HOUSTON, April 29, 2022 - Allegiance Bancshares, Inc. (NASDAQ: ABTX) (Allegiance), the holding company of Allegiance Bank (the "Bank"), today reported net income of $18.7 million and diluted earnings per share of $0.91 for the first quarter 2022 compared to net income of $18.0 million and diluted earnings per share of $0.89 for the first quarter 2021.

“We are delighted to report a productive start to 2022 driven by record core loan originations, with growth at an annualized rate of over 12% in the first quarter,” said Steve Retzloff, Allegiance’s Chief Executive Officer. “Our team’s outstanding efforts also delivered solid earnings results, credit quality metrics and deposit growth,” continued Retzloff.

“We are excited about the future of Allegiance and the pending merger of equals with CBTX, Inc. Our companies are embracing a unified approach as we collaborate to become the premier bank headquartered in the Houston region. We continue to remain true to delivering personalized and remarkable service to all of our customers. The effective combination of scale with our well-established relationship banking further strengthens our competitive position in a large and expanding market,” concluded Retzloff.

First Quarter 2022 Results

Net interest income before the provision for credit losses in the first quarter 2022 decreased $526 thousand, or 0.9%, to $55.2 million from $55.7 million for the first quarter 2021 and decreased $2.9 million, or 5.0%, from $58.1 million for the fourth quarter 2021. These decreases were primarily due to the changes in market interest rates and the decreased impact of loans within the Small Business Administration Paycheck Protection Program (PPP) partially offset by lower costs on interest-bearing liabilities. The net interest margin on a tax equivalent basis decreased 89 basis points to 3.30% for the first quarter 2022 from 4.19% for the first quarter 2021 and decreased 27 basis points from 3.57% for the fourth quarter 2021. The decreases in the margin were primarily due to the decrease in the average yield on interest-earning assets, driven by the increase in cash and securities, partially offset by the decrease in funding costs.

Noninterest income for the first quarter 2022 was $4.0 million, an increase of $2.3 million, or 131.5%, compared to $1.7 million for the first quarter 2021 and increased $1.6 million, or 63.7%, compared to $2.5 million for the fourth quarter 2021. First quarter 2022 other noninterest income included $1.3 million in income from Small Business Investment Company investments.

Noninterest expense for the first quarter 2022 decreased $402 thousand, or 1.2%, to $34.5 million from $34.9 million for the first quarter 2021 and decreased $2.2 million, or 6.1%, compared to the fourth quarter of 2021. The decrease over the fourth quarter 2021 was primarily due to decreased professional fees and acquisition and merger-related expenses associated with the pending merger with CBTX, Inc. partially offset by increased regulatory assessments and FDIC insurance.

In the first quarter 2022, Allegiance’s efficiency ratio decreased to 58.32% compared to 60.85% for the first quarter 2021 and 60.68% for the fourth quarter 2021. First quarter 2022 annualized returns on average assets, average equity and average tangible equity were 1.04%, 9.40% and 13.35%, respectively, compared to 1.18%, 9.59% and 14.03% for the first quarter 2021. Annualized returns on average assets, average

equity and average tangible equity for the fourth quarter 2021 were 1.23%, 10.60% and 15.05%, respectively. Return on average tangible equity is a non-GAAP measure. Please refer to the non-GAAP reconciliation on page 10.

Financial Condition

Total assets at March 31, 2022 increased $718.4 million, or 11.2%, to $7.15 billion compared to $6.43 billion at March 31, 2021 and increased $44.4 million, or 2.5% (annualized), compared to $7.10 billion at December 31, 2021, primarily due to the increased origination of core loans and growth in the securities portfolio partially offset by paydowns of PPP loans.

Total loans at March 31, 2022 decreased $375.7 million, or 8.1%, to $4.28 billion compared to $4.66 billion at March 31, 2021, primarily due to paydowns on PPP loans, and increased $63.0 million, or 6.0% (annualized) compared to $4.22 billion at December 31, 2021 due to the increase in organic core loans. Core loans, which exclude PPP loans, increased $274.1 million, or 7.0%, to $4.20 billion at March 31, 2022 from $3.93 billion at March 31, 2021 and increased $130.3 million, or 12.8% (annualized), from $4.07 billion at December 31, 2021.

