General

PART I

Prosperity Bancshares, Inc.®, a Texas corporation (the “Company”), was formed in 1983 as a vehicle to acquire
the former Allied Bank in Edna, Texas, which was chartered in 1949 as The First National Bank of Edna and is now
known as Prosperity Bank. The Company is a registered financial holding company that derives substantially all of its
revenues and income from the operation of its bank subsidiary, Prosperity Bank® (“Prosperity Bank®” or the “Bank”).
The Bank provides a wide array of financial products and services to businesses and consumers throughout Texas and
Oklahoma. As of December 31, 2023, the Bank operated 285 full service banking locations: 65 in the Houston area,
including The Woodlands; 30 in the South Texas area including Corpus Christi and Victoria; 62 in the Dallas/Fort
Worth area; 22 in the East Texas area; 32 in the Central Texas area including Austin and San Antonio; 44 in the West
Texas area including Lubbock, Midland-Odessa, Abilene; Amarillo and Wichita Falls; 16 in the Bryan/College Station
area, 6 in the Central Oklahoma area; and 8 in the Tulsa, Oklahoma area. The Company’s principal executive office
is located at Prosperity Bank Plaza, 4295 San Felipe in Houston, Texas and its telephone number is (281) 269-7199.
The Company’s website address is www.prosperitybankusa.com.

The Company’s market consists of the communities served by its banking centers. The diverse nature of the
economies in each local market served by the Company provides the Company with a varied customer base and allows
the Company to spread its lending risk throughout a number of different industries including professional service firms
and their principals, manufacturing, tourism, recreation, petrochemicals, farming and ranching. The Company’s
market areas outside of Houston, Dallas, Corpus Christi, San Antonio, Lubbock, Austin, Tulsa and Oklahoma City
are dominated by either small community banks or branches of larger regional banks. Management believes that the
Company,
through its responsive customer service and community banking philosophy, combined with the
sophistication of a larger regional bank holding company, has a competitive advantage in its market areas and excellent
growth opportunities through acquisitions, new banking center locations and additional business development.

Operating under a community banking philosophy, the Company seeks to develop broad customer relationships
based on service and convenience while maintaining its prudent approach to lending and sound asset quality. The
Company has grown through a combination of internal growth, merger and acquisition transactions and the opening
of new banking centers. As a result of its stable customer relationships, the Company is able to maintain a low cost of
funds. Utilizing that and employing stringent cost controls, the Company has been profitable in every year of its
existence, including the periods of adverse economic conditions in Texas and Oklahoma.

In addition to internal growth, the Company completed the following acquisitions within the last ten years

(through December 31, 2023):

Pending Acquisition of Lone Star State Bancshares, Inc. (“Lone Star”) — On October 11, 2022, the Company
and Lone Star jointly announced the signing of a definitive merger agreement whereby Lone Star, the parent company
of Lone Star State Bank of West Texas (“Lone Star Bank”), will merge with and into the Company. Lone Star Bank

specific industries found in the community. The Company operates each banking center as a separate profit center,
maintaining separate data with respect to each banking center’s net interest income, efficiency ratio, deposit growth,

Banking Activities

The Company, through the Bank, offers a variety of traditional loan and deposit products to its customers, which
consist primarily of individual consumers and businesses throughout Texas and Oklahoma. At December 31, 2023,
the Bank maintained approximately 813,000 separate deposit accounts including certificates of deposit and 72,500
separate loan accounts. At December 31, 2023, noninterest-bearing demand deposits were 36.0% of the Bank’s total
deposits. For the year ended December 31, 2023, the Company’s average cost of funds was 1.54% and the Company’s
average cost of deposits (excluding all borrowings) was 1.00%.

The Company has been an active real estate lender, with commercial real estate (including farmland and multi-
family residential), 1-4 family residential (including home equity) and construction, land development and other land
loans comprising 29.6%, 38.5% and 14.5%, respectively, of the Company’s total loans as of December 31, 2023. The
Company is active in commercial and industrial lending, with commercial loans comprising 10.9% of the Company’s
total loans as of December 31, 2023. The Company also offers agricultural loans, loans for automobiles and other
consumer durables, home equity loans, debit and credit cards, digital banking solutions, trust and wealth management,
retail brokerage services, mortgage services and treasury management. The Company offers businesses a broad array
of loan products including term loans, lines of credit and loans for working capital, business expansion and the
purchase of equipment and machinery; land development and interim construction loans for builders; and owner-
occupied and non-owner occupied commercial real estate loans. The Company has a Warehouse Purchase Program
that allows mortgage banking company customers to close one-to-four-family real estate loans in their own name and
manage their cash flow needs until the loans are sold to investors.

By offering certificates of deposit, interest checking accounts, money market accounts and savings accounts at

competitive rates, the Company gives its depositors a full range of traditional deposit products.

As of December 31, 2023, the Company’s trust department maintained total assets of $2.67 billion, including
managed assets of $2.26 billion. The trust department provides trust services in the Company’s various market areas.

Business Strategies

The Company’s main objective is to increase deposits and loans through internal growth, as well as through
acquisition opportunities, while maintaining efficiency, providing individualized customer service and maximizing
profitability. To achieve this objective, the Company has employed the following strategic goals:

Continue Community Banking Emphasis. Although the Company has significantly grown in the last several
years, it intends to continue operating as a community banking organization focused on meeting the specific needs of
consumers and businesses in its market areas. The Company provides a high degree of responsiveness combined with
a wide variety of banking products and services. The Company staffs its banking centers with experienced bankers
who possess lending expertise to effectively serve their community and gives them authority with centralized support
to make certain pricing and credit decisions, avoiding the bureaucratic structure of larger banks. Each banking center
has its own listed local business telephone number. Customers are served by a local banker with decision making
authority. The Company also maintains specialty commercial lending lines of business staffed by bankers with lending
expertise in the various business lines—commercial middle market, energy, mortgage warehouse and insurance
lending.

Expand Market Share Through Internal Growth and a Disciplined Acquisition Strategy. The Company intends
to continue seeking opportunities, both inside and outside its existing markets, to expand either by acquiring existing
banks or branches of banks or by establishing new banking centers. All of the Company’s acquisitions have been
accretive to earnings within 12 months after acquisition date and generally have supplied the Company with relatively
low-cost deposits which have been used to fund the Company’s lending and investing activities. However, future
acquisitions, if any, may not be accretive to earnings within any particular time period. Factors used by the Company

4

to evaluate expansion opportunities include (1) the similarity in management and operating philosophies, (2) whether
the acquisition will be accretive to earnings and enhance shareholder value, (3) whether the acquisition will
strategically expand the Company’s geographic footprint and (4) the opportunity to enhance the Company’s market
presence in existing market areas.

Increase Loan Volume and Diversify Loan Portfolio. While maintaining its prudent approach to lending, the
Company has emphasized both new and existing loan products, focusing on increasing its commercial real estate,
commercial and industrial, and residential real estate loan portfolios. Loans at December 31, 2023 were $21.18 billion
compared with $18.84 billion at December 31, 2022, an increase of $2.34 billion or 12.4%. Commercial and industrial
loans were $2.31 billion and represented 10.9% of the total loan portfolio as of December 31, 2023. Commercial real
estate loans (including multifamily residential and excluding farmland) were $5.66 billion and represented 26.8% of
the total portfolio as of December 31, 2023. One-to-four-family residential loans (excluding home equity) were $7.20
billion and represented 34.0% of the total loan portfolio as of December 31, 2023. Construction, land development
and other land loans were $3.08 billion and represented 14.5% of the total loan portfolio as of December 31, 2023.
Warehouse Purchase Program loans were $822.2 million and represented 3.9% of the total loan portfolio as of
December 31, 2023.

Maintain Sound Asset Quality. The Company continues to maintain the sound asset quality that has been
representative of its historical loan portfolio. As the Company continues to diversify and increase its lending activities
and acquire loans in acquisitions, it may face higher risks of nonpayment and increased risks in the event of prolonged
economic downturns. The Company intends to continue to employ the strict underwriting guidelines and
comprehensive loan review processes that have contributed to its low incidence of nonperforming assets and minimal
charge-offs in relation to its size. Nonperforming assets were 0.34% of total loans and other real estate at December 31,
2023. Excluding Warehouse Purchase Program loans, nonperforming assets were 0.36% of total loans and other real
estate at December 31, 2023. All Warehouse Purchase Program loans were performing loans at December 31, 2023.

Continue Focus on Efficiency. The Company plans to maintain its stringent cost control practices and policies.
The Company has invested significantly in the infrastructure required to centralize many of its critical operations, such
as data processing and loan and deposit processing. For its banking centers, which the Company operates as
independent profit centers, the Company supplies complete support in the areas of loan review, appraisals, loan and
deposit processing, internal audit, compliance and training. Management believes that this centralized infrastructure
can accommodate additional growth while enabling the Company to minimize operational costs through economies
of scale.

Enhance Cross-Selling. The Company uses incentives and friendly competition to encourage cross-selling
efforts and increase cross-selling results among its associates. Officers and associates have access to each customer’s
existing and related account relationships and are better able to inform customers of additional products when
customers visit or call the various banking centers or use their drive-in facilities. In addition, the Company includes
product information on its web page and in monthly statements and other mailings.

Competition

The banking business is highly competitive, and the profitability of the Company depends principally on its
ability to compete in its market areas. The Company competes with other commercial banks, savings banks, savings
and loan associations, credit unions, finance companies, mutual funds, insurance companies, brokerage and investment
banking firms, asset-based nonbank lenders, financial technology companies and certain other nonfinancial entities,
including retail stores that may maintain their own credit programs and certain governmental organizations that may
offer more favorable financing than the Company. Continued consolidation and rapid technological changes within
the financial services industry will likely change the nature and intensity of competition, but should also create
opportunities for the Company to demonstrate and leverage its competitive advantages. The Company believes it has
been able to compete effectively with other financial institutions by emphasizing customer service, technology and
responsive decision-making with respect to loans, by establishing long-term customer relationships and building
customer loyalty and by providing products and services designed to address the specific needs of its customers.

Supervision and Regulation

The supervision and regulation of bank holding companies and their subsidiaries is intended primarily for the
protection of depositors, the Deposit Insurance Fund (“DIF”) of the Federal Deposit Insurance Corporation (“FDIC”)
and the banking system as a whole, and not for the protection of the bank holding company’s shareholders or creditors.
The banking agencies have broad enforcement power over bank holding companies and banks including the power to
impose substantial fines and other penalties for violations of laws and regulations.

The following description summarizes some of the laws to which the Company and the Bank are subject.
References in this Annual Report on Form 10-K to applicable statutes and regulations are brief summaries thereof, do
not purport to be complete, and are qualified in their entirety by reference to such statutes and regulations.

The Company

The Company is a financial holding company pursuant to the Gramm-Leach-Bliley Act and a bank holding
company registered under the Bank Holding Company Act of 1956, as amended (“BHCA”). Accordingly, the
Company is subject to primary supervision, regulation and examination by the Board of Governors of the Federal
Reserve System (“Federal Reserve Board”). The Gramm-Leach-Bliley Act, the BHCA and other federal laws subject
financial and bank holding companies to particular restrictions on the types of activities in which they may engage,
and to a range of supervisory requirements and activities, including regulatory enforcement actions for violations of
laws and regulations. Further, as a public company, the Company also files reports with the U.S. Securities and
Exchange Commission (“SEC”) and is subject to its regulatory authority, including the disclosure and regulatory
requirements of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, with
respect to the Company’s securities, financial reporting and certain governance matters. Because the Company’s
securities are listed on the New York Stock Exchange (“NYSE”), the Company is subject to NYSE's rules for listed
companies, including rules relating to corporate governance.

Regulatory Restrictions on Dividends and Repurchases. The Company is regarded as a legal entity separate and
distinct from the Bank. The principal source of the Company’s revenues is dividends received from the Bank. As
described in more detail below, federal and state law places limitations on the amount that banks may pay in dividends,
which the Bank must adhere to when paying dividends to the Company. It is the policy of the Federal Reserve Board
that bank holding companies should pay cash dividends on common stock only out of income available over the past
year and only if the prospective rate of earnings retention is consistent with the organization’s expected capital needs
and financial condition. The Federal Reserve Board’s policy provides that bank holding companies should not
maintain a level of cash dividends that undermines the bank holding company’s ability to serve as a source of strength
to its banking subsidiaries. The Federal Reserve Board is authorized to limit or prohibit the payment of dividends if,
in the Federal Reserve Board’s opinion, the payment of dividends would constitute an unsafe or unsound practice in
light of a bank holding company’s financial condition. Federal Reserve Board policy also provides that a bank holding
company should inform the Federal Reserve Board reasonably in advance of declaring or paying a dividend that
exceeds earnings for the period for which the dividend is being paid or that could result in a material adverse change
to the bank holding company's capital structure.

In July 2019, the federal bank regulators adopted final rules that, among other things, eliminated the standalone
in the Basel III Capital Rules for any repurchase of common stock. In certain
prior approval requirement
circumstances, the Company’s repurchases of its common stock may be subject to a prior approval or notice
requirement under other regulations, policies or supervisory expectations of the Federal Reserve Board. Any
redemption or repurchase of preferred stock or subordinated debt remains subject to the prior approval of the Federal
Reserve Board.

In August 2022, the Inflation Reduction Act of 2022 (the “IRA”) was enacted. Among other things, the IRA
imposes a new 1% excise tax on the fair market value of stock repurchased after December 31, 2022 by publicly traded
U.S. corporations. With certain exceptions, the value of stock repurchased is determined net of stock issued in the
year, including shares issued pursuant to compensatory arrangements.

Source of Strength. Federal Reserve Board policy and federal law require a bank holding company to act as a
source of financial strength to each of its banking subsidiaries. Under this requirement, the Company is expected to
commit resources to support the Bank, including support at times when the Company may not be in a financial position
to provide such resources. Any capital loans by a bank holding company to any of its subsidiary banks are subordinate
in right of payment to deposits and to certain other indebtedness of such subsidiary banks. As discussed below, a bank
holding company, in certain circumstances, could be required to guarantee the capital plan of an undercapitalized
banking subsidiary.

In the event of a bank holding company’s bankruptcy under Chapter 11 of the U.S. Bankruptcy Code, the trustee
will be deemed to have assumed and is required to cure immediately any deficit under any commitment by the debtor
holding company to any of the federal banking agencies to maintain the capital of an insured depository institution.
Any claim for breach of such obligation will generally have priority over most other unsecured claims.

Scope of Permissible Activities. Under the BHCA, bank holding companies generally may not acquire a direct
or indirect interest in or control of more than 5% of the voting shares of any company that is not a bank or bank holding
company and may not engage in activities other than those of banking, managing or controlling banks or furnishing
services to or performing services for its subsidiaries, except that it may engage in, directly or indirectly, certain
activities that the Federal Reserve Board has determined to be so closely related to banking or managing and
controlling banks as to be a proper incident thereto. In approving acquisitions or the addition of activities, the Federal
Reserve Board considers, among other things, whether the acquisition or the additional activities can reasonably be
expected to produce benefits to the public, such as greater convenience, increased competition, or gains in efficiency,
that outweigh such possible adverse effects as undue concentration of resources, decreased or unfair competition,
conflicts of interest or unsound banking practices.

