STELLAR BANCORP, INC. REPORTS
FOURTH QUARTER 2022 RESULTS

HOUSTON, January 27, 2023 - Stellar Bancorp, Inc. (the “Company” or “Stellar”) (NASDAQ: STEL) today reported net income of $2.1 million, or $0.04 earnings per diluted share, for the fourth quarter 2022 and $51.4 million, or $1.47 earnings per diluted share, for the year ended December 31, 2022. The fourth quarter 2022 results for Stellar reflect the merger of equals (the “Merger”) between Allegiance Bancshares, Inc. (“Allegiance”) and CBTX, Inc. (“CBTX”), which became effective on October 1, 2022.
“We are pleased to report our fourth quarter results as a combined institution. Our scale and resources enhance our ability to execute our business strategy focused on delivering exceptional customer service to increase shareholder value while continuing to honor our community values. The integration of our combined talents and expertise benefits our customers, employees, communities and shareholders. We are very grateful for the dedication and hard work of our team coming together and for the continued work as we implement an efficient system conversion in the first quarter of 2023,” said Robert R. Franklin, Jr., Stellar’s Chief Executive Officer.

“As we approach 2023, we are excited about the opportunities created by our combination and also cautious about increasing interest rates and the resulting effects on our economy. We will focus our efforts in the coming year on credit quality, liquidity and capital management. We are convinced more than ever that there is a bright long-term future for Stellar,” concluded Mr. Franklin.

Fourth Quarter 2022 Financial Highlights
Total assets were $10.90 billion at year-end reflecting combined scale from the Merger.
Tax equivalent net interest margin was 4.71% for the fourth quarter 2022. The tax equivalent net interest margin, excluding purchase accounting accretion, was 4.38% for the fourth quarter. Refer to the calculation of this non-GAAP financial measure on page 11.
Net income for the fourth quarter 2022 of $2.1 million and diluted earnings per share of $0.04. Pre-tax, pre-provision income of $46.6 million and adjusted pre-tax, pre-provision income of $53.0 million for the fourth quarter 2022. Refer to the calculation of this non-GAAP financial measure on page 11.
As a result of the Merger, the Company recorded a $28.2 million provision for credit losses on non-purchased credit deteriorated (“non-PCD”) loans and a $5.0 million provision for unfunded commitments for the Current Expected Credit Loss requirement, along with a $7.6 million allowance for credit losses on purchase credit deteriorated (“PCD”) loans. Acquisition and merger related expenses totaled $11.5 million in the fourth quarter 2022.
Merger of Equals

On October 1, 2022, the Merger of Allegiance with CBTX was completed pursuant to an Agreement and Plan of Merger dated November 5, 2021 (as amended, the “Merger Agreement”), with the surviving corporation renamed Stellar Bancorp, Inc. Pursuant to the Merger Agreement, each share of Allegiance common stock was converted into the right to receive 1.4184 shares of common stock of the Company for each share of Allegiance common stock.

The Merger was accounted for as a reverse acquisition using the acquisition method of accounting, with CBTX treated as the legal acquirer and Allegiance treated as the accounting acquirer for financial reporting purposes. Therefore, the historical financial statements of the Company prior to the Merger reflect the historical financial statement balances of Allegiance. In addition, the assets and liabilities of CBTX as of the date of the Merger have been recorded at estimated fair value and added to those of Allegiance. The Company’s valuations of CBTX's assets and liabilities are preliminary and may be refined for up to a year from the date of the Merger. The Merger had a significant impact on all aspects of the Company's financial statements, and as a result, financial results after the Merger may not be comparable to financial results prior to the Merger. Results of operations reflect the combined operations following the Merger for the fourth quarter 2022 and stand-alone Allegiance for all periods prior.

Fourth Quarter 2022 Results
Stellar’s net interest income in the fourth quarter 2022 increased $57.5 million, or 99.0%, to $115.6 million from $58.1 million for the fourth quarter 2021 and increased $54.9 million, or 90.5%, from $60.7 million for the third quarter 2022. These increases were primarily due to the Merger. The net interest margin on a tax equivalent basis increased 114 basis points to 4.71% for the fourth quarter 2022 from 3.57% for the fourth quarter 2021 and increased 86 basis points from 3.85% for the third quarter 2022. The increase in the margin over the prior quarter and the comparable quarter in the prior year were primarily due to dynamics relating to the Merger and increases in interest rates. During the quarter, net interest income benefited from $8.2 million in income from purchase accounting adjustments. Excluding purchase accounting adjustments, net interest income would have been $107.5 million and the tax equivalent net interest margin would have been 4.38%.

