Item 7.01 Regulation FD Disclosure.
On January 28, 2026, Stellar Bancorp, Inc., a Texas corporation (“Stellar”),
and Prosperity Bancshares, Inc., a Texas corporation (“Prosperity”), issued a joint press release announcing the execution
of an Agreement and Plan of Merger (the “Merger Agreement”), dated as of January 27, 2026, by and between Prosperity and Stellar,
pursuant to which, upon the terms and subject to the conditions set forth therein, Stellar will merge with and into Prosperity (the “Merger”),
with Prosperity continuing as the surviving corporation in the Merger. Immediately following the Merger, Stellar’s wholly owned
banking subsidiary, Stellar Bank, will merge with and into Prosperity’s wholly owned banking subsidiary, Prosperity Bank (the “Bank
Merger”), which will continue as the surviving bank in the Bank Merger. A copy of the joint press release is furnished as Exhibit
99.1 and incorporated by reference herein.
In connection with the announcement of the Merger Agreement, Prosperity
and Stellar intend to provide supplemental information regarding the proposed transaction in connection with presentations to analysts
and investors. The slides that will be available in connection with the presentations are attached hereto as Exhibit 99.2 and are incorporated
by reference herein.
The information in this Item 7.01, including Exhibit 99.1 and Exhibit
99.2, is furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended
(the “Exchange Act”), or otherwise subject to liabilities under that section, and shall not be deemed to be incorporated by
reference into the filings of Stellar under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange
Act, regardless of any general incorporation language in such filings.
Cautionary Notes on Forward Looking Statements
This Current Report on Form 8-K contains statements regarding the proposed
transaction between Prosperity and Stellar; future financial and operating results; benefits and synergies of the proposed transaction;
future opportunities for Prosperity; the issuance of common stock of Prosperity contemplated by the Merger Agreement; the expected filing
by Prosperity with the Securities and Exchange Commission (the “SEC”) of a registration statement on Form S-4 (the “Registration
Statement”) and a prospectus of Prosperity and a proxy statement of Stellar to be included therein (the “Proxy Statement/Prospectus”);
the expected timing of the closing of the proposed transaction; the ability of the parties to complete the proposed transaction considering
the various closing conditions and any other statements about future expectations that constitute forward-looking statements within the
meaning of the federal securities laws, including the meaning of the Private Securities Litigation Reform Act of 1995, as amended, Section
27A of the Securities Act, and Section 21E of the Exchange Act. From time to time, oral or written forward-looking statements may also
be included in other information released to the public. Such forward-looking statements are typically, but not exclusively, identified
by the use in the statements of words or phrases such as “aim,” “anticipate,” “believe,” “estimate,”
“expect,” “goal,” “guidance,” “intend,” “is anticipated,” “is expected,”
“is intended,” “objective,” “plan,” “projected,” “projection,” “will
affect,” “will be,” “will continue,” “will decrease,” “will grow,” “will impact,”
“will increase,” “will incur,” “will reduce,” “will remain,” “will result,”
“would be,” variations of such words or phrases (including where the word “could,” “may,” or “would”
is used rather than the word “will” in a phrase) and similar words and phrases indicating that the statement addresses some
future result, occurrence, plan or objective. Forward-looking statements include all statements other than statements of historical fact,
including forecasts or trends, and are based on current expectations, assumptions, estimates, and projections about Prosperity, Stellar
and their respective subsidiaries or related to the proposed transaction between Prosperity and Stellar and are subject to significant
risks and uncertainties that could cause actual results to differ materially from the results expressed in such statements.
These forward-looking statements may include information about Prosperity’s
and Stellar’s possible or assumed future economic performance or future results of operations, including future revenues, income,
expenses, provision for loan losses, provision for taxes, effective tax rate, earnings per share and cash flows and Prosperity’s
and Stellar’s future capital expenditures and dividends, future financial condition and changes therein, including changes in Prosperity’s
and Stellar’s loan portfolio and allowance for loan losses, future capital structure or changes therein, as well as the plans and
objectives of management for Prosperity’s and Stellar’s future operations, future or proposed acquisitions, the future or
expected effect of acquisitions on Prosperity’s and Stellar’s operations, results of operations, financial condition, and
future economic performance, statements about the anticipated benefits of the proposed transaction, and statements about the assumptions
underlying any such statement.
These forward-looking statements are not guarantees of future performance
and are based on expectations and assumptions Prosperity and Stellar currently believe to be valid. Because forward-looking statements
relate to future results and occurrences, many of which are outside of the control of Prosperity and Stellar, they are subject to inherent
uncertainties, risks and changes in circumstances that are difficult to predict. Many possible events or factors could adversely affect
the future financial results and performance of Prosperity, Stellar or the combined company and could cause those results or performance
to differ materially from those expressed in or implied by the forward-looking statements. Such risks and uncertainties include, among
others: (1) the risk that the cost savings and synergies from the proposed transaction may not be fully realized or may take longer than
anticipated to be realized, (2) disruption to Prosperity’s and Stellar’s businesses as a result of the announcements and pendency
of the proposed transaction, (3) the risk that the integration of Stellar’s businesses and operations into Prosperity will be materially
delayed or will be more costly or difficult than expected, or that Prosperity is otherwise unable to successfully integrate Stellar’s
business into its own, including as a result of unexpected factors or events, (4) the failure to obtain the necessary approval by the
shareholders of Stellar, (5) the ability by Prosperity and/or Stellar to obtain required governmental approvals of the proposed transaction
on the timeline expected, or at all, and the risk that such approvals may result in the imposition of conditions that could adversely
affect Prosperity after the closing of the proposed transaction or adversely affect the expected benefits of the proposed transaction,
(6) reputational risk and the reaction of each company’s customers, suppliers, employees or other business partners to the proposed
transaction, (7) the failure of the closing conditions in the Merger Agreement to be satisfied, or any unexpected delay in closing the
proposed transaction or the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger
Agreement, (8) the dilution caused by the issuances of additional shares of Prosperity’s common stock in the proposed transaction,
(9) the possibility that the proposed transaction may be more expensive to complete than anticipated, including as a result of unexpected
factors or events, (10) the outcome of any legal or regulatory proceedings that may be currently pending or later instituted against Prosperity
before or after the proposed transaction, or against Stellar, (11) diversion of management’s attention from ongoing business operations
and (12) general competitive, economic, political and market conditions and other factors that may affect future results of Prosperity
and Stellar. Prosperity and Stellar disclaim any obligation to update such factors or to publicly announce the results of any revisions
to any of the forward-looking statements included herein to reflect future events or developments. These and various other risks, uncertainties,
assumptions, and factors are discussed in the Annual Reports on Form 10-K for the year ended December 31, 2024, Quarterly Reports on Form
10-Q, and Current Reports on Form 8-K, filed by Prosperity or Stellar and in other filings made by Prosperity and Stellar with the SEC
from time to time.