Notwithstanding the foregoing, the Gramm-Leach-Bliley Act eliminated the barriers to affiliations among
banks, securities firms, insurance companies and other financial service providers and permits bank holding companies
to become financial holding companies and thereby affiliate with securities firms and insurance companies and engage
in other activities that are financial in nature. The Gramm-Leach-Bliley Act defines “financial in nature” to include
securities underwriting, dealing and market making; sponsoring mutual funds and investment companies; insurance
underwriting and agency; merchant banking activities; and activities that the Federal Reserve Board has determined
to be closely related to banking. Generally, no regulatory approval will be required for a financial holding company,
such as the Company, to acquire a company, other than a bank or savings association, engaged in activities that are
financial in nature or incidental to activities that are financial in nature as determined by the Federal Reserve Board.

The Company’s financial holding company status depends upon it maintaining its status as “well capitalized”
and “well managed” under applicable Federal Reserve Board regulations. If a financial holding company ceases to
meet these requirements, the Federal Reserve Board may impose corrective capital and/or managerial requirements
on the financial holding company and place limitations on its ability to conduct the broader financial activities
permissible for financial holding companies. Until the financial holding company returns to compliance, it may not
acquire a company engaged in such financial activities without prior approval of the Federal Reserve Board. In
addition, the Federal Reserve Board may require divestiture of the holding company’s depository institutions and/or
its non-bank subsidiaries if the deficiencies persist.

While the Federal Reserve Board is the “umbrella” regulator for financial holding companies and has the power
to examine banking organizations engaged in new activities, regulation and supervision of activities which are
financial in nature or determined to be incidental to such financial activities will be handled along functional lines.
Accordingly, activities of subsidiaries of a financial holding company will be regulated by the agency or authorities
with the most experience regulating that activity as it is conducted in a financial holding company.

Safe and Sound Banking Practices. Bank holding companies are not permitted to engage in unsafe and unsound
banking practices. The Federal Reserve Board’s Regulation Y, for example, generally requires a holding company to
give the Federal Reserve Board prior notice of any redemption or repurchase of its own equity securities if the
consideration to be paid, together with the consideration paid for any repurchases or redemptions in the preceding
year, is equal to 10% or more of the company’s consolidated net worth. The Federal Reserve Board may oppose the
transaction if it believes that the transaction would constitute an unsafe or unsound practice or would violate any law

7

or regulation. Depending upon the circumstances, the Federal Reserve Board could take the position that paying a
dividend would constitute an unsafe or unsound banking practice.

The Federal Reserve Board has broad authority to prohibit activities of bank holding companies and their
nonbanking subsidiaries which represent unsafe and unsound banking practices or which constitute violations of laws
or regulations, and can assess civil money penalties for certain activities conducted on a knowing and reckless basis
if those activities caused a substantial loss to a depository institution. The penalties can be in excess of $1.0 million
for each day the activity continues.

Anti-Tying Restrictions. Bank holding companies and their affiliates are prohibited from tying the provision of

certain services, such as extensions of credit, to other services offered by a holding company or its affiliates.

Basel III Capital Adequacy Requirements. The Company and the Bank are required to comply with applicable
capital adequacy standards adopted by the Federal Reserve Board and the FDIC (the “Basel III Capital Rules”). The
Basel III Capital Rules define the components of capital and address other issues affecting the numerator in banking
institutions’ regulatory capital ratio calculations and also address risk weights and other issues affecting the
denominator.

The Basel III Capital Rules require the Company to maintain a capital conservation buffer of Common Equity
Tier 1 (“CET1”) of 2.5%, effectively resulting in minimum ratios of (1) CET1 to risk-weighted assets of 7.0%, (2)
Tier 1 capital to risk-weighted assets of 8.5%, (3) total capital (that is, Tier 1 plus Tier 2) to risk-weighted assets of
10.5% and (4) Tier 1 capital to average quarterly assets as reported on consolidated financial statements (known as
the “leverage ratio”) of 4.0%. As of December 31, 2023, the Company’s ratio of CET1 to risk-weighted assets was
15.54%, Tier 1 capital to risk-weighted assets was 15.54%, total capital to risk-weighted assets was 16.56% and Tier
1 capital to average quarterly assets was 10.39%.

Banking institutions that fail to meet the effective minimum ratios once the capital conservation buffer is taken
into account, as detailed above, will be subject to constraints on capital distributions, including dividends and share
repurchases, and certain discretionary executive compensation. The severity of the constraints depends on the amount
of the shortfall and the institution’s “eligible retained income” (that is, four quarter trailing net income, net of
distributions and tax effects not reflected in net income).

With respect to the Bank, the Basel III Capital Rules also revised the “prompt corrective action” regulations as

discussed below under “The Bank—Corrective Measures for Capital Deficiencies.”

In response to the novel strain of coronavirus disease (“COVID-19”) pandemic, in March 2020 the joint federal
bank regulatory agencies issued an interim final rule that allowed banking organizations that implemented ASU 2016-
13, “Financial Instruments-Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments”
(“CECL”) in 2020 to mitigate the effects of the CECL accounting standard in their regulatory capital for two years.
This two-year delay is in addition to the three-year transition period that the agencies had already made available. The
Company adopted the option provided by the interim final rule, which delayed the effects of CECL on its regulatory
capital through 2021, after which the effects will be phased in over a three-year period from January 1, 2022 through
December 31, 2024. Under the interim final rule, the amount of adjustments to regulatory capital deferred until the
phase-in period include both the initial impact of the Company’s adoption of CECL on January 1, 2020 and 25% of
subsequent changes in the Company’s allowance for credit losses during each quarter of the two-year period ending
December 31, 2021. The cumulative amount of the transition adjustments is being phased in over the three-year
transition period that began on January 1, 2022, with 75% recognized in 2022, 50% recognized in 2023, and 25%
recognized in 2024.

The Basel III Capital Rules prescribe a standardized approach for risk weightings that expands the risk-
weighting categories from the general risk-based capital rules to a larger and more risk-sensitive number of categories,
depending on the nature of the assets, generally ranging from 0% for U.S. government and agency securities, to 600%
for certain equity exposures, and resulting in higher risk weights for a variety of asset categories.

8

In July 2023, the federal banking regulators proposed revisions to the Basel III capital rules to implement the
Basel Committee’s 2017 standards and make other changes to the Basel III capital rules. The proposal introduces
revised credit risk, equity risk, operational risk, credit evaluation risk, and market risk requirements, among other
changes. However, the revised capital requirements of the proposed rule would not apply to the Company or the Bank
because they each have less than $100 billion in total consolidated assets and trading assets and liabilities below the
threshold for the market risk requirements.

The federal banking agencies’ risk-based and leverage capital ratios are minimum supervisory ratios generally
applicable to banking organizations that meet certain specified criteria. Banking organizations not meeting these
criteria are expected to operate with capital positions well above the minimum ratios. The federal bank regulatory
agencies may set capital requirements for a particular banking organization that are higher than the minimum ratios
when circumstances warrant. Federal Reserve Board guidelines also provide that banking organizations experiencing
internal growth or making acquisitions will be expected to maintain strong capital positions substantially above the
minimum supervisory levels, without significant reliance on intangible assets.

Liquidity Requirements. The Basel III liquidity framework requires some banks and bank holding companies
to measure their liquidity against specific liquidity tests. One test, referred to as the liquidity coverage ratio (“LCR”),
is designed to ensure that a banking entity maintains an adequate level of unencumbered high-quality liquid assets
equal to the entity’s expected net cash outflow for a 30-day time horizon (or, if greater, 25% of its expected total cash
outflow) under an acute liquidity stress scenario. The other test, referred to as the net stable funding ratio (“NSFR”),
is designed to promote more medium- and long-term funding of the assets and activities of banking entities over a
one-year time horizon. Neither the LCR rule nor the NSFR rule apply to the Company and the Bank.

Imposition of Liability for Undercapitalized Subsidiaries. Bank regulators are required to take “prompt
corrective action” to resolve problems associated with insured depository institutions whose capital declines below
certain levels. If an institution becomes “undercapitalized,” it must submit a capital restoration plan. The capital
restoration plan will not be accepted by the regulators unless each company having control of the undercapitalized
institution guarantees the subsidiary’s compliance with the capital restoration plan up to a certain specified amount.
Any such guarantee from a depository institution’s holding company is entitled to a priority of payment in bankruptcy.

The aggregate liability of the holding company of an undercapitalized bank is limited to the lesser of 5% of the
institution’s assets at the time it became undercapitalized or the amount necessary to cause the institution to be
“adequately capitalized.” The bank regulators have greater power in situations where an institution becomes
“significantly” or “critically” undercapitalized or fails to submit a capital restoration plan. For example, a bank holding
company controlling such an institution can be required to obtain prior Federal Reserve Board approval of proposed
dividends or might be required to consent to a consolidation or to divest the troubled institution or other affiliates.

Acquisitions by Bank Holding Companies. The BHCA requires every bank holding company to obtain the prior
approval of the Federal Reserve Board before it may acquire all or substantially all of the assets of any bank, or
ownership or control of any voting shares of any bank, if after such acquisition it would own or control, directly or
indirectly, 5% or more of the voting shares of such bank. In approving bank acquisitions by bank holding companies,
the Federal Reserve Board is required to consider, among other things, the financial and managerial resources and
future prospects of the bank holding company and the banks concerned, the convenience and needs of the communities
to be served and various competitive factors.

Control Acquisitions. The Change in Bank Control Act prohibits a person or group of persons from acquiring
“control” of a bank holding company unless the Federal Reserve Board has been notified and has not objected to the
transaction. Under a rebuttable presumption established by the Federal Reserve Board, the acquisition of 10% or more
of a class of voting stock of a bank holding company with a class of securities registered under Section 12 of the
Exchange Act, such as the Company, would, under the circumstances set forth in the presumption, constitute
acquisition of control of the Company. In addition, a person may not acquire 25% (5% in the case of an acquiror that
is a bank holding company) or more of a bank holding company’s or bank’s voting securities, or otherwise obtain
control or a controlling influence over a bank holding company or bank without the approval of the Federal Reserve
Board.

9

In January 2020, the Federal Reserve Board approved a final rule that clarifies the framework for when a
company controls a bank holding company or bank under the BHCA. In particular, the final rule sets forth tiered
presumptions of control in the Federal Reserve Board’s regulations. Under the BHCA, a company controls a bank
holding company if it controls 25 percent or more of any class of voting securities of the bank holding company. A
company that controls less than 5 percent of any class of voting securities of a bank holding company is presumed not
to control the bank holding company. In instances in which a company owns at least 5 percent but less than 25 percent,
the Federal Reserve Board considers the full facts and circumstances of the relationship between the company and the
bank holding company to determine whether the company controls the bank holding company. As part of its
determination as to control, the Federal Reserve Board considers, among other things, level of ownership of voting
and non-voting securities, board representation, business relationships, senior management interlocks, contractual
limits on major operational or policy decisions, proxies on issues, threats to dispose of securities, and management
agreements. The rule also provides several additional examples of presumptions of control and noncontrol, along with
various ancillary provisions such as definitions of terms used in the presumptions.

The Volcker Rule. The Volcker Rule under the Dodd-Frank Wall Street Reform and Consumer Protection Act
("Dodd-Frank Act") prohibits banks and their affiliates from engaging in proprietary trading and investing in and
sponsoring certain hedge funds and private equity funds. Since neither the Company nor the Bank engages in the types
of trading or investing covered by the Volcker Rule, the Volcker Rule does not currently have any effect on the
operations of the Company or the Bank.

The Bank

The Bank is a Texas-chartered banking association, the deposits of which are insured by the DIF of the FDIC.
The Bank is not a member of the Federal Reserve System; therefore, the Bank is subject to supervision and regulation
by the FDIC and the Texas Department of Banking. Such supervision and regulation subject the Bank to special
restrictions, requirements, potential enforcement actions and periodic examination by the FDIC and the Texas
Department of Banking. Because the Federal Reserve Board regulates the Company, the Federal Reserve Board also
has supervisory authority which affects the Bank. Further, because the Bank has total assets of over $10 billion, the
Bank is also subject to supervision and regulation by the Consumer Financial Protection Bureau (“CFPB”). The CFPB
regulates the offering and provision of consumer financial products and services under the federal consumer financial
laws.

Equivalence to National Bank Powers. The Texas Constitution, as amended in 1986, provides that a Texas-
chartered bank has the same rights and privileges that are or may be granted to national banks domiciled in Texas. To
the extent that the Texas laws and regulations may have allowed state-chartered banks to engage in a broader range
of activities than national banks, the Federal Deposit Insurance Corporation Improvement Act of 1991 (“FDICIA”)
has operated to limit this authority. FDICIA provides that no state bank or subsidiary thereof may engage as principal
in any activity not permitted for national banks, unless the institution complies with applicable capital requirements
and the FDIC determines that the activity poses no significant risk to the DIF. In general, statutory restrictions on the
activities of banks are aimed at protecting the safety and soundness of depository institutions.

Financial Modernization. Under the Gramm-Leach-Bliley Act, a national bank may establish a financial
subsidiary and engage, subject to limitations on investment, in activities that are financial in nature other than
insurance underwriting as principal, insurance company portfolio investment, real estate development, real estate
investment, annuity issuance and merchant banking activities. To do so, a bank must be well capitalized, well managed
and have a CRA rating of satisfactory or better. Subsidiary banks of a financial holding company or national banks
with financial subsidiaries must remain well capitalized and well managed in order to continue to engage in activities
that are financial in nature without regulatory actions or restrictions, which could include divestiture of the financial-
in-nature subsidiary or subsidiaries. In addition, a financial holding company or a bank may not acquire a company
that is engaged in activities that are financial in nature unless each of the subsidiary banks of the financial holding
company or the bank has a CRA rating of satisfactory or better.

Although the powers of state chartered banks are not specifically addressed in the Gramm-Leach-Bliley Act,
Texas-chartered banks such as the Bank, will have the same if not greater powers as national banks through the parity
provision contained in the Texas Constitution.

10

Branching. Pursuant to the Dodd-Frank Act, banks are permitted to engage in de novo interstate branching if
the laws of the state where the new branch is to be established would permit the establishment of the branch if it were
chartered by such state, subject to applicable regulatory review and approval requirements. The Dodd-Frank Act also
modified certain regulatory requirements for interstate mergers and acquisitions, including that the acquiring bank
must be well capitalized and well managed. Texas law provides that a Texas-chartered bank can establish a branch
anywhere in Texas or any other state, subject to federal law requirements, provided that the branch is approved in
advance by the Texas Department of Banking. The branch must also be approved by the FDIC, which considers a
number of factors, including financial history, capital adequacy, earnings prospects, character of management, needs
of the community and consistency with corporate powers.

Restrictions on Transactions with Affiliates and Insiders. Transactions between the Bank and its nonbanking
affiliates, including the Company, are subject to Section 23A and Section 23B of the Federal Reserve Act. In general,
Section 23A imposes limits on the amount of such transactions to 10% of the Bank’s capital stock and surplus and
requires that such transactions be secured by designated amounts of specified collateral. It also limits the amount of
advances to third parties which are collateralized by the securities or obligations of the Company or its subsidiaries.
Section 23B generally requires that certain transactions between the Bank and its affiliates be on terms substantially
the same, or at least as favorable to the Bank, as those prevailing at the time for comparable transactions with or
involving other nonaffiliated persons.