Noninterest income for the fourth quarter 2022 was $10.6 million, an increase of $8.2 million, or 333.5%, compared to $2.5 million for the fourth quarter 2021 and an increase of $7.6 million, or 255.2%, compared to $3.0 million for the third quarter 2022. Noninterest income increased primarily due to nonrecurring gains on sale of securities, loans and assets held for sale totaling $4.0 million along with increased scale as a result of the Merger during the quarter.

Noninterest expense for the fourth quarter 2022 increased $42.9 million, or 116.7%, to $79.6 million from $36.7 million for the fourth quarter 2021 and increased $35.6 million, or 80.8%, compared to the third quarter of 2022. These increases in noninterest expense over the prior periods were primarily due to increases in operating expenses due to the Merger, most significantly salaries and benefits due to increased scale, and the amortization of core deposit intangibles. Acquisition and merger-related expenses associated with the Merger totaled $11.5 million during the quarter.
Stellar’s efficiency ratio increased to 65.14% for the fourth quarter 2022 compared to 60.68% for the fourth quarter 2021 and decreased from 69.18% for the third quarter 2022. Fourth quarter 2022 annualized returns on average assets, average equity and average tangible equity were 0.07%, 0.60% and 1.18%, respectively, compared to 1.23%, 10.60% and 15.05% for the fourth quarter 2021. Annualized returns on average assets, average equity and average tangible equity for the third quarter 2022 were 0.84%, 7.90% and 11.78%, respectively. Return on average tangible equity is a non-GAAP measure. Please refer to the non-GAAP reconciliation on page 11.  
Year Ended December 31, 2022 Results
Net interest income before provision for credit losses for the year ended December 31, 2022 increased $60.4 million, or 26.4%, to $289.0 million from $228.6 million for the year ended December 31, 2021 primarily due to the Merger. The net interest margin on a tax equivalent basis increased 4 basis points to 3.94% for the year ended December 31, 2022 from 3.90% for the year ended December 31, 2021. The increase in the margin over the prior year was primarily due to the increase in the average yield on interest-earning assets partially offset by increased funding costs. Excluding purchase accounting adjustments, net interest income would have been $280.6 million and the tax equivalent net interest margin would have been 3.83%.
Noninterest income for the year ended December 31, 2022 was $20.4 million, an increase of $11.8 million, or 137.7%, compared to $8.6 million for the year ended December 31, 2021 due primarily to the Merger and nonrecurring gains on sale of assets.
Noninterest expense for the year ended December 31, 2022 increased $56.5 million, or 40.5%, to $196.1 million from $139.6 million for the year ended December 31, 2021. The increase in noninterest expense over the year ended December 31, 2021 was primarily due to increased salaries and benefits, amortization of core deposit intangibles and acquisition and merger-related expenses associated with the Merger.
Stellar’s efficiency ratio increased to 64.23% for the year ended December 31, 2022 from 58.86% for the year ended December 31, 2021. For the year ended December 31, 2022, returns on average assets, average equity and average tangible equity were 0.64%, 5.69% and 9.16%, respectively, compared to 1.24%, 10.38% and 14.93%, respectively, for the year ended December 31, 2021.

Stellar Bancorp, Inc.
GAAP Reconciliation and Management’s Explanation of Non-GAAP Financial Measures
(Unaudited)
Stellar’s management uses certain non-GAAP (generally accepted accounting principles) financial measures to evaluate its performance. Stellar 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 Stellar’s performance and when planning, forecasting, analyzing and comparing past, present and future periods. Specifically, Stellar reviews pre-tax, pre-provision income, pre-tax pre-provision ROAA, adjusted pre-tax, pre-provision income, adjusted pre-tax, pre-provision ROAA, adjusted efficiency ratio, tangible book value per share, return on average tangible equity, tangible equity to tangible assets and net interest margin (tax equivalent) excluding PAA for internal planning and forecasting purposes. Stellar 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 Stellar calculates the non-GAAP financial measures may differ from that of other companies reporting measures with similar names.
