forward-looking statements within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. From time to
time, oral or written forward-looking statements may also be included in other information released to the public. Such statements are typically, but not exclusively, identified by the use in the statements of words or phrases such as
aim, anticipate, 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. These forward-looking statements may include information about
Prosperitys and LegacyTexass 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 Prosperitys or LegacyTexass future capital expenditures and dividends, future financial condition and changes therein, including changes in Prosperitys and LegacyTexass loan portfolio and allowance
for loan losses, future capital structure or changes therein, as well as the plans and objectives of management for Prosperitys or LegacyTexass future operations, future or proposed acquisitions, the future or expected effect of
acquisitions on Prosperitys or LegacyTexass 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. The forward-looking statements are based on expectations and assumptions Prosperity and LegacyTexas currently believe to be valid. Because forward-looking statements relate to future results and
occurrences, 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, LegacyTexas
or the combined company and could cause those results or performance to differ materially from those expressed in the forward-looking statements. Such risks and uncertainties include, among others: the occurrence of any event, change or other
circumstance that could give rise to the right of one or both of the parties to terminate the merger agreement, the outcome of any legal proceedings that may be instituted against Prosperity or LegacyTexas, delays in completing the transaction, the
failure to obtain necessary regulatory approvals (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the transaction) or shareholder approvals or
to satisfy any of the other conditions to the transaction on a timely basis or at all, the possibility that the anticipated benefits of the transaction are not realized when expected or at all, including as a result of the impact of, or problems
arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors generally, or specifically in the Dallas/Fort Worth area where LegacyTexas does a majority of its business and Prosperity has a
significant presence, the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events,