Loans to directors, executive officers, principal shareholders and their related interests (collectively referred to
herein as “insiders”) are subject to restrictions contained in the Federal Reserve Act and Regulation O, which apply
to all insured institutions and their subsidiaries and holding companies. Insiders are subject to enforcement actions for
knowingly accepting loans in violation of applicable restrictions.

Restrictions on Distribution of Subsidiary Bank Dividends and Assets. Dividends paid by the Bank have
provided a substantial part of the Company’s operating funds, and it is anticipated that dividends paid by the Bank to
the Company will continue to be the Company’s principal source of operating funds. Capital adequacy requirements
serve to limit the amount of dividends that may be paid by the Bank. Under federal law, the Bank cannot pay a dividend
if, after paying the dividend, the Bank will be “undercapitalized.” The FDIC may declare a dividend payment to be
unsafe and unsound even though the Bank would continue to meet its capital requirements after the dividend. The
Bank is also subject to limitations on the payment of dividends under Texas law. Because the Company is a legal
entity separate and distinct from its subsidiaries, its right to participate in the distribution of assets of any subsidiary
upon the subsidiary’s liquidation or reorganization will be subject to the prior claims of the subsidiary’s creditors. In
the event of a liquidation or other resolution of an insured depository institution, the claims of depositors and other
general or subordinated creditors are entitled to a priority of payment over the claims of holders of any obligation of
the institution to its shareholders, including any depository institution holding company (such as the Company) or any
shareholder or creditor thereof.

Consumer Financial Protection. The Bank is subject to a number of federal and state consumer protection laws
that extensively govern its relationship with its customers. These laws include the Equal Credit Opportunity Act, the
Fair Credit Reporting Act, the Truth in Lending Act, the Truth in Savings Act, the Electronic Fund Transfer Act, the
Expedited Funds Availability Act, the Home Mortgage Disclosure Act, the Fair Housing Act, the Real Estate
Settlement Procedures Act, the Fair Debt Collection Practices Act, the Service Members Civil Relief Act and these
laws’ respective state-law counterparts, as well as state usury laws and laws regarding unfair and deceptive acts and
practices. These and other federal laws, among other things, require disclosures of the cost of credit and terms of
deposit accounts, provide substantive consumer rights, prohibit discrimination in credit transactions, regulate the use
of credit report information, provide financial privacy protections, prohibit unfair, deceptive and abusive practices,
restrict the Bank’s ability to raise interest rates and subject the Bank to substantial regulatory oversight. Violations of
applicable consumer protection laws can result in significant potential liability from litigation brought by customers,
including actual damages, restitution and attorneys’ fees. Federal bank regulators, state attorneys general and state and
local consumer protection agencies may also seek to enforce consumer protection requirements and obtain these and
other remedies, including regulatory sanctions, customer rescission rights and civil money penalties in each
jurisdiction in which the Bank operates. Failure to comply with consumer protection requirements may also result in
the Bank’s failure to obtain any required regulatory approval for merger or other acquisition transactions the Bank
may wish to pursue or its prohibition from engaging in such transactions even if approval is not required.

11

The Dodd-Frank Act established the CFPB, which has supervisory, examination and enforcement authority over
depository institutions with total assets of $10 billion or greater and other providers of consumer financial products or
services. The CFPB has broad rulemaking authority for a wide range of federal consumer financial laws, including,
among other things, the authority to prohibit “unfair, deceptive or abusive” acts and practices. The CFPB can issue
cease-and-desist orders against banks and other entities that violate federal consumer financial laws and may also
institute a civil action against an entity in violation of federal consumer financial laws in order to impose a civil penalty
or injunction.

In October 2023, the CFPB proposed a new rule that would require a provider of payment accounts or products,
such as a bank, to make data available to consumers upon request regarding the products or services they obtain from
the provider. Any such data provider would also have to make such data available to third parties, with the consumer’s
express authorization and through an interface that satisfies formatting, performance and security standards, for the
purpose of such third parties providing the consumer with financial products or services requested by the consumer.
Data that would be required to be made available under the rule would include transaction information, account
balance, account and routing numbers, terms and conditions, upcoming bill information, and certain account
verification data. The proposed rule is intended to give consumers control over their financial data, including with
whom it is shared, and encourage competition in the provision of consumer financial products or services. For banks
with over $50 billion and less than $500 billion in total assets, compliance would be required approximately one year
after adoption of the final rule.

Customer Information Security. The federal banking agencies have adopted guidelines for safeguarding
confidential, personal, nonpublic customer information. These guidelines require each financial institution, under the
supervision and ongoing oversight of its board of directors or an appropriate committee thereof, to create, implement
and maintain a comprehensive written information security program designed to ensure the security and confidentiality
of customer information, protect against any anticipated threats or hazard to the security or integrity of such
information and protect against unauthorized access to or use of such information that could result in substantial harm
or inconvenience to any customer. The Bank has adopted a customer information security program to comply with
these requirements.

Examinations. The FDIC periodically examines and evaluates state non-member banks, such as the Bank. The
Texas Department of Banking also conducts examinations of Texas-chartered banks, but may accept the results of a
federal examination in lieu of conducting an independent examination. Additionally, the FDIC and Texas Department
of Banking may elect to conduct a joint examination. Because the Bank has total assets of over $10 billion, the CFPB
also has examination authority with respect to the Bank’s compliance with federal consumer protection laws.

Capital Adequacy Requirements. The FDIC has adopted regulations establishing minimum requirements for the
capital adequacy of insured institutions. The FDIC may establish higher minimum requirements if, for example, a
bank has previously received special attention or has a high susceptibility to interest rate risk.

The FDIC’s risk-based capital guidelines generally require state banks to have minimum ratios of CET1 to risk-
weighted assets of 4.5%, Tier 1 capital to total risk-weighted assets of 6.0% and total capital to total risk-weighted
assets of 8.0%. The capital categories have the same definitions for the Bank as for the Company. As of December 31,
2023, the Bank’s ratio of CET1 to risk-weighted assets was 15.48%, Tier 1 capital to total risk-weighted assets was
15.48% and total capital to total risk-weighted assets was 16.50%.

The FDIC’s leverage guidelines require state banks to maintain Tier 1 capital of no less than 4.0% of average
total assets. As of December 31, 2023, the Bank’s ratio of Tier 1 capital to average quarterly assets (leverage ratio)
was 10.35%.

Corrective Measures for Capital Deficiencies. The federal banking regulators are required to take “prompt
corrective action” with respect to capital-deficient institutions. Agency regulations define, for each capital category,
the levels at which institutions are “well-capitalized,” “adequately capitalized,” “undercapitalized,” “significantly
undercapitalized” and “critically undercapitalized.”

•

A bank is “well capitalized” if it has a total risk-based capital ratio of 10.0% or higher; a CET1 capital
ratio of 6.5% or higher; a Tier 1 risk-based capital ratio of 8.0% or higher; a leverage ratio of 5.0% or

12

higher; and is not subject to any written agreement, order or directive requiring it to maintain a specific
capital level for any capital measure.

A bank is “adequately capitalized” if it has a total risk-based capital ratio of 8.0% or higher; a CET1
capital ratio of 4.5% or higher; a Tier 1 risk-based capital ratio of 6.0% or higher; a leverage ratio of 4.0%
or higher; and does not meet the criteria for a well capitalized bank.

A bank is “undercapitalized” if it has a total risk-based capital ratio of less than 8.0%; a CET1 capital
ratio less than 4.5%; a Tier 1 risk-based capital ratio of less than 6.0% or a leverage ratio of less than
4.0%.

A bank is “significantly undercapitalized” if it has a total risk-based capital ratio of less than 6.0%; a
CET1 capital ratio less than 3.0%; a Tier 1 risk-based capital ratio of less than 4.0% or a leverage ratio of
less than 3.0%.

A bank is “critically undercapitalized” if it has a tangible equity ratio to total assets that is equal to or less
than 2.0%.

•

•

•

•

At December 31, 2023, the Bank was classified as “well-capitalized” for purposes of the FDIC’s prompt

corrective action regulations in effect as of such date.

In addition to requiring undercapitalized institutions to submit a capital restoration plan, agency regulations
contain broad restrictions on certain activities of undercapitalized institutions including asset growth, acquisitions,
branch establishment and expansion into new lines of business. With certain exceptions, an insured depository
institution is prohibited from making capital distributions, including dividends, and is prohibited from paying
management fees to control persons if the institution would be undercapitalized after any such distribution or payment.

As an institution’s capital decreases, the FDIC’s enforcement powers become more severe. A significantly
undercapitalized institution is subject to mandated capital raising activities, restrictions on interest rates paid and
transactions with affiliates, removal of management and other restrictions. The FDIC has only very limited discretion
in dealing with a critically undercapitalized institution and is virtually required to appoint a receiver or conservator.

Banks with risk-based capital and leverage ratios below the required minimums may also be subject to certain
administrative actions, including the termination of deposit insurance upon notice and hearing, or a temporary
suspension of insurance without a hearing if the institution has no tangible capital.

In addition, the Federal Deposit Insurance Act prohibits an insured depository institution from accepting
brokered deposits or offering interest rates on any deposits significantly higher than the prevailing rate in the bank’s
normal market area or nationally (depending upon where the deposits are solicited), unless it is well capitalized or is
adequately capitalized and receives a waiver from the FDIC.

Deposit Insurance Assessments. The deposits of the Bank are insured up to applicable limits by the DIF, and
the Bank must pay deposit insurance assessments to the FDIC for such deposit insurance protection. A depository
institution’s DIF assessment is calculated by multiplying its assessment rate by the assessment base, which is defined
as the average consolidated total assets less the average tangible equity of the depository institution. The initial base
assessment rate is based on its capital level and CAMELS ratings, certain financial measures to assess an institution’s
ability to withstand asset related stress and funding related stress and, in some cases, additional discretionary
adjustments by the FDIC to reflect additional risk factors.

On June 22, 2020, the FDIC issued a final rule that mitigates the deposit insurance assessment effects of
participating in the Paycheck Protection Program (“PPP”). Pursuant to the final rule, the FDIC will generally remove
the effect of PPP lending in calculating an institution’s deposit insurance assessment. The final rule also provides an
offset to an institution's total assessment amount for the increase in its assessment base attributable to participation in
the PPP and the Money Market Mutual Liquidity Fund.

13

On February 16, 2021, the FDIC adopted a final rule to address the temporary deposit insurance assessment
effects resulting from the optional regulatory capital transition provisions related to the CECL implementation. The
final rule removed the double counting of a portion of the CECL transition amounts in certain financial measures that
are used to determine deposit insurance assessment rates for large or highly complex insured depository institutions.

In October 2022, the FDIC adopted a final rule to increase the initial base deposit insurance assessment rate
schedules uniformly by 2 basis points beginning with the first quarterly assessment period of 2023. The increased
assessment is intended to increase the likelihood that the DIF reserve ratio would reach the statutory minimum of
1.35% by the statutory deadline prescribed under the FDIC's amended restoration plan.

In November 2023, the FDIC adopted a final rule to implement a special assessment to recover the losses to the
DIF associated with several bank failures that occurred during early 2023. The assessment base for the special
assessment is equal to estimated uninsured deposits reported as of December 31, 2022, adjusted to exclude the first
$5 billion, to be collected at a quarterly rate of approximately 3.36 basis points for an anticipated total of eight quarterly
assessment periods, beginning in the first quarter of 2024. As a result, the Company accrued a special assessment of
$19.9 million, or $0.17 per diluted common share net of tax in the fourth quarter of 2023. Under the final rule, the
estimated loss pursuant to the systemic risk determination will be periodically adjusted, and the FDIC has retained the
ability to cease collection early, extend the special assessment collection period and impose a final shortfall special
assessment on a one-time basis. The extent to which any additional future assessments will impact our future deposit
insurance expense is currently uncertain.

Interchange Fees. Under the Durbin Amendment to the Dodd-Frank Act, the Federal Reserve Board adopted
rules establishing standards for assessing whether the interchange fees that may be charged with respect to certain
electronic debit transactions are “reasonable and proportional” to the costs incurred by issuers for processing such
transactions. Interchange fees, or “swipe” fees, are charges that merchants pay to the Bank and other card-issuing
banks for processing electronic payment transactions. Federal Reserve Board rules applicable to financial institutions
that have assets of $10 billion or more provide that the maximum permissible interchange fee for an electronic debit
transaction is the sum of 21 cents per transaction and 5 basis points multiplied by the value of the transaction. An
upward adjustment of no more than 1 cent to an issuer’s debit card interchange fee is allowed if the card issuer develops
and implements policies and procedures reasonably designed to achieve certain fraud-prevention standards. The
Federal Reserve Board also has rules governing routing and exclusivity that require issuers to offer at least two
unaffiliated networks for routing transactions on each debit or prepaid product. On October 25, 2023, the Federal
Reserve Board issued a proposal under which the maximum permissible interchange fee for an electronic debit
transaction would be the sum of 14.4 cents per transaction and 4 basis points multiplied by the value of the transaction.
Furthermore, the fraud-prevention adjustment would increase from a maximum of 1 cent to 1.3 cents. The proposal
would adopt an approach for future adjustments to the interchange fee cap, which would occur every other year based
on issuer cost data gathered by the Federal Reserve from large debit card issuers.

Concentrated Commercial Real Estate Lending. The federal banking agencies, including the FDIC, have
promulgated guidance governing financial institutions with concentrations in commercial real estate lending. The
guidance provides that a bank has a concentration in commercial real estate lending if (1) total reported loans for
construction, land development and other land represent 100% or more of total capital or (2) total reported loans
secured by multifamily and non-farm residential properties and loans for construction, land development and other
land represent 300% or more of total capital and the bank’s commercial real estate loan portfolio has increased 50%
or more during the prior 36 months. Owner occupied loans are excluded from this second category. If a concentration
is present, management must employ heightened risk management practices that address the following key elements:
board and management oversight and strategic planning, portfolio management, development of underwriting
standards, risk assessment and monitoring through market analysis and stress testing, and maintenance of increased
capital levels as needed to support the level of commercial real estate lending.

Community Reinvestment Act. The Community Reinvestment Act of 1977 (“CRA”) and the regulations issued
thereunder are intended to encourage banks to help meet the credit needs of their communities, including low and
moderate income neighborhoods, consistent with the safe and sound operations of the banks. These regulations also
provide for regulatory assessment of a bank’s CRA record when considering applications to establish branches, merger
applications and applications to acquire the assets and assume the liabilities of another bank. The Financial Institutions
Reform, Recovery, and Enforcement Act (“FIRREA”) requires federal banking agencies to make public a rating of a

14

bank’s performance under the CRA. In the case of a financial holding company or a bank holding company, the CRA
performance records of the banks involved in the transaction are reviewed in connection with the filing of an
application to acquire ownership or control of shares or assets of a bank or to merge with any other bank holding
company. An unsatisfactory record can substantially delay or block the transaction.

On October 24, 2023, the Office of the Comptroller of the Currency (“OCC”), Federal Reserve Board, and FDIC
issued a final rule to modernize their respective CRA regulations. The revised rules substantially alter the methodology
for assessing compliance with the CRA, with material aspects taking effect January 1, 2026, and revised data reporting
requirements taking effect January 1, 2027. Among other things, the revised rules evaluate lending outside traditional
assessment areas generated by the growth of non-branch delivery systems, such as online and mobile banking, apply
a metrics-based benchmarking approach to assessment, and clarify eligible CRA activities.

