by lower funding costs.

“We are excited to announce yet another record quarter for Allegiance, which came with core loan and deposit gains, and we enter the third quarter positioned for growth,” said Steve Retzloff, Allegiance’s Chief Executive Officer. “We maintained solid asset quality while economic factors improved which led us to a release of reserves for credit losses” commented Retzloff.

“The positive energy across Allegiance coupled with the outstanding determination of our employees continues to reinforce the execution of our business strategies with precision. The company-wide coordination of efforts has provided powerful momentum within our Treasury Management group as we continue to integrate new customers and focus on building both new and deepening existing customer relationships,” continued Retzloff.

“As we appreciate our successes in the first half of 2021, we believe we are in an excellent position of strength as we prepare for the remainder of the year. We have proven our ability to succeed in a highly competitive market and are well-positioned to support the growing needs of the communities we serve,” concluded Retzloff.

Second Quarter 2021 Results

Net interest income before the provision for credit losses in the second quarter 2021 increased $5.7 million, or 11.3%, to $56.6 million from $50.8 million for the second quarter 2020 and increased $898 thousand, or 1.6%, from $55.7 million in the first quarter 2021.  These increases were primarily due to changes in the volume and relative mix of the underlying assets and liabilities, the impact of loans within the Small Business Administration Paycheck Protection Program (PPP) under the Coronavirus Aid, Relief and Economic Security Act (CARES Act) as well as lower costs on interest-bearing liabilities.  The net interest margin on a tax equivalent basis decreased 8 basis points to 4.02% for the second quarter 2021 from 4.10% for the second quarter 2020 and decreased 17 basis points from 4.19% for the first quarter 2021. The decreases in the margin were primarily due to the decrease in the average yield on interest-earning assets partially offset by the decrease in funding costs.

Noninterest income for the second quarter 2021 was $2.3 million, an increase of $711 thousand, or 45.5%, compared to $1.6 million for the second quarter 2020 and increased $537 thousand, or 30.9%, compared to $1.7 million for the first quarter 2021.  Second quarter 2021 noninterest income reflected higher transactional fee income and no losses on sales of other real estate when compared to first quarter 2020.

Noninterest expense for the second quarter 2021 increased $3.8 million, or 12.8%, to $33.6 million from $29.8 million for the second quarter 2020 and decreased $1.3 million, or 3.8%, compared to the second quarter of 2020 and the first quarter 2021. The increase over the prior year was primarily due to increases in salaries and benefits and the reduced amount of deferred PPP loan origination costs compared to the second quarter of 2020.

In the second quarter 2021, Allegiance’s efficiency ratio increased to 57.07% compared to 56.92% for the second quarter 2020 and decreased from 60.85% for the first quarter 2021. Second quarter 2021 annualized returns on average assets, average equity and average tangible equity were 1.42%, 11.87% and 17.20%, respectively, compared to 0.71%, 5.51% and 8.32%, respectively, for the second quarter 2020.  Annualized returns on average assets, average equity and average tangible equity for the first quarter 2021 were 1.18%, 9.59% and 14.03%, respectively. Return on average tangible equity is a non-GAAP measure. Please refer to the non-GAAP reconciliation on page 11.  

Six Months Ended June 30, 2021 Results

Net interest income before provision for credit losses for the six months ended June 30, 2021 increased $16.4 million, or 17.1%, to $112.3 million from $95.9 million for the six months ended June 30, 2020 primarily due to a $880.6 million, or 18.7%, increase in average interest-earning assets over the prior year including the impact of PPP loans as well as lower costs related to interest-bearing liabilities. The net interest margin on a tax equivalent basis decreased 2 basis points to 4.10% for the six months ended June 30, 2021 from 4.12% for the six months ended June 30, 2020. The decrease in the margin over the prior year was primarily due to the decrease in the average yield on interest-earning assets partially offset by decreased funding costs.

Noninterest income for the six months ended June 30, 2021 was $4.0 million, a decrease of $278 thousand, or 6.5%, compared to $4.3 million for the six months ended June 30, 2020 due primarily to lower correspondent bank rebates and gains on the sale of securities.

Noninterest expense for the six months ended June 30, 2021 increased $6.3 million, or 10.2%, to $68.5 million from $62.2 million for the six months ended June 30, 2020.  The increase in noninterest expense over the six months ended June 30, 2020 was primarily due increased accruals for bonus and profit sharing due to increased net income along with the reduced amount of deferred PPP loan origination costs compared to the prior year.

Allegiance’s efficiency ratio decreased from 62.26% for the six months ended June 30, 2020 to 58.93% for the six months ended June 30, 2021. For the six months ended June 30, 2021, returns on average assets, average equity and average tangible equity were 1.30%, 10.75% and 15.65%, respectively, compared to 0.51%, 3.76% and 5.70%, respectively, for the six months ended June 30, 2020. Return on average tangible equity is a non-GAAP measure. Please refer to the non-GAAP reconciliation on page 11.
