PRESS RELEASE

STELLAR BANCORP, INC. REPORTS

THIRD QUARTER 2025 RESULTS

HOUSTON, October 24, 2025 - Stellar Bancorp, Inc. (the “Company” or “Stellar”) (NYSE: STEL) today reported net income of $25.7 million, or diluted earnings per share of $0.50, for the third quarter of 2025, compared to net income of $26.4 million, or diluted earnings per share of $0.51, for the second quarter of 2025.

“We are pleased to report strong third quarter results for 2025, highlighted by improved net interest income and margin. We also saw growth in deposits and tangible book value, which further strengthened our balance sheet to support our future,” said Robert R. Franklin, Jr., Stellar’s Chief Executive Officer.

“Our team has continued to reposition the loan portfolio, reducing our exposure to non-relationship real estate commitments and moving toward a more balanced mix of C&I and real estate loans. Our real estate portfolio remains within regulatory guidance, and we intend to stay within those parameters. While loan payoffs persisted during the quarter, we believe this strategic portfolio shift will help moderate payoff activity over the longer term,” Mr. Franklin continued.

“Credit quality remains good, and the Texas markets we serve continue to perform well. Stellar is increasingly recognized as a strong, locally-managed bank focused on serving small-to-medium sized businesses, and we are well-positioned to capitalize on merger-related disruption in our markets. We remain confident in our ability to deepen customer relationships and deliver long-term value for our shareholders,” Mr. Franklin concluded.

Financial Highlights

•Strong Net Interest Margin: Tax equivalent net interest margin for the third quarter of 2025 was 4.20% compared to 4.18% for the second quarter of 2025. The tax equivalent net interest margin, excluding purchase accounting accretion (“PAA”), was 4.00%(1) for the third quarter of 2025 compared to 3.95%(1) for the second quarter of 2025.

•Solid Profitability: Net income for the third quarter of 2025 was $25.7 million, or diluted earnings per share of $0.50, which translated into an annualized return on average assets of 0.97%, an annualized return on average equity of 6.30% and an annualized return on average tangible equity of 11.45%(1).

•Strong Capital Position and Book Value Build: Total risk-based capital ratio increased to 16.33% at September 30, 2025 from 15.98% at June 30, 2025, while book value per share increased to $32.27 at September 30, 2025 from $31.20 at June 30, 2025 and tangible book value per share increased to $21.08(1) at September 30, 2025 from $19.94(1) at June 30, 2025.

•Paydown of Subordinated Debt: On October 1, 2025, the Company completed the previously announced redemption of $30 million of its $60 million of subordinated debt outstanding as of September 30, 2025.

Third Quarter 2025 Results

Net interest income in the third quarter of 2025 increased $2.3 million, or 2.3%, to $100.6 million from $98.3 million for the second quarter of 2025. The net interest margin on a tax equivalent basis increased to 4.20% for the third quarter of 2025 from 4.18% for the second quarter of 2025. The increase in net interest income from the prior quarter was primarily due to the increase in average securities, average yield on securities and deposits in other financial institutions. Net interest income for the third quarter of 2025 benefited from $4.8 million of income from PAA compared to $5.3 million in the second quarter of 2025. Excluding PAA, net interest income (tax equivalent) for the third quarter of 2025 would have been $95.9 million(1) and the tax equivalent net interest margin would have been 4.00%(1).

____________

(1)     Refer to the calculation of this non-GAAP financial measure on page 10 of this earnings release. The calculation of returns on average tangible equity and the efficiency ratio have been adjusted from prior period disclosures.

Noninterest income for the third quarter of 2025 was $5.0 million, a decrease of $805 thousand, or 13.9%, compared to $5.8 million for the second quarter of 2025. Noninterest income decreased in the third quarter of 2025 compared to the second quarter of 2025 primarily due to losses on sales and write-downs on foreclosed assets recorded during the third quarter.

Noninterest expense for the third quarter of 2025 increased $3.1 million, or 4.5%, to $73.1 million compared to $70.0 million for the second quarter of 2025. The increase in noninterest expense during the third quarter of 2025 compared to the second quarter of 2025 was primarily due to an increase in salaries and employee benefits of $2.2 million, an increase in professional fees of $314 thousand and a $258 thousand increase in advertising expense. Salaries and benefits during the third quarter of 2025 included $464 thousand in severance expense related to planned upcoming branch closures.