Anti-Money Laundering and Anti-Terrorism Legislation. A major focus of governmental policy on financial
institutions in recent years has been aimed at combating money laundering and terrorist financing. The USA PATRIOT
Act of 2001 (the “USA Patriot Act”) substantially broadened the scope of United States anti-money laundering laws
and regulations by imposing significant new compliance and due diligence obligations, creating new crimes and
penalties and expanding the extra-territorial jurisdiction of the United States. The United States Treasury Department
has issued, and in some cases proposed, a number of regulations that apply various requirements of the USA Patriot
Act to financial institutions. These regulations impose obligations on financial institutions to maintain appropriate
policies, procedures and controls to detect, prevent and report money laundering and terrorist financing and to verify
the identity of their customers. The regulations also impose specific due diligence requirements on financial
institutions that maintain correspondent or private banking relationships with non-U.S. financial institutions or
persons. Failure of a financial institution to maintain and implement adequate programs to combat money laundering
and terrorist financing, or to comply with all of the relevant laws or regulations, could have serious financial, legal
and reputational consequences for the institution and could block or substantially delay a merger or other acquisition
transaction.

The Anti-Money Laundering Act of 2020 (“AMLA”), which amends the Bank Secrecy Act of 1970 (“BSA”),
was enacted in January 2021. The AMLA is intended to be a comprehensive reform and modernization to U.S. bank
secrecy and anti-money laundering laws. Among other things, it codifies a risk-based approach to anti-money
laundering compliance for financial institutions; requires the U.S. Department of the Treasury to promulgate priorities
for anti-money laundering and countering the financing of terrorism policy; requires the development of standards for
evaluating technology and internal processes for BSA compliance; expands enforcement- and investigation-related
authority, including increasing available sanctions for certain BSA violations and expands BSA whistleblower
incentives and protections. Many of the statutory provisions in the AMLA will require additional rulemakings, reports
and other measures, and the impact of the AMLA will depend on, among other things, rulemaking and implementation
guidance. In June 2021, the Financial Crimes Enforcement Network, a bureau of the U.S. Department of the Treasury,
issued the priorities for anti-money laundering and countering the financing of terrorism policy required under the
AMLA. The priorities include: corruption, cybercrime, terrorist financing, fraud, transnational crime, drug trafficking,
human trafficking and proliferation financing.

Office of Foreign Assets Control Regulation. The United States has imposed economic sanctions that affect
transactions with designated foreign countries, nationals and others. These are typically known as the “OFAC” rules
based on their administration by the U.S. Treasury Department Office of Foreign Assets Control (“OFAC”). The
OFAC-administered sanctions targeting countries take many different forms. Generally, however, they contain one or
more of the following elements: (1) restrictions on trade with or investment in a sanctioned country, including
prohibitions against direct or indirect imports from and exports to a sanctioned country and prohibitions on “U.S.
persons” engaging in financial transactions relating to making investments in, or providing investment-related advice
or assistance to, a sanctioned country; and (2) a blocking of assets in which the government or specially designated
nationals of the sanctioned country have an interest, by prohibiting transfers of property subject to U.S. jurisdiction
(including property in the possession or control of U.S. persons). Blocked assets (e.g., property and bank deposits)
cannot be paid out, withdrawn, set off or transferred in any manner without a license from OFAC. Failure to comply
with these sanctions could have serious financial, legal and reputational consequences, including substantial delay or
blocking of a merger or other acquisition transaction.

15

Incentive Compensation. In June 2010, the Federal Reserve Board, OCC and FDIC issued comprehensive final
guidance on incentive compensation policies intended to ensure that the incentive compensation policies of banking
organizations do not undermine the safety and soundness of such organizations by encouraging excessive risk-taking.
The guidance, which covers all employees that have the ability to materially affect the risk profile of an organization,
either individually or as part of a group, is based upon the key principles that a banking organization’s incentive
compensation arrangements should (1) provide incentives that do not encourage risk-taking beyond the organization’s
ability to effectively identify and manage risks, (2) be compatible with effective internal controls and risk management
and (3) be supported by strong corporate governance, including active and effective oversight by the organization’s
Board of Directors. As of December 31, 2023, these proposed rules have not been adopted.

These three principles are incorporated into the proposed revised rules on incentive-based payment
arrangements at specified covered institutions released in May 2016 by a number of federal agencies, including the
Federal Reserve Board, FDIC and SEC. The proposed revised rules would establish general qualitative requirements
applicable to all covered institutions, including the Company and the Bank, that have at least $1 billion in total assets,
which would include (1) prohibiting incentive arrangements that encourage inappropriate risks by providing excessive
compensation; (2) prohibiting incentive arrangements that encourage inappropriate risks that could lead to a material
financial loss; (3) establishing requirements for performance measures to appropriately balance risk and reward; (4)
requiring Board of Director oversight of incentive arrangements; and (5) mandating appropriate record-keeping. Under
the proposed rule, larger financial institutions with total consolidated assets of at least $50 billion would also be subject
to additional requirements.

The Federal Reserve Board and FDIC review, as part of the regular, risk-focused examination process, the
incentive compensation arrangements of banking organizations, such as the Company, that are not “large, complex
banking organizations.” These reviews are tailored to each organization based on the scope and complexity of the
organization’s activities and the prevalence of incentive compensation arrangements. The findings of this supervisory
initiative will be included in reports of examination. Deficiencies will be incorporated into the organization’s
supervisory ratings, which can affect the organization’s ability to make acquisitions and take other actions.
Enforcement actions may be taken against a banking organization if its incentive compensation arrangements, or
related risk-management control or governance processes, pose a risk to the organization’s safety and soundness and
the organization is not taking prompt and effective measures to correct the deficiencies.

In October 2022, the SEC adopted a final rule directing national securities exchanges and associations, including
the NYSE, to implement listing standards that require listed companies to adopt policies mandating the recovery or
“clawback” of excess incentive-based compensation earned by a current or former executive officer during the three
fiscal years preceding the date the listed company is required to prepare an accounting restatement, including to correct
an error that would result in a material misstatement if the error were corrected in the current period or left uncorrected
in the current period. The NYSE’s listing standards pursuant to the SEC’s rule became effective on October 2, 2023.
The Company adopted a compensation recovery policy pursuant to the NYSE listing standards on November 13, 2023.
The Policy is included as Exhibit 97.1 to this Form 10-K.

Cybersecurity. In February 2018, the SEC published interpretive guidance to assist public companies in
preparing disclosures about cybersecurity risks and incidents. These SEC guidelines, and any other regulatory
guidance, are in addition to notification and disclosure requirements under state and federal banking law and
regulations. In addition, in March 2022, the SEC proposed rules that would require disclosure of material cybersecurity
incidents as well as cybersecurity risk management, strategy and governance.

The federal banking regulators regularly issue new guidance and standards, and update existing guidance and
standards, regarding cybersecurity intended to enhance cyber risk management among financial institutions. Financial
institutions are expected to comply with such guidance and standards and to accordingly develop appropriate security
controls and risk management processes. If the Company fails to observe such regulatory guidance or standards, the
Company could be subject to various regulatory sanctions, including financial penalties.

In November 2021, the federal banking agencies adopted a final rule that requires banking organizations to
notify their primary banking regulator within 36 hours of determining that a “computer-security incident” has
materially disrupted or degraded, or is reasonably likely to materially disrupt or degrade, the banking organization’s
ability to carry out banking operations or deliver banking products and services to a material portion of its customer

16

base, its businesses and operations that would result in material loss, or its operations that would impact the stability
of the United States. In 2023, the SEC issued a final rule that requires disclosure of material cybersecurity incidents,
as well as cybersecurity risk management, strategy, and governance. Under this rule, banking organizations that are
SEC registrants must generally disclose information about a material cybersecurity incident within four business days
of determining it is material, with periodic updates as to the status of the incident in subsequent filings as necessary.

State regulators have also been increasingly active in implementing privacy and cybersecurity standards and
regulations. Recently, several states have adopted regulations requiring certain financial institutions to implement
cybersecurity programs, and many states, including Texas, have also recently implemented or modified their data
breach notification, information security and data privacy requirements. The Company expects this trend of state-level
activity in those areas to continue and are continually monitoring developments in the states in which its customers
are located.

Risks and exposures related to cybersecurity attacks, including litigation and enforcement risks, are expected to
be elevated for the foreseeable future due to the rapidly evolving nature and sophistication of these threats, as well as
due to the expanding use of Internet banking, mobile banking and other technology-based products and services by
the Company and its customers.

Legislative and Regulatory Initiatives

From time to time, various legislative and regulatory initiatives are introduced in Congress and state legislatures,
as well as by regulatory agencies. Such initiatives may include proposals to expand or contract the powers of bank
holding companies and depository institutions or proposals to substantially change the financial institution regulatory
system. Such legislation could change banking statutes and the operating environment of the Company in substantial
and unpredictable ways. If enacted, such legislation could increase or decrease the cost of doing business, limit or
expand permissible activities or affect the competitive balance among banks, savings associations, credit unions, and
other financial institutions. The Company cannot predict whether any such legislation will be enacted, and, if enacted,
the effect that it, or any implementing regulations, would have on the financial condition or results of operations of
the Company. A change in statutes, regulations or regulatory policies applicable to the Company or the Bank could
have a material effect on the Company’s business, financial condition and results of operations.

Effect on Economic Environment

The policies of regulatory authorities, including the monetary policy of the Federal Reserve Board, have a
significant effect on the operating results of bank holding companies and their subsidiaries. Among the means
available to the Federal Reserve Board to affect the money supply are open market operations in U.S. government
securities, changes in the discount rate on member bank borrowings and changes in reserve requirements against
member bank deposits. These means are used in varying combinations to influence overall growth and distribution of
bank loans, investments and deposits; and their use may affect interest rates charged on loans or paid for deposits.

Federal Reserve Board monetary policies have materially affected the operating results of commercial banks in
the past and are expected to continue to do so in the future. The nature of future monetary policies and the effect of
such policies on the business and earnings of the Company and its subsidiaries cannot be predicted.

17

ITEM 1A. RISK FACTORS

An investment in the Company’s common stock involves risks. The following is a description of the material
risks and uncertainties that the Company believes affect its business and an investment in the common stock.
Additional risks and uncertainties that the Company is unaware of, or that it currently deems immaterial, also may
become important factors that affect the Company and its business. If any of the risks described in this Annual Report
on Form 10-K were to occur, the Company’s financial condition, results of operations and cash flows could be
materially and adversely affected. If this were to happen, the value of the common stock could decline significantly
and all or part of an investment could be lost.

Risks Associated with the Company’s Business

Interest Rate Risks

The Company’s business is subject to interest rate risk, and fluctuations in interest rates may adversely affect its
financial condition and results of operations.

The majority of the Company’s assets are monetary in nature, and, as a result, the Company is subject to
significant risk from changes in interest rates. Changes in interest rates can impact the Company’s net interest income
as well as the valuation of its assets and liabilities. The Company’s earnings are significantly dependent on its net
interest income. Net interest income is the difference between the interest income earned on loans, investments and
other interest-earning assets and the interest expense paid on deposits, borrowings and other interest-bearing liabilities.

Interest rates are highly sensitive to many factors that are beyond the Company’s control, including general
economic conditions, inflationary trends, changes in government spending and debt issuances and policies of various
governmental and regulatory agencies and, in particular, the Federal Open Market Committee. Changes in monetary
policy, including changes in interest rates, could influence the interest the Company receives on loans and securities
and the amount of interest it pays on deposits and borrowings, and could also affect (1) the Company’s ability to
originate loans, such as decreased demand due to higher interest rates, and obtain deposits, (2) the fair value of the
Company’s financial assets and liabilities and (3) the average duration of the Company’s mortgage-backed securities
portfolio. Beginning early in 2022, in response to growing signs of inflation, the Federal Reserve Board increased
interest rates rapidly. Further, the Federal Reserve Board announced an intention to take further actions to mitigate
inflationary pressures. Rapid changes in interest rates may make it difficult for the Company to balance its loan and
deposit portfolios. If the interest rates paid on deposits and other borrowings increase at a faster rate than the interest
rates received on loans and other investments, the Company’s net interest income, and therefore earnings, could be
adversely affected. Earnings also could be adversely affected if the interest rates received on loans and other
investments decrease more quickly than the interest rates paid on deposits and other borrowings. Decreasing interest
rates reduces the Company’s yield on its variable rate loans and on its new loans, which reduces its net interest income.
In addition, lower interest rates may reduce the Company’s realized yields on investment securities which would
reduce its net interest income and cause downward pressure on net interest margin in future periods. Further, the
Company’s assets and liabilities may react differently to changes in overall market rates or conditions because there
may be mismatches between the repricing or maturity characteristics of the assets and liabilities. Any substantial,
unexpected, prolonged change in market interest rates could have a material adverse effect on the Company’s business,
financial condition and results of operations.

Although the Federal Reserve Board increased the target federal funds rate in 2023 to combat inflationary trends,
the Federal Reserve Board held the federal funds rate steady in December 2023 for the third consecutive time and
indicated that the rate is likely to be decreased in 2024 and beyond. The Company is unable to predict changes in
interest rates, which are affected by factors beyond its control, including inflation, deflation, recession, unemployment,
money supply, and other changes in financial markets.

18

Credit and Lending Risks

The Company’s business depends on its ability to successfully manage credit risk.

The Company’s business depends on its ability to successfully measure and manage credit risk. As a lender, the
Company is exposed to the risk that the principal of, or interest on, a loan will not be repaid timely or at all or that the
value of any collateral supporting a loan will be insufficient to cover the Company’s outstanding exposure. In addition,
the Company is exposed to risks with respect to the period of time over which the loan may be repaid, risks relating
to proper loan underwriting, risks resulting from changes in economic and industry conditions, and risks inherent in
dealing with individual loans and borrowers. The creditworthiness of a borrower is affected by many factors including
local market conditions and general economic conditions. If the overall economic climate in the United States,
generally, or the Company’s market areas, specifically, experiences material disruption, the Company’s borrowers
may experience difficulties in repaying their loans, the collateral the Company holds may decrease in value or become
illiquid, and the level of nonperforming loans, charge-offs and delinquencies could rise and require significant
additional provisions for credit losses. Additional factors related to the credit quality of commercial loans include the
quality of the management of the business and the borrower's ability to properly evaluate changes in the supply and
demand characteristics affecting their market for products and services, to evaluate regulatory changes affecting their
products and services, such as climate change regulation, and to effectively respond to those changes. Additional
factors related to the credit quality of commercial real estate loans include tenant vacancy rates and the quality of
management of the property.

In addition, financial markets and global supply chains may be adversely affected by the current or anticipated
impact of military conflict, including conflicts in Ukraine and the Middle East, terrorism or other geopolitical events.
Current economic conditions are significantly affected by elevated levels of inflation and rising interest rates
throughout 2022 and 2023. Continuing inflationary pressures in 2024 could lead to increased costs to the Company’s
customers, making it more difficult for them to repay their loans or other obligations, which would increase the
Company’s credit risk. Sustained higher interest rates by the Federal Reserve Board may be needed to address
persistent inflationary price pressures, which could push down asset prices and weaken economic activity. Meanwhile,
economic and inflationary pressure on consumers and uncertainty regarding the prospects for economic improvement
could alter consumer and business spending, borrowing and savings habits. A deterioration in economic conditions in
the United States and the Company’s markets could result in an increase in loan delinquencies and nonperforming
assets, decreases in loan collateral values and a decrease in demand for its products and services, all of which, in turn,
would adversely affect its business, financial condition and results of operations. Furthermore, evolving responses
from federal and state governments and other regulators, and the Company’s customers or vendors, to new challenges
such as climate change have impacted and could continue to impact the economic and political conditions under which
the Company operates, which could have a material adverse effect on the Company’s business, financial condition
and results of operations.