Deposits at March 31, 2022 increased $788.1 million, or 14.7%, to $6.16 billion compared to $5.37 billion at March 31, 2021 and increased $114.7 million, or 7.6% (annualized), compared to $6.05 billion at December 31, 2021.

Asset Quality

Nonperforming assets totaled $26.3 million, or 0.37%, of total assets, at March 31, 2022 compared to $35.6 million, or 0.55%, of total assets, at March 31, 2021 and $24.1 million, or 0.34%, of total assets at December 31, 2021. The allowance for credit losses on loans as a percentage of total loans was 1.15% at March 31, 2022, 1.13% at March 31, 2021 and 1.14% at December 31, 2021.

The provision for credit losses for the first quarter 2022 was $1.8 million compared to $639 thousand for the first quarter 2021 and the recapture of provision for credit losses of $2.6 million for the fourth quarter 2021. The increase in the Company’s provision for credit losses in the first quarter of 2022 compared to the first and fourth quarters of 2021 reflects an increase in core loans.

First quarter 2022 net charge-offs were $317 thousand, or 0.03% (annualized) of average loans, a decrease from net charge-offs of $345 thousand, or 0.03% (annualized) of average loans, for the first quarter 2021 and a decrease of $1.0 million from $1.4 million, or 0.13% (annualized) of average loans, for the fourth quarter 2021.

Dividend

The Board of Directors of Allegiance declared a cash dividend on April 28, 2022 of $0.14 per share to be paid on June 15, 2022 to all shareholders of record as of May 31, 2022. The amount and timing of any future dividend payments to shareholders will be subject to the discretion of Allegiance’s Board of Directors.

Share Repurchase Authorization

On April 28, 2022, the Board of Directors of Allegiance authorized the repurchase of up to one million shares of outstanding Allegiance common stock through April 30, 2023. Repurchases under this program may be made from time to time through open market purchases, privately negotiated transactions or such other manners as will comply with applicable laws and regulations. The timing and actual number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements, market conditions and other corporate liquidity requirements and priorities. The repurchase program does not obligate Allegiance to purchase any particular number of shares and there is no guarantee as to the exact number of shares that will be repurchased by Allegiance. Allegiance may suspend, modify or terminate the program at any time and for any reason, without prior notice. On April 30, 2022, the Company’s previously approved one million share repurchase authorization will expire.

Pending Merger

On November 8, 2021, Allegiance and CBTX, Inc., jointly announced that they entered into a definitive merger agreement pursuant to which the companies will combine in an all-stock merger of equals. CBTX reported total assets of $4.49 billion as of December 31, 2021. Under the terms of the definitive merger agreement, Allegiance shareholders will receive 1.4184 shares of CBTX, Inc. common stock for each share of Allegiance common stock they own. Following the completion of the merger, we estimate that former Allegiance shareholders will own approximately 54% and former CBTX, Inc. shareholders will own approximately 46% of the combined company. The companies have submitted the required regulatory filings and, subject to satisfaction or in some cases waiver of the closing conditions, including approval of the merger agreement by both companies’ shareholders, the parties anticipate closing in the second quarter of the year. Each company has scheduled a special meeting for May 24, 2022 at which its respective shareholders will consider and vote on the merger agreement and other related matters.

GAAP Reconciliation and Management’s Explanation of Non-GAAP Financial Measures

(Unaudited)

Allegiance’s management uses certain non-GAAP (generally accepted accounting principles) financial measures to evaluate its performance. Allegiance believes that these non-GAAP financial measures provide meaningful supplemental information regarding its performance and that management and investors benefit from referring to these non-GAAP financial measures in assessing Allegiance’s performance and when planning, forecasting, analyzing and comparing past, present and future periods. Specifically, Allegiance reviews tangible book value per share, return on average tangible equity and the ratio of tangible equity to tangible assets for internal planning and forecasting purposes. Allegiance has included in this Earnings Release information relating to these non-GAAP financial measures for the applicable periods presented. These non-GAAP measures 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 Allegiance calculates the non-GAAP financial measures may differ from that of other companies reporting measures with similar names.