The efficiency ratio was 63.69%(1) for the third quarter of 2025 compared to 61.87%(1) for the second quarter of 2025. Annualized returns on average assets, average equity and average tangible equity were 0.97%, 6.30% and 11.45%(1) for the third quarter of 2025, respectively, compared to 1.01%, 6.62% and 12.16%(1) for the second quarter of 2025, respectively.

Financial Condition

Total assets at September 30, 2025 were $10.63 billion, an increase of $135 million compared to $10.49 billion at June 30, 2025. The increase in total assets was largely due to an increase in interest-bearing deposits at other financial institutions and securities, all of which were funded largely by core deposit growth, partially offset by a decrease in loans.

Total loans at September 30, 2025 decreased $119.5 million to $7.17 billion compared to $7.29 billion at June 30, 2025. At September 30, 2025, the remaining balance of the PAA on loans was $58.1 million.

Total deposits at September 30, 2025 increased $143.8 million to $8.82 billion compared to $8.67 billion at June 30, 2025 primarily due to increases in money market and savings deposits.

Asset Quality

Nonperforming assets totaled $54.2 million, or 0.51% of total assets, at September 30, 2025, compared to $58.2 million, or 0.55% of total assets, at June 30, 2025. The allowance for credit losses on loans as a percentage of total loans was 1.10% at September 30, 2025 compared to 1.14% at June 30, 2025.

The provision for credit losses was $305 thousand for the third quarter of 2025 compared to $1.1 million for the second quarter of 2025. Net charge-offs for the third quarter of 2025 were $3.3 million, or 0.18% (annualized) of average loans, compared to net charge-offs of $206 thousand, or 0.01% (annualized) of average loans, for the second quarter of 2025.

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, 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.

Forward-Looking Statements and Non-GAAP Financial Measures 2 Certain statements in this press release which are not historical in nature are intended to be, and are hereby identified as, “forward-looking statements” for purposes of the safe harbor provided by Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These statements include, but are not limited to, statements about future financial performance of Stellar Bancorp, Inc. (the “Company”), operating results, plans, business and growth strategies, objectives, expectations and intentions, and other statements that are not historical facts, including projections of macroeconomic and industry trends, which are inherently unreliable due to the multiple factors that impact economic trends, and any such variations may be material. Forward-looking statements may be identified by terminology such as “may,” “will,” “should,” “could,” “scheduled,” “plans,” “intends,” “projects,” “anticipates,” “expects,” “believes,” “estimates,” “potential,” “would,” or “continue” or negatives of such terms or other comparable terminology. All forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties and other factors that may cause the actual results, performance or achievements of the Company. Such factors include, among others: changes in the interest rate environment, the value of the Company’s assets and obligations and the availability of capital and liquidity; general competitive, economic, political and market conditions; and other factors that may affect future results of the Company including changes in asset quality and credit risk; the inability to sustain revenue and earnings growth; changes in interest rates and capital markets; inflation; customer borrowing, repayment, investment and deposit practices; the impact, extent and timing of technological changes; capital management activities; disruptions to the economy and the U.S. banking system; risks associated with uninsured deposits and responsive measures by federal or state governments or banking regulators; legislative changes, executive orders, regulatory actions and reforms of the Board of Governors of the Federal Reserve System, Federal Deposit Insurance Corporation and Texas Department of Banking. Additional factors which could affect the Company’s future results can be found in the Company’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, in each case filed with the SEC and available on the SEC’s website at www.sec.gov. We disclaim any obligation and do not intend to update or revise any forward-looking statements contained in this communication, which speak only as of the date hereof, whether as a result of new information, future events or otherwise, except as required by federal securities laws. As forward-looking statements involve significant risks and uncertainties, caution should be exercised against placing undue reliance on such statements. GAAP Reconciliation of Non-GAAP Financial Measures The Company’s management uses certain non-GAAP (generally accepted accounting principles) financial measures to evaluate its performance. The Company 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 the Company’s performance and when planning, forecasting, analyzing and comparing past, present and future periods. Specifically, the Company reviews pre-tax, pre-provision income, pre-tax pre-provision ROAA, 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. The Company 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 the Company calculates the non-GAAP financial measures may differ from that of other companies reporting measures with similar names.