The Company’s risk management practices, such as monitoring the concentration of the Company’s loans within
specific industries and the Company’s credit approval, review and administrative practices, may not adequately reduce
credit risk, and the Company’s credit administration personnel, policies and procedures may not adequately adapt to
changes in economic or any other conditions affecting customers and the quality of the loan portfolio. Many of the
Company’s loans are made to businesses that are less able to withstand competitive, economic and financial pressures
than larger borrowers. Consequently, the Company may have significant exposure if any of these borrowers becomes
unable to pay their loan obligations as a result of economic or market conditions, or personal circumstances, such as
divorce or death. A failure to effectively measure and limit the credit risk associated with the Company’s loan portfolio
may result in loan defaults, foreclosures and additional charge-offs, and may require the Company to significantly
increase its allowance for credit losses, each of which could adversely affect the Company’s net income. As a result,
the Company’s inability to successfully manage credit risk could have a material adverse effect on the Company’s
business, financial condition and results of operations.

The Company’s allowance for credit losses may not be sufficient to cover actual credit losses, which could adversely
affect its earnings.

As a lender, the Company is exposed to the risk that its loan customers may not repay their loans according to
the terms of these loans and the collateral securing the payment of these loans may be insufficient to fully compensate
the Company for the outstanding balance of the loan plus the costs to dispose of the collateral. The Company maintains

19

an allowance for credit losses in an attempt to cover estimated losses inherent in its loan portfolio. Additional credit
losses could occur in the future and may occur at a rate greater than the Company has experienced to date. The
determination of the appropriate level of the allowance inherently involves a high degree of subjectivity and requires
the Company to make significant estimates of current credit risks, future trends and general economic conditions,
including inflation and recession, all of which may undergo material changes. If the Company’s assumptions prove to
be incorrect or if it experiences significant credit losses in future periods, its current allowance may not be sufficient
to cover actual credit losses and adjustments may be necessary to allow for different economic conditions or adverse
developments in its loan portfolio. A material addition to the allowance could cause net income, and possibly capital,
to decrease.

In addition, federal and state regulators periodically review the Company’s allowance for credit losses and may
require the Company to increase its provision for credit losses or recognize further charge-offs, based on judgments
different than those of the Company’s management. An increase in the Company’s allowance for credit losses or
charge-offs as required by these regulatory agencies could have a material adverse effect on the Company’s operating
results and financial condition.

The Company’s profitability depends significantly on local economic conditions.

The Company’s success depends primarily on the general economic conditions of the primary markets in Texas
and Oklahoma in which it operates and where its loans are concentrated. The local economic conditions in Texas and
Oklahoma have a significant impact on the Company’s commercial, real estate and construction, land development
and other land loans; the ability of its borrowers to repay their loans; and the value of the collateral securing these
loans. Accordingly, if the population or income growth in the Company’s market areas is slower than projected,
income levels, deposits and housing starts could be adversely affected and could result in a reduction of the Company’s
expansion, growth and profitability. In addition, due to the large number of oil and gas companies in the Company’s
market areas, the volatility in oil prices may negatively impact economic conditions in these areas. If the Company’s
market areas experience a downturn or a recession for a prolonged period of time, the Company could experience
significant increases in nonperforming loans, which could lead to operating losses, impaired liquidity and eroding
capital. A significant decline in general economic conditions, caused by inflation, an increase or decline in commodity
prices, recession, weather extremes, acts of terrorism, outbreaks of hostilities or other international or domestic
calamities, unemployment or other factors could impact these local economic conditions and could negatively affect
the Company’s financial condition, results of operations and cash flows.

The Company’s dependence on loans secured by real estate subjects it to risks relating to fluctuations in the real
estate market that could adversely affect its financial condition, results of operations and cash flows.

Approximately 82.6% of the Company’s total loans as of December 31, 2023 consisted of loans included in the
real estate loan portfolio, with 29.6% in commercial real estate (including farmland and multifamily residential),
38.5% in residential real estate (including home equity) and 14.5% in construction, land development and other land
loans. The real estate collateral in each case provides an alternate source of repayment in the event of default by the
borrower and may deteriorate in value during the time the credit is extended. The market value for real estate can
fluctuate significantly over a relatively short period as a result of conditions in the Company’s primary market areas,
due to economic downturns, changes in the economic health of industries heavily concentrated in a particular market
area, or changes in market interest rates. A weakening of the real estate market in the Company’s primary market
areas could have an adverse effect on the demand for new loans, the ability of borrowers to repay outstanding loans,
the value of real estate and other collateral securing the loans and the value of real estate owned by the Company. If
real estate values decline, it is also more likely that the Company would be required to increase its allowance for credit
losses, which could adversely affect its financial condition, results of operations and cash flows.

The Company’s commercial real estate and commercial loans expose it to increased credit risks, and these risks
will increase if the Company succeeds in increasing these types of loans.

The Company has emphasized both new and existing loan products, focusing on managing its commercial real
estate (including farmland and multifamily residential) and commercial loan portfolios, and intends to continue to
increase its lending activities and acquire loans in possible future acquisitions. As a result, commercial real estate and
commercial loans as a proportion of its portfolio could increase. As of December 31, 2023, commercial real estate
(including farmland and multifamily residential) and commercial loans totaled $8.57 billion. In general, commercial

20

real estate loans and commercial loans pose greater credit risks than do owner-occupied residential real estate loans.
These types of loans are also typically larger than residential real estate loans. Accordingly, the deterioration of one
or several of these loans could cause a significant increase in nonperforming loans, which could result in a loss of
earnings from these loans and an increase in the provision for credit losses and net charge-offs.

The Company makes both secured and some unsecured commercial loans. Unsecured loans generally involve a
higher degree of risk of loss than do secured loans because, without collateral, repayment is wholly dependent upon
the success of the borrowers’ businesses. Secured commercial loans are generally collateralized by accounts
receivable, inventory, equipment or other assets owned by the borrower and include a personal guaranty of the business
owner. Compared to real estate, that type of collateral is more difficult to monitor, its value is harder to ascertain, it
may depreciate more rapidly and it may not be as readily saleable if repossessed. Further, commercial loans generally
will be serviced primarily from the operation of the business, which may not be successful, while commercial real
estate loans generally will be serviced from income on the properties securing the loans. As the Company’s various
commercial loan portfolios increase, the corresponding risks and potential for losses from these loans will also
increase.

The Company may be adversely affected by weaknesses in the commercial real estate market.

As of December 31, 2023, commercial real estate loans (including multifamily residential and excluding
farmland) comprised approximately 26.8% of the Company’s loan portfolio. Commercial real estate loans generally
involve a greater degree of credit risk than residential real estate loans because they typically have larger balances and
are more affected by adverse conditions in the economy. Because payments on loans secured by commercial real
estate often depend upon the successful operation and management of the properties and the businesses which operate
from within them, repayment of such loans may be affected by factors outside the borrower’s control, such as adverse
conditions in the real estate market or the economy or changes in government regulations. Commercial real estate
markets have been impacted by the economic disruptions caused by the COVID-19 pandemic. The COVID-19
pandemic has also been a catalyst for the evolution of various remote work options that could have an adverse effect
on the long-term performance of some types of office properties within the Company’s commercial real estate
portfolio. A failure by the Company to have adequate risk management policies, procedures and controls could
adversely affect the Company’s ability to increase this portfolio going forward and could result in an increased rate of
delinquencies in, and increased losses from, this portfolio, which, accordingly, could have a material adverse effect
on the Company’s business, financial condition and results of operations.

The Company’s Warehouse Purchase Program balances can fluctuate widely.

Because Warehouse Purchase Program balances are contingent upon residential mortgage lending activity,
changes in the residential real estate market nationwide can lead to wide fluctuations of balances in this product,
materially impacting both interest and non-interest income. Additionally, Warehouse Purchase Program period-end
balances are generally higher than the average balance during the period due to increased mortgage activity that occurs
at the end of a month, which can significantly impact the Company’s reported capital ratios.

The Company’s loan portfolio, and specifically its energy lending portfolio, could be adversely affected by declines
in the prices of oil and natural gas, as well as other factors.

As of December 31, 2023, the Company had $368.3 million (net of discount and excluding PPP loans totaling
$2.6 million) in funded commitments outstanding to oil and gas production and service companies and $471.7 million
in unfunded commitments, for a total of $840.0 million (net of discount and excluding PPP loans totaling $2.6 million).
The funded commitments to oil and gas production and service companies are reported as commercial and industrial
loans and represented 1.7% of total loans, excluding Warehouse Purchase Program loans. As a result, the factors that
impact the energy sector may have an effect on the Company. Companies with exposure to the energy sector, whether
directly or indirectly, are subject to volatile fluctuations in price and supply of oil and gas. Many factors affect the
supply of and demand for crude oil and natural gas and, therefore, influence prices of these commodities, including:

•

•

domestic and foreign supply of oil and natural gas, including increased availability of non-traditional
energy resources such as shale oil and gas;

prices, and expectations about future prices, of oil and natural gas;

21

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

domestic and worldwide economic conditions, and the resulting global demand for oil and natural gas;

the price and quantity of imports of foreign oil and natural gas including the ability of the Organization
of Petroleum Exporting Countries (“OPEC”) to set and maintain production levels for oil, and decisions
by OPEC and non-OPEC producers to change production levels;

sanctions imposed by the U.S., the European Union, or other governments against oil producing countries;

the cost of exploring for, developing, producing and delivering oil and natural gas;

the level of excess production capacity, available pipeline, storage and other transportation capacity;

lead times associated with acquiring equipment and products and availability of qualified personnel;

the expected rates of decline in production from existing and prospective wells;

the discovery rates of new oil and gas reserves;

federal, state and local regulation of exploration and drilling activities and oil and gas exports, including
climate change regulation;

legislative and regulatory interest within federal, state and local governments to stop, significantly limit
or regulate hydraulic fracturing activities (also known as “fracking”) or emissions;

weather conditions, including hurricanes, that can affect oil and natural gas operations over a wide area
and severe winter weather that can interfere with oil and gas development and production operations;

political instability and social unrest throughout the world, such as in Ukraine and the Middle East, and
particularly in oil and natural gas producing countries;

advances in exploration, development and production technologies or in technologies affecting energy
consumption (such as fracking);

the price and availability of alternative fuel and energy sources;

the transition to alternate energy sources, like wind and solar;

uncertainty in capital and commodities markets; and

changes in the value of the U.S. dollar relative to other major global currencies.

Further, the economy in Texas as a whole could be negatively impacted if there are a high number of jobs lost
related to a decline in oil production in the state, or if the impact of lower oil prices negatively affects other industries.
A decline in the Texas economy related to oil production decline could impact the Company’s loan portfolios outside
of the energy portfolio, if borrowers experience unemployment or loss of income and are unable to make payments
on their loans.

The Company is subject to losses due to fraudulent and negligent acts.

Financial institutions are inherently exposed to fraud risk. Fraudulent activity can take many forms and has
escalated as more tools for accessing financial services emerge, such as real-time payments. Fraud schemes are broad
and continuously evolving. A fraud can be perpetrated by a customer of the Company, an employee, a vendor, or
members of the general public. The Company is subject to fraud risk in connection with the origination of loans, ACH
transactions, wire transactions, digital payments, ATM transactions, checking and other transactions. Although the
Company seeks to mitigate fraud risk and losses through continued investment in systems, resources, and controls,
the Company’s efforts may not be effective in detecting fraud and the Company could experience fraud losses or incur
costs or other damage related to such fraud, at levels that adversely affect its financial results or reputation.

22

The Company is subject to losses resulting from fraudulent and negligent acts on the part of loan applicants,
correspondents or other third parties.

The Company relies heavily upon information supplied by third parties, including the information contained in
credit applications, property appraisals, title information, equipment pricing and valuation and employment and
income documentation, in deciding which loans the Company will originate, as well as the terms of those loans. If any
of the information upon which the Company relies is misrepresented, either fraudulently or inadvertently, and the
misrepresentation is not detected prior to asset funding, the value of the asset may be significantly lower than expected,
or the Company may fund a loan that it would not have funded or on terms it would not have extended. Whether a
misrepresentation is made by the applicant or another third party, the Company generally bears the risk of loss
associated with the misrepresentation. A loan subject to a material misrepresentation is typically unsellable or subject
to repurchase if it is sold prior to detection of the misrepresentation. The sources of the misrepresentations are often
difficult to locate, and it is often difficult to recover any of the monetary losses the Company may suffer. The Company
believes it has underwriting and operational controls in place to prevent or detect such fraud, but these controls may
not be effective in detecting fraud and the Company could experience fraud losses or incur costs or other damage
related to such fraud, at levels that adversely affect financial results or reputation. The Company’s lending customers
may also experience fraud in their businesses which could adversely affect their ability to repay their loans or make
use of services. The Company’s and its customers’ exposure to fraud may increase the Company’s financial risk and
reputation risk as it may result in unexpected loan losses that exceed those that have been provided for in the allowance
for credit losses. Some level of fraud loss is unavoidable, and the risk of loss cannot be eliminated.

The Company’s financial conditions and results of operations may be adversely affected by changes in accounting
policies, standards and interpretations.

The Financial Accounting Standards Board (“FASB”) and other bodies that establish accounting standards
periodically change the financial accounting and reporting standards governing the preparation of the Company’s
financial statements. Additionally, those bodies that establish and interpret the accounting standards (such as the
FASB, SEC and banking regulators) may change prior interpretations or positions on how these standards should be
applied. Changes resulting from these new standards may result in materially different financial results and may
require that the Company changes how it processes, analyzes and reports financial information and that it changes
financial reporting controls.

The preparation of consolidated financial statements in conformity with GAAP, including the accounting rules
and regulations of the SEC and the FASB, requires management to make significant estimates and assumptions that
impact the Company’s financial statements by affecting the value of its assets or liabilities and results of operations.
Some of the Company’s accounting policies are critical because they require management to make difficult, subjective
and complex judgments about matters that are inherently uncertain and because materially different amounts may be
reported if different estimates or assumptions are used. If such estimates or assumptions underlying its financial
statements are incorrect, the Company’s financial condition and results of operations could be adversely affected.

The Company is subject to environmental liability risk associated with lending activities.

A significant portion of the Company’s loan portfolio is secured by real property. During the ordinary course of
business, the Company may foreclose on and take title to properties securing certain loans, and there is a risk that
hazardous or toxic substances could be found on these properties. If hazardous or toxic substances are found, the
Company may be liable for remediation costs, as well as for personal injury and property damage. Environmental laws
may require the Company to incur substantial expenses and may materially reduce the affected property’s value or
limit the Company’s ability to use or sell the affected property. In addition, future laws or more stringent
interpretations or enforcement policies with respect to existing laws may increase the Company’s exposure to
environmental liability. Although the Company has policies and procedures to perform an environmental review
before initiating any foreclosure action on real property, these reviews may not be sufficient to detect all potential
environmental hazards. The remediation costs and any other financial liabilities associated with an environmental
hazard could have a material adverse effect on the Company’s financial condition and results of operations.

23

Liquidity Risks

Liquidity risk could impair the Company’s ability to fund operations and jeopardize its financial condition.

Liquidity is essential to the Company’s business, and it monitors and manages its liquidity daily. An inability
to raise funds through deposits, borrowings, the sale of loans and other sources could have a substantial negative effect
on the Company’s liquidity. The Company’s access to funding sources in amounts adequate to finance its activities or
on terms which are acceptable to it could be impaired by factors that affect the Company specifically or the financial
services industry or economy in general. Factors that could detrimentally impact the Company’s access to liquidity
sources include a decrease in the level of its business activity as a result of a downturn in the markets in which its
loans are concentrated or adverse regulatory action against it. The Company’s ability to borrow could also be impaired
by factors that are not specific to it, such as a disruption in the financial markets or negative views and expectations
about the prospects for the financial services industry in light of the turmoil faced by banking organizations in 2023
and the continued deterioration in credit markets.

The Company relies on customer deposits as a significant source of funding, and its deposits may decrease in the
future.

The Company relies on customer deposits as a significant source of funding. Competition among U.S. banks
for customer deposits is intense, may increase the cost of deposits or prevent new deposits, and may otherwise
negatively affect the Company’s ability to grow its deposit base. The Company’s deposit accounts may decrease in
the future, and any such decrease could have an adverse impact on the Company’s sources of funding, which impact
could be material. Any changes the Company makes to the rates offered on its deposit products to remain competitive
with other financial institutions may adversely affect its profitability and liquidity. The demand for the deposit
products the Company offers may also decline due to a variety of factors such as demographic patterns, changes in
customer preferences, changes in interest rates, payment of interest on demand deposits by other financial institutions,
reductions in consumers’ disposable income, regulatory actions that decrease customer access to particular products
or the availability of competing products, including from new financial technology competitors or competitors that
provide customers with alternate investment options.

Recent negative developments affecting the banking industry, and resulting media coverage, have eroded customer
confidence in the banking system.

The high-profile closures of various banks in 2023, and concerns about similar future events, have generated
significant market volatility among publicly traded bank holding companies and, in particular, regional banks like the
Company. These market developments have negatively impacted customer confidence in the safety and soundness of
regional banks. As a result, customers may choose to maintain deposits with larger financial institutions or invest in
higher yielding short-term fixed income securities, all of which could materially adversely impact the Company’s
liquidity, loan funding capacity, net interest margin, capital and results of operations. While the Department of the
Treasury, the Federal Reserve Board, and the FDIC took action to ensure that depositors of these failed banks had
access to their deposits, including uninsured deposit accounts, such actions may not be successful in restoring customer
confidence in regional banks and the banking system more broadly.

The Company may need to raise additional capital in the future and such capital may not be available when needed
on acceptable terms or at all.

The Company may need to raise additional capital in the future to provide it with sufficient capital resources
and liquidity to meet regulatory capital requirements or its commitments and business needs. In addition, the Company
may elect to raise additional capital to support its business or to finance acquisitions, if any. If needed, the Company’s
ability to raise additional capital will depend on many things, including conditions in the capital markets at that time,
which are outside its control, and its financial performance.

Such capital may not be available to the Company on acceptable terms or at all. Any occurrence that may limit
the Company’s access to the capital markets, such as a decline in the confidence of investors, depositors of the Bank
or counterparties participating in the capital markets, may adversely affect the Company’s capital costs and its ability
to raise capital and, in turn, its liquidity. Moreover, if the Company needs to raise capital in the future, it may have to
do so when many other financial institutions are also seeking to raise capital and would have to compete with those

24

institutions for investors. An inability to raise additional capital on acceptable terms when needed could have a
material adverse effect on the Company’s business, financial condition and results of operations.

The fair value of the Company’s investment securities can fluctuate due to factors outside of its control.

Factors beyond the Company’s control can significantly influence the fair value of securities in its investment
portfolio and can cause potential adverse changes to the fair value of these securities. These factors include, but are
not limited to, rating agency actions in respect of the securities, defaults by the issuer or with respect to the underlying
securities, and changes in market interest rates and continued instability in the capital markets. Any of these factors,
among others, could cause an increase in the amount of the allowance for credit losses as it pertains to available for
sale or held-to-maturity debt securities, which could have an adverse effect on the Company’s business, results of
operations, financial condition and future prospects. The process for determining if a security has a credit loss often
requires complex, subjective judgments about whether there has been a significant deterioration in the financial
condition of the issuer, whether management has the intent or ability to hold a security for a period of time sufficient
to allow for any anticipated recovery in fair value, the future financial performance and liquidity of the issuer and any
collateral underlying the security, and other relevant factors.

Strategic Risks

If the Company is not able to continue its historical levels of growth, it may not be able to maintain its historical
earnings trends.

To achieve its past levels of growth, the Company has focused on both internal growth and acquisitions. The
Company may not be able to sustain its historical rate of growth or may not be able to grow at all in the future. More
specifically, the Company may not be able to obtain the financing necessary to fund additional growth and may not
be able to find suitable acquisition candidates. Various factors, such as economic conditions, competition and
heightened regulatory scrutiny, may impede or prohibit the opening of new banking centers and the completion of
acquisitions. Further, the Company may be unable to attract and retain experienced bankers, which could adversely
affect its internal growth. If the Company is not able to continue its historical levels of growth, it may not be able to
maintain its historical earnings trends.

If the Company is unable to manage its growth effectively, its operations and profitability could be negatively
affected.

The Company faces a variety of risks and difficulties pursuing its growth strategy, including:

•

•

•

•

•

•

•

•

finding suitable markets for expansion;

finding suitable candidates for acquisition;

attracting funding to support additional growth;

maintaining asset quality;

attracting and retaining qualified management;

managing execution risks;

maintaining adequate regulatory capital; and

scaling technology platforms.

In addition, in order to manage its growth and maintain adequate information and reporting systems within its
organization, the Company must identify, hire and retain additional qualified associates, particularly in the accounting
and operational areas of its business.

If the Company does not manage its growth effectively, its business, financial condition, results of operations
and future prospects could be negatively affected, and the Company may not be able to continue to implement its
business strategy and successfully conduct its operations.

25

If the Company is unable to identify and acquire other financial institutions and successfully integrate its acquired
businesses, its business and earnings may be negatively affected.

The market for acquisitions remains highly competitive, and the Company may be unable to find acquisition
candidates in the future that fit its acquisition and growth strategy. To the extent that the Company is unable to find
suitable acquisition candidates, an important component of its growth strategy may be lost. Additionally, the market
for bank acquisitions was significantly and adversely impacted in 2023, and remains impacted, by a number of factors,
including:

•

•

•

•

•

increased regulatory scrutiny;

elevated interest rates;

declining financial institution stock value

lower fair market values of investment securities portfolios; and

high-profile regional bank failures and the resulting effects therefrom.

To the extent these factors, or other factors outside of the Company’s control, persist or arise, the Company’s

ability to pursue and consummate acquisitions may be adversely impacted.

Acquisitions of financial institutions, such as the recent acquisition of First Bancshares and the pending
acquisition of Lone Star, involve operational risks and uncertainties. Acquired companies may have unforeseen
liabilities, exposure to asset quality problems, key employee and customer retention problems and other problems that
could negatively affect the Company’s organization. The Company may not be able to complete future acquisitions;
and, if completed, the Company may not be able to successfully integrate the operations, management, products and
services of the entities that it acquires and eliminate redundancies. The integration process could result in the loss of
key employees or disruption of the combined entity’s ongoing business or inconsistencies in standards, controls,
procedures and policies that adversely affect the Company’s ability to maintain relationships with customers and
employees or achieve the anticipated benefits of the transaction. The integration process may also require significant
time and attention from the Company’s management that they would otherwise direct at servicing existing business
and developing new business. The Company’s inability to find suitable acquisition candidates or failure to successfully
integrate the entities it acquires into its existing operations may increase its operating costs significantly and adversely
affect its business and earnings. Acquisitions may also result in potential dilution to existing shareholders of the
Company’s earnings per share if the Company issues common stock in connection with an acquisition.

Regulatory approvals for acquisitions may be delayed, impeded, or prohibited.

Acquisitions by financial institutions are subject to approval by a variety of federal and state regulatory agencies.
If the Company fails to receive the appropriate regulatory approvals, it will not be able to consummate an acquisition
that it believes is in the Company’s best interests. Among other things, the Company’s regulators consider its capital,
liquidity, profitability, regulatory compliance, including with respect to anti-money laundering obligations, consumer
protection laws and CRA obligations and levels of goodwill and intangibles when considering acquisition and
expansion proposals. The process for obtaining these required regulatory approvals has become substantially more
difficult in recent years and may become even more challenging following the review of the merger application process
by the federal banking agencies and potentially the CFPB and the review of the competitive effects process by the
Department of Justice. Regulatory approvals have been and could continue to be delayed, impeded, restrictively
conditioned or denied due to existing or new regulatory issues the Company has, or may have, with regulatory
agencies, including, without limitation, issues related to Bank Secrecy Act compliance, Community Reinvestment Act
issues, fair lending laws, fair housing laws, consumer protection laws, unfair, deceptive, or abusive acts or practices
regulations and other similar laws and regulations. The Company may fail to pursue, evaluate or complete strategic
and competitively significant acquisition opportunities as a result of its inability, or perceived or anticipated inability,
to obtain regulatory approvals in a timely manner, under reasonable conditions or at all. Difficulties associated with
potential acquisitions that may result from these factors could have a material adverse effect on the Company’s
business, financial condition and results of operations.

26

If the goodwill that the Company recorded in connection with a business acquisition becomes impaired, it could
require charges to earnings.

Goodwill represents the amount by which the acquisition cost exceeds the fair value of net assets the Company
acquired in the purchase of another financial institution. The Company reviews goodwill for impairment at least
annually, or more frequently if events or changes in circumstances indicate the carrying value of the asset might be
impaired.

The Company determines impairment by comparing the implied fair value of the reporting unit goodwill with
the carrying amount of that goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair
value of that goodwill, an impairment loss is recognized in an amount equal to that excess. Any such adjustments are
reflected in the Company’s results of operations in the periods in which they become known. At December 31, 2023,
the Company’s goodwill totaled $3.40 billion. Although the Company has not recorded any such impairment charges
since it initially recorded the goodwill, the Company’s future evaluations of goodwill could result in findings of
impairment and related write-downs, which may have a material adverse effect on its financial condition and results
of operations.

Operational Risks

The Company’s accounting estimates and risk management processes rely on analytical and forecasting models
and tools that may prove to be inaccurate.

The processes the Company uses to estimate its expected credit losses and to measure the fair value of financial
instruments, as well as the processes used to estimate the effects of changing interest rates and other market measures
on the Company’s financial condition and results of operations, depend upon the use of analytical and forecasting
models and tools. These models and tools reflect assumptions that may not be accurate, particularly in times of market
stress or other unforeseen circumstances. Even if these assumptions are accurate, the models and tools may prove to
be inadequate or inaccurate because of other flaws in their design or their implementation. Any such failure in the
Company’s analytical or forecasting models and tools could have a material adverse effect on the Company’s business,
financial condition and results of operations.

An interruption in or breach in security of the Company’s information systems may result in a loss of customer
business and have an adverse effect on the Company’s results of operations, financial condition and cash flows.

The Company relies heavily on communications and information systems to conduct its business and store
sensitive data. Any failure, interruption or breach in security of these systems, whether caused by physical damage,
hackers, viruses or other malware, could jeopardize the security of information stored in and transmitted through the
Company’s computer systems and network infrastructure as well as result in failures or disruptions in the Company’s
customer relationship management, general ledger, deposits, servicing or loan origination systems. The amount of
specific “cyber” insurance coverage that the Company maintains and expects would apply in the event of various
breach scenarios may not be adequate in any particular case. In addition, cyber threat scenarios are inherently difficult
to predict and can take many forms, some of which may not be covered under the Company’s cyber insurance
coverage. Security measures that the Company, with the help of third-party service providers, has implemented or
intends to continue to implement to prevent damage from cyberattacks may not entirely mitigate these risks. In
addition, increases in cyber threats and the sophistication of bad actors, advances in computer capabilities, new
discoveries in the field of cryptography or other developments could result in a compromise or breach of the algorithms
the Company and its third-party service providers use to protect client transaction data. The Company’s efforts to
maintain the security and integrity of its information systems and its measures to manage the risks of a security breach
or disruption may not be effective, and attempted security breaches or disruptions could be successful or damaging.
Breaches also may occur as a result of remote working arrangements. The occurrence of any such failures,
interruptions or security breaches could result in significant disruptions to the Company’s operations and could
damage the Company’s reputation, result in a loss of customer business, subject the Company to additional regulatory
scrutiny or expose the Company to civil litigation and possible financial liability, any of which could have a material
adverse effect on the Company’s results of operations, financial condition and cash flows.

Breaches of the Company’s or vendors’ systems, thefts of data and other breaches and criminal activity may
result in significant costs to respond or remediate losses, damage to the Company’s customer relationships, regulatory

27

scrutiny and enforcement and loss of future business opportunities due to reputational damage. Even the most well-
protected information, networks, systems and facilities remain potentially vulnerable because attempted security
breaches, particularly cyber-attacks and intrusions, or disruptions will occur in the future, and because the techniques
used in such attempts are rapidly and constantly evolving and generally are not recognized until launched against a
target, in some cases are designed not to be detected and, in fact, may not be detected for a period of time or at all.
Accordingly, the Company may be unable to anticipate or be prepared for these techniques or to implement adequate
security barriers or other preventative measures, and thus it is not possible for the Company to entirely mitigate this
risk. Data privacy laws also continue to evolve, with states increasingly proposing or enacting legislation that relates
to data privacy and data protection. The Company may be required to incur additional expense to comply with these
evolving regulations and could face penalties for violating any of these regulations.

The Company is subject to certain risks in connection with its use of technology.

The financial services industry is undergoing rapid technological changes with frequent introductions of new
technology-driven products and services. The Company’s future success depends in part upon its ability to address
the needs of its customers by using technology to provide products and services that will satisfy customer demands
for convenience as well as create additional efficiencies in its operations. Many of the Company’s competitors have
substantially greater resources to invest in technological improvements. The Company may not be able to effectively
implement new technology-driven products and services or be successful in marketing these products and services to
its customers, which may negatively affect the Company’s results of operations, financial condition and cash flows.
The Company also may not succeed in anticipating its future technology needs, the technology demands of its
customers, or the competitive landscape for technology. Further, as technology advances, the ability to initiate
transactions and access data has become more widely distributed among mobile devices, personal computers,
automated teller machines, remote deposit capture sites and similar access points. These technological advances
increase cybersecurity risk. The Company’s programs that are intended to prevent or limit the effects of cybersecurity
risk may not be sufficient to eliminate all unauthorized transactions or unauthorized access to customer information.
The financial, reputational and regulatory impact of unauthorized transactions or unauthorized access to customer
information could be significant.

The Company’s operations rely on external vendors, which may fail to provide adequate services.

The Company relies on certain external vendors to provide products and services necessary to maintain its day-
to-day operations. These third parties provide key components of the Company’s business operations such as data
processing, recording and monitoring transactions, online banking interfaces and services, internet connections and
network access, but the Company does not control their actions. Any complications caused by these third parties,
including those resulting from disruptions in communication services provided by a vendor, failure of a vendor to
handle current or higher volumes, cyber-attacks and security breaches at a vendor, failure of a vendor to provide
services for any reason or poor performance of services, could adversely affect the Company’s ability to deliver
products and services to its customers and otherwise conduct its business. Financial or operational difficulties of a
third-party vendor could also hurt the Company’s operations if those difficulties interfere with the vendor’s ability to
provide services. Furthermore, the Company’s vendors could also be sources of operational and information security
risk, including from breakdowns or failures of their own systems or capacity constraints, and reputational risk.
Replacing these third-party vendors could also create significant delay and expense. Problems caused by external
vendors could be disruptive to the Company’s operations, which could have a material adverse impact on the
Company’s business and, in turn, the Company’s financial condition and results of operations.

The Company’s business may be adversely affected by consolidations of technology vendors.

The Company relies on certain external vendors for core products and services. Consolidations among core
vendors may have the effect of decreasing price competition that may lead to higher vendor costs and may also increase
systemic risk from vendors that could affect the Company’s operations.

28

The Company’s business may be adversely affected by security breaches at third parties.

The Company’s customers interact with their own and other third-party systems, which pose operational risks
to the Company. The Company may be adversely affected by data breaches at retailers and other third parties who
maintain data relating to the Company’s customers that involve the theft of customer data, including the theft of
customers’ debit card, credit card, wire transfer and other identifying and/or access information used to make
purchases or payments at such retailers and to other third parties. Despite third-party security risks that are beyond the
Company’s control, the Company offers its customers protection against fraud and attendant losses for unauthorized
use of debit and credit cards in order to stay competitive in the marketplace. Offering such protection to customers
exposes the Company to significant expenses and potential losses related to reimbursing the Company’s customers
for fraud losses, reissuing the compromised cards and increased monitoring for suspicious activity. If a data breach of
considerable magnitude were to occur at one or more retailers, the Company’s business, financial condition and results
of operations may be adversely affected.

The Company’s risk management framework may not be effective in identifying, managing or mitigating risks
and/or losses to it.

The Company has implemented a risk management framework to identify and manage its risk exposure, which
is reviewed and overseen by the Company’s Risk Committee. This framework consists of various processes, systems
and strategies, and is designed to manage the types of risk to which the Company is subject, including, among others,
credit, market, liquidity, operational, financial, interest rate, legal and regulatory, compliance, strategic, reputation,
fiduciary and general economic risks. The Company’s framework also includes financial or other modeling
methodologies, which involves management assumptions and judgment. In addition, under this framework, the
Company has developed a risk appetite statement to detail its risk tolerance levels at an enterprise-wide level. This
risk management framework may not be effective under all circumstances, and it may not adequately identify, manage
or mitigate all or any risk or loss to the Company. If this framework is not effective, the Company may be subject to
potentially adverse regulatory consequences and could suffer unexpected losses and its financial condition or results
of operations could be materially adversely affected.

The Company is subject to risk arising from the failure or circumvention of internal controls and procedures.

The Company’s internal controls, including fraud detection and controls, disclosure controls and procedures,
and corporate governance procedures are based in part on certain assumptions and can provide only reasonable, not
absolute, assurances that the objectives of the controls and procedures are met. Any failure or circumvention of
controls and procedures; failure to comply with regulations related to controls and procedures; or failure to comply
with corporate governance procedures could have a material adverse effect on the Company’s reputation, business,
financial condition and results of operations, including subjecting us to litigation, regulatory fines, penalties or other
sanctions. Furthermore, notwithstanding the proliferation of technology and technology-based risk and control
systems, the Company’s business ultimately relies on people as its greatest resource, and the Company is subject to
the risk that they make mistakes or engage in violations of applicable policies, laws, rules or procedures that in the
past have not, and in the future may not always be prevented by the Company’s technological processes or by the
controls and other procedures intended to prevent and detect such errors or violations. Human errors, malfeasance and
other misconduct, even if promptly discovered and remediated, can result in reputational damage or legal risk and
have a material adverse effect on the Company’s business, financial condition and results of operations.

Legal, Regulatory and Compliance Risks

The Company operates in a highly regulated environment and, as a result, is subject to extensive regulation and
supervision.

The Company and the Bank are subject to extensive federal and state regulation and supervision. Banking
regulations are primarily intended to protect depositors’ funds, federal deposit insurance funds and the banking system
as a whole, not the Company’s shareholders. These regulations affect the Company’s lending practices, capital
structure, investment practices, dividend policy and growth, among other things. Congress and federal regulatory
agencies continually review banking laws, regulations and policies for possible changes. Any change in applicable
regulations or federal or state legislation could have a substantial impact on the Company, the Bank and their
respective operations.

29

The Dodd-Frank Act, enacted in July 2010, instituted major changes to the banking and financial institutions
regulatory regimes in light of the performance of and government intervention in the financial services sector during
the several years prior to the implementation of such Act. Additional legislation and regulations or regulatory policies
and other changes in interpretation or implementation of statutes, regulations or policies, could significantly affect the
Company’s powers, authority and operations, or the powers, authority and operations of the Bank in substantial and
unpredictable ways. Further, regulators have significant discretion and power to prevent or remedy unsafe or unsound
practices or violations of laws by banks and bank holding companies in the performance of their supervisory and
enforcement duties. Government authorities, including the bank regulatory agencies, are pursuing aggressive
enforcement actions with respect to compliance and other legal matters involving financial activities, which heightens
the risks associated with actual and perceived compliance failures. The exercise of this regulatory discretion and power
could have a negative impact on the Company. Further, failure to comply with laws, regulations or policies could
result in sanctions by regulatory agencies, civil money penalties and/or reputation damage. In some instances,
directives issued to enforce such actions may be confidential and thus, in those instances, the Company would not be
permitted to publicly disclose these actions. Any of the foregoing could have a material adverse effect on the
Company’s business, financial condition and results of operations.

In addition, the Company expects increased regulatory scrutiny during routine examinations and otherwise, and
new regulations adopted in response to recent negative developments in the banking industry, which may increase the
Company’s cost of doing business and reduce its profitability. Among other actions, there may be increased attention
by both regulators and investors on deposit composition, the amount of uninsured deposits, brokered deposits,
unrealized losses in securities portfolios, liquidity, commercial real estate loan composition and concentrations, and
capital, as well as the Company’s general oversight and control of such matters. The Company could face increased
scrutiny or be viewed as higher risk by regulators or investors, which could have a material adverse effect on the
Company’s business, financial condition, and results of operations.

The Company is subject to claims and litigation pertaining to intellectual property.

Banking and other financial services companies, such as the Company, rely on technology companies to provide
information technology products and services necessary to support
their day-to-day operations. Technology
companies frequently enter into litigation based on allegations of patent infringement or other violations of intellectual
property rights. In addition, patent holding companies seek to monetize patents they have purchased or otherwise
obtained. Competitors of the Company, the Company’s vendors, or other individuals or companies, have from time
to time claimed to hold intellectual property sold to the Company by its vendors. Such claims may increase in the
future as the financial services sector becomes more reliant on information technology vendors. The plaintiffs in these
actions frequently seek injunctions and substantial damages.

Regardless of the scope or validity of such patents or other intellectual property rights, or the merits of any
claims by potential or actual litigants, the Company may have to engage in protracted litigation. Such litigation is
often expensive, time-consuming, disruptive to the Company’s operations and distracting to management. If the
Company were found to have infringed one or more patents or other intellectual property rights, it may be required to
pay substantial damages or royalties to a third-party. In certain cases, the Company may consider entering into
licensing agreements for disputed intellectual property, although no assurance can be given that such licenses can be
obtained on acceptable terms or that litigation will not occur. These licenses may also significantly increase the
Company’s operating expenses. If legal matters related to intellectual property claims were resolved against the
Company or settled, the Company could be required to make payments in amounts that could have a material adverse
effect on its business, financial condition and results of operations.

The Company is subject to claims and litigation pertaining to fiduciary responsibility.

From time to time, customers make claims and take legal action pertaining to the Company’s performance of
its fiduciary responsibilities. Whether customer claims and legal action related to the Company’s performance of its
fiduciary responsibilities are founded or unfounded, if such claims and legal actions are not resolved in a manner
favorable to the Company, they may result in significant financial liability, adversely affect the market perception of
the Company and its products and services and/or impact customer demand for those products and services. Any
financial liability or reputation damage could have a material adverse effect on the Company’s business, financial
condition and results of operations.

30

Environmental, Social and Governance Risks

Severe weather, natural disasters and other adverse external climate events could significantly impact the
Company’s business and customers.

A significant portion of the Company’s business is generated from markets that have been, and may continue
to be, damaged by hurricanes, floods, tropical storms, tornadoes and other natural disasters and adverse weather, which
may grow more severe and could have a significant impact on the Company’s ability to conduct business. In addition,
such events could affect the stability of the Company’s deposit base, impair the ability of borrowers to repay
outstanding loans, impair the value of collateral securing loans, cause significant property damage, result in loss of
revenue and/or cause the Company to incur additional expenses. Furthermore, the occurrence of any such event in the
future could have a material adverse effect on the Company’s business, which, in turn, could have a material adverse
effect on the Company’s financial condition and results of operations.

Climate change could have a material negative impact on the Company and its customers

The Company’s business, as well as the operations and activities of its customers, could be negatively impacted
by climate change. Climate change presents both immediate and long-term risks to the Company and its customers
and these risks are expected to increase over time. These risks include (i) operational risk from the physical effects of
climate events on the Company’s facilities and other assets as well as those of customers; (ii) credit risk from
borrowers with significant exposure to climate risk; and (iii) reputational risk from stakeholder concerns about the
Company’s practices related to climate change, the Company’s carbon footprint and the Company’s business
relationships with customers who operate in carbon-intensive industries. The Company’s business, reputation and
ability to attract and retain employees may also be harmed if its response to climate change is perceived to be
ineffective or insufficient.

Climate change exposes the Company to physical risk as its effects may lead to more frequent and more extreme
weather events, such as prolonged droughts or flooding, tornadoes, hurricanes, wildfires and extreme seasonal
weather; and longer-term shifts, such as increasing average temperatures, ozone depletion and rising sea levels. Such
events and long-term shifts may damage, destroy or otherwise impact the value or productivity of the Company’s
properties and other assets; reduce the availability or increase the cost of insurance; and/or disrupt the Company’s
operations and other activities through prolonged outages. Such events and long-term shifts may also have a significant
impact on the Company’s customers, which could amplify credit risk by diminishing borrowers’ repayment capacity
or collateral values, and other businesses counterparties of the Company, which could have a broader impact on the
economy, supply chains and distribution networks.

Climate change also exposes the Company to risks associated with the transition to a less carbon-dependent
economy. These transition risks may result from changes in policies, laws and regulations, technologies, and/or market
preferences to address climate change. Such changes could have a material adverse effect on the Company’s business,
results of operations, financial condition and/or reputation, in addition to having a similar impact on the Company’s
customers. The Company has customers who operate in carbon-intensive industries, such as the oil and gas industry,
that are exposed to risks related to the transition to a less carbon-dependent economy, as well as customers who operate
in low-carbon industries that may be subject to risks associated with new technologies.

Increasing scrutiny and evolving expectations from customers, regulators, investors, and other stakeholders with
respect to the Company’s environmental, social and governance practices may impose additional costs on the
Company or expose it to new or additional risks.

Banking regulators and supervisory authorities, investors and other stakeholders have increasingly viewed
financial institutions as important in helping to address the risks related to climate change both directly and with
respect to their customers, which may result in financial institutions coming under increased pressure regarding the
disclosure and management of their climate risks and related lending and investment activities. Given that climate
change could impose systemic risks upon the financial sector, either via disruptions in economic activity resulting
from the physical impacts of climate change or changes in policies as the economy transitions to a less carbon-
intensive environment, the Company faces regulatory risk of increasing focus on its resilience to climate-related risks,
including in the context of stress testing for various climate stress scenarios. Ongoing legislative or regulatory
uncertainties and changes regarding climate risk management and practices may result in higher regulatory,
compliance, credit and reputational risks and costs.

Risks Associated with the Company’s Common Stock

The Company’s corporate organizational documents and the provisions of Texas law to which it is subject may
delay or prevent a change in control of the Company that a shareholder may favor.

The Company’s amended and restated articles of incorporation and amended and restated bylaws contain
various provisions which may delay, discourage or prevent an attempted acquisition or change of control of the
Company. These provisions include:

•

•

•

a Board of Directors classified into three classes of directors with the directors of each class having
staggered three-year terms;

a provision that any special meeting of the Company’s shareholders may be called only by the chairman
of the board and chief executive officer, the president, a majority of the Board of Directors or the holders
of at least 50% of the Company’s shares entitled to vote at the meeting; and

a provision establishing certain advance notice procedures for nomination of candidates for election as
directors and for shareholder proposals to be considered at an annual or special meeting of shareholders.

The Company’s articles of incorporation provide for noncumulative voting for directors and authorize the Board
of Directors to issue shares of its preferred stock without shareholder approval and upon such terms as the Board of
Directors may determine. The issuance of the Company’s preferred stock could have the effect of making it more
difficult for a third party to acquire, or of discouraging a third party from acquiring, a controlling interest in the
Company. In addition, certain provisions of Texas law, including a provision which restricts certain business
combinations between a Texas corporation and certain affiliated shareholders, may delay, discourage or prevent an
attempted acquisition or change in control of the Company.

There are restrictions on the Company’s ability to pay dividends.

Holders of the Company’s common stock are only entitled to receive such dividends as the Company’s Board
of Directors may declare out of funds legally available for such payments. Although the Company has historically
declared cash dividends on its common stock, it is not required to do so and there can be no assurance that the Company
will pay dividends in the future. Any declaration and payment of dividends on common stock will depend upon the
Company’s earnings and financial condition, liquidity and capital requirements, the general economic and regulatory
climate, the Company’s ability to service any equity or debt obligations senior to the common stock and other factors
deemed relevant by the Board of Directors.

The Company’s principal source of funds to pay dividends on the shares of common stock is cash dividends
that the Company receives from the Bank. Various banking laws applicable to the Bank limit the payment of dividends
and other distributions by the Bank to the Company, and may therefore limit the Company’s ability to pay dividends
on its common stock.

There may be substantial fluctuations in the Company’s stock price.

The trading price for the Company’s common stock may fluctuate significantly in response to a variety of

factors outside the Company’s control, including, among other things:

•

•

•

•

•

•

•

•

actual or anticipated variations in quarterly results of operations;

changes in recommendations by securities analysts;

failure to meet analysts’ revenue or earnings estimates;

changes in ratings from national rating agencies on the securities in the Company’s investment portfolio;

operating and stock price performance of other companies that investors deem comparable to the Company;

news reports relating to trends, concerns and other issues in the financial services industry;

perceptions in the marketplace regarding the Company and/or its competitors;

new technology used, or services offered, by competitors;

32

•

•

•

•

•

•

•

•

cybersecurity breaches;

actions by institutional shareholders;

significant acquisitions or business combinations, strategic partnerships,
commitments by or involving the Company or its competitors;

joint ventures or capital

failure to integrate acquisitions or realize anticipated benefits from acquisitions;

changes in government regulations;

geopolitical conditions such as acts or threats of terrorism or military conflicts, such as the wars in Ukraine
and the Middle East;

general market conditions, including real or anticipated changes in the strength of the Texas and Oklahoma
economies; and

industry factors and general economic and political conditions and events, such as economic slowdowns or
recessions, presidential and congressional elections, interest rate changes, oil price volatility or credit losses.

General Risks

Negative publicity could damage the Company’s reputation and business.

Reputation risk, or the risk to earnings and capital from negative public opinion, is inherent in the Company’s
business. Negative public opinion could result from the Company’s actual or alleged conduct in any number of
activities, including lending practices, corporate governance, regulatory compliance, mergers and acquisitions, and
disclosure, sharing or inadequate protection of customer information, and from actions taken by government regulators
and community organizations in response to that conduct. Negative public opinion could also result from adverse
news or publicity that impairs the reputation of the financial services industry generally. Negative public opinion could
adversely affect the Company’s ability to keep and attract customers and expose it to adverse legal and regulatory
consequences.

Public companies face increasing public scrutiny related to environmental, social and governance ("ESG")
activities. For example, in March 2022, the SEC issued a proposed rule on the enhancement and standardization of
climate-related disclosures for investors. The proposed rule would require public issuers, including the Company, to
significantly expand the scope of climate-related disclosures in their SEC filings. The SEC has also announced plans
to propose rules to require enhanced disclosure regarding human capital management and board diversity for public
issuers. The Company risks damage to its brand and reputation if it fails to act responsibly in a number of areas, such
as human capital management, support for local communities, corporate governance and transparency and
environmental stewardship, or fails to consider ESG factors in its business operations. Additionally, investors and
shareholder advocates are placing ever increasing emphasis on how corporations address ESG issues in their business
strategy when making investment decisions and when developing their proxy recommendations. The Company may
incur meaningful costs with respect to its ESG efforts and if such efforts are negatively perceived, the Company’s
reputation and stock price may suffer.

Failure to compete effectively for customers could adversely affect the Company’s growth and profitability, which
could have a material adverse effect on the Company’s business, financial condition and results of operations.

The Company faces substantial competition in all areas of its operations from a variety of different competitors,
many of which are larger and may have more financial resources. These competitors primarily include national,
regional, and community banks within the various markets where the Company operates. The Company also faces
competition from many other types of financial institutions, including savings and loans, credit unions, finance
companies, brokerage firms, insurance companies, financial technology (fintech) companies and other financial
intermediaries. The financial services industry could become even more competitive as a result of legislative,
regulatory and technological changes and continued consolidation. Also, technology and other changes have lowered
barriers to entry and made it possible for non-banks to offer products and services functionally equivalent to those
provided by banks. In addition, the emergence, adoption and evolution of new technologies that do not require
intermediation, including distributed ledgers such as digital assets and blockchain, as well as advances in robotic

33

process automation, could significantly affect the competition for financial services. The process of eliminating banks
as intermediaries, known as “disintermediation,” could result in the loss of fee income, as well as the loss of customer
deposits and the related income generated from those deposits. Further, many of the Company’s competitors have
fewer regulatory constraints and may have lower cost structures. Additionally, due to their size, many competitors
may be able to achieve economies of scale and, as a result, may offer a broader range of products and services as well
as better pricing for those products and services than the Company can. Failure to compete effectively for deposit,
loan and other banking customers in the Company’s market areas could adversely affect the Company’s growth and
profitability, which, in turn, could have a material adverse effect on the Company’s business, financial condition and
results of operations.

The Company may be adversely affected by the soundness of other financial institutions.

Financial services institutions are interrelated as a result of trading, clearing, counterparty or other relationships.
The Company has exposure to many different industries and counterparties, and routinely executes transactions with
counterparties in the financial services industry, including commercial banks, brokers and dealers, investment banks
and other institutional clients. Many of these transactions expose the Company to credit risk in the event of a default
by a counterparty or client. In addition, the Company’s credit risk may be exacerbated when the collateral held by the
Company cannot be realized upon or is liquidated at prices not sufficient to recover the full amount of the credit or
derivative exposure due to the Company. Any such losses could have a material adverse effect on the Company’s
financial condition, results of operations and cash flows.

New lines of business or new products and services may subject the Company to additional risks.

From time to time, the Company may implement or acquire new lines of business or offer new products and
services within existing lines of business. There are substantial risks and uncertainties associated with these efforts,
particularly in instances where the markets are not fully developed. In developing and marketing new lines of business
and/or new products and services, the Company may invest significant time and resources. Initial timetables for the
introduction and development of new lines of business and/or new products or services may not be achieved and price
and profitability targets may not prove feasible. External factors, such as compliance with regulations, competitive
alternatives and shifting market preferences, may also impact the successful implementation of a new line of business
or a new product or service. Furthermore, any new line of business and/or new product or service could have a
significant impact on the effectiveness of the Company’s system of internal controls. Failure to successfully manage
these risks in the development and implementation of new lines of business or new products or services could have a
material adverse effect on the Company’s business, financial condition and results of operations.

ITEM 1C. CYBERSECURITY

Risk Management and Strategy

The Company’s risk management program is designed to identify, assess, and mitigate risks across various
areas and functions, including financial, operational, technological, regulatory, reputational, and legal. Cybersecurity
is a critical component of this program, given the increasing reliance on technology and potential of cyber threats. The
Company’s Chief Information Security Officer is primarily responsible for this cybersecurity component and is a key
member of the risk management organization, reporting directly to the Chief Risk Officer and as discussed below,
periodically to the Strategic Technology Committee of the Bank’s board of directors.

The Company’s objective for managing cybersecurity risk is to avoid or minimize the impacts of external threat
events or other efforts to penetrate, disrupt or misuse its systems or information. The structure of the Company’s
information security program is designed around the National Institute of Standards and Technology Cybersecurity
Framework, regulatory guidance, and other industry standards. In addition, the Company leverages certain industry
and government associations, third-party benchmarking, audits, and threat intelligence feeds to facilitate and promote
program effectiveness. The Chief Information Security Officer and Chief Information Officer, who reports directly to

34

the Director of Corporate Strategy, along with key members of their teams, regularly collaborate with peer banks and
industry groups to discuss cybersecurity trends and issues and identify best practices. The information security
program is periodically reviewed by such personnel with the goal of addressing changing threats and conditions.

The Company employs an in-depth, layered, defensive strategy that embraces a “trust by design” philosophy
when designing new products, services, and technology. The Company leverages people, processes, and technology
as part of its efforts to manage and maintain cybersecurity controls. It also employs a variety of preventative and
detective tools designed to monitor, block, and provide alerts regarding suspicious activity, as well as to report on
suspected advanced persistent threats. The Company has established processes and systems designed to mitigate cyber
risk, including regular and on-going education and training for employees, preparedness simulations and tabletop
exercises, and recovery and resilience tests. It engages in regular assessments of its infrastructure, software systems,
and network architecture, using internal cybersecurity experts and third-party specialists. The Company also maintains
a third-party risk management program designed to identify, assess, and manage risks, including cybersecurity risks,
associated with external service providers and its supply chain. The Company also actively monitors its email
gateways for malicious phishing email campaigns and monitors remote connections as a portion of its workforce has
the option to work remotely. The Company leverages internal and external auditors and independent external partners
to periodically review its processes, systems, and controls, including with respect to its information security program,
to assess their design and operating effectiveness and make recommendations to strengthen its risk management
program.

The Company maintains an Information Security Incident Response Policy (“Incident Response Policy”) and
related procedures that provide a documented framework for responding to actual or potential cybersecurity incidents,
including timely notification of and escalation to the Crisis Management Team and to the appropriate regulatory and
governmental authorities. As needed, the notification may include the CEO and/or the Company’s and Bank’s Board
of Directors. The Incident Response Policy and procedures are coordinated through the Chief Risk Officer and key
members of management are embedded into the procedures by their design. The Incident Response Policy facilitates
coordination across multiple parts of the organization and is evaluated at least annually.

Notwithstanding the Company’s defensive measures and processes, the threat posed by cyber-attacks is severe.
The Company’s internal systems, processes, and controls are designed to mitigate loss from cyber-attacks and, while
it has experienced cybersecurity incidents in the past, to date, risks from cybersecurity threats have not materially
affected the Company. For further discussion of risks from cybersecurity threats, see the section captioned “An
interruption in or breach in security of the Company’s information systems may result in a loss of customer business
and have an adverse effect on the Company’s results of operations, financial condition and cash flows” in Item 1A.
Risk Factors.

Governance

The Chief Information Security Officer is accountable for managing the enterprise information security
include
department and delivering the information security program. The responsibilities of this department
cybersecurity risk assessment, a portion of defense operations, incident response, vulnerability assessment, threat
intelligence, identity access governance and third-party risk management. The Company’s information technology
department works together with information security in defense operations and is responsible for business resilience.
The foregoing responsibilities are covered on a day-to-day basis by a first line of defense function, and the Company’s
second line of defense function, including the Chief Information Security Officer, provides guidance, oversight,
monitoring and challenge of the first line’s activities. The second line of defense function is separated from the first
line of defense function through organizational structure and ultimately reports directly to the Chief Risk Officer. The
department consists of information security professionals with varying degrees of education and experience.
Individuals within the department are generally subject to professional education and certification requirements. The
Company’s Chief Information Security Officer has substantial relevant expertise and formal training in the areas of
information security and cybersecurity risk management.

The Bank’s board of directors has approved the management level Operations Committee, which focuses on
business impact, and the Enterprise Risk Management Committee (“ERM Committee”), which also focuses on
business impact and provides oversight and governance of the information security program, and the board level
Strategic Technology Oversight Committee (“STOC”), which focuses on technology impact and provides oversight

35

and governance of the technology program. The Operations Committee is chaired by the Chief Operating Officer and
includes the Chief Information Security Officer and Chief Information Officer and other key departmental managers
from throughout the Company. This committee generally meets bi-weekly to discuss various operational strategy and
issues, including information technology and information security policies, practices, controls, and mitigation and
prevention efforts.

The ERM Committee meets quarterly and oversees the information security program. It approves the broad
objectives, strategies and major policies governing the Company’s protection of data assets and provides agreement
on the definition and scope of the information security framework. Along with reviewing, approving, and prioritizing
information security efforts,

practices. From an enterprise perspective, the ERM Committee reviews the cybersecurity risk profile on a quarterly
basis and reports on cyber risk to the Risk Committee of the Company’s board of directors.

reviews and challenges the results and adequacy of

it

STOC is responsible for overseeing the Company’s technology program, including management’s actions to
identify, assess, mitigate, and remediate or prevent material cybersecurity issues and risks. The Company’s Chief
Information Security Officer and its Chief Information Officer provide quarterly reports to the STOC regarding the
information security program and the technology program, key enterprise cybersecurity initiatives, and other matters
relating to cybersecurity processes. The Chief Information Security Officer also reports summaries of key issues,
including significant cybersecurity and/or privacy incidents.

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED SHAREHOLDER MATTERS
AND ISSUER PURCHASES OF EQUITY SECURITIES

Common Stock Information

The Company’s common stock is listed on the New York Stock Exchange under the symbol “PB.” As of
February 26, 2024, there were 93,529,541 shares outstanding and 4,710 shareholders of record. The number of
beneficial owners is unknown to the Company at this time.

Dividends

Holders of common stock are entitled to receive dividends when, as and if declared by the Company’s Board of
Directors out of funds legally available therefor. Although the Company has declared dividends on its common stock
since 1994, and paid quarterly dividends aggregating $2.21 per share for 2023 and $2.11 per share for 2022, the
Company could discontinue payment of dividends in the future. Future dividends on the common stock will depend
upon the Company’s earnings and financial condition, liquidity and capital requirements, the general economic and
regulatory climate, the Company’s ability to service any equity or debt obligations senior to the common stock and
other factors deemed relevant by the Board of Directors of the Company.

As a holding company, the Company is ultimately dependent upon its subsidiaries to provide funding for its
operating expenses, debt service and dividends. Various banking laws applicable to the Bank limit the payment of
dividends and other distributions by the Bank to the Company and may therefore limit the Company’s ability to pay
dividends on its common stock. Regulatory authorities could impose administratively stricter limitations on the ability
of the Bank to pay dividends to the Company if such limits were deemed appropriate to preserve certain capital
adequacy requirements.

In addition, the Federal Reserve Board has indicated that bank holding companies should carefully review their
dividend policy in relation to the organization’s overall asset quality, level of current and prospective earnings and
level, composition and quality of capital. The guidance provides that the Company should inform and consult with the
Federal Reserve Board prior to declaring and paying a dividend that exceeds earnings for the period for which the
dividend is being paid or that could result in an adverse change to the Company’s capital structure.

The cash dividends declared per share by quarter (and paid on the first business day of the subsequent quarter)

for the Company’s last two fiscal years were as follows:

elements of the Company’s balance sheets and statements of income. This section should be read in conjunction with
the Company’s consolidated financial statements and accompanying notes and other detailed information appearing
elsewhere in this Annual Report on Form 10-K.

Overview

The Company generates the majority of its revenues from interest income on loans, service charges and fees on
customer accounts and income from investment in securities. The Company also earns revenues from various
additional products and services it provides, including trust services, mortgage lending, brokerage, credit card and
independent sales organization sponsorship operations. The Company’s revenues are partially offset by interest
expense paid on deposits and other borrowings and noninterest expenses such as administrative and occupancy
expenses. Net interest income is the difference between interest income on earning assets such as loans and securities
and interest expense on liabilities such as deposits and borrowings which are used to fund those assets. Net interest
income is the Company’s largest source of revenue. The level of interest rates and the volume and mix of earning
assets and interest-bearing liabilities impact net interest income and margin.

Three principal components of the Company’s growth strategy are internal growth, efficient operations and
acquisitions, including strategic merger transactions. The Company focuses on continual internal growth. Each
banking center is operated as a separate profit center, maintaining separate data with respect to its net interest income,
efficiency ratio, deposit growth, loan growth and overall profitability. The Company also focuses on maintaining
efficiency and stringent cost control practices and policies. The Company has centralized many of its critical
operations, such as data processing and loan and deposit processing. Management believes that this centralized
infrastructure can accommodate substantial additional growth while enabling the Company to minimize operational
costs through certain economies of scale. The Company also intends to continue to seek expansion opportunities. On
May 1, 2023, the Company acquired First Bancshares, as described under “—Recent Acquisition” below. On October
11, 2022, the Company announced the signing of a definitive merger agreement with Lone Star, as described under
“—Pending Acquisition” below.

Net income was $419.3 million, $524.5 million and $519.3 million for the years ended December 31, 2023,
2022 and 2021, respectively, and diluted earnings per share were $4.51, $5.73 and $5.60, respectively, for these same
periods. The change in net income and earnings per diluted share for the year ended December 31, 2023 was primarily
due to lower net interest income, the FDIC special assessment of $19.9 million, merger related provision for credit
losses of $18.5 million, merger related expenses of $15.1 million and additional expenses related to the merger of First
Bancshares. During the fourth quarter of 2023, Prosperity accrued for the FDIC special assessment of $19.9 million,
which was imposed by the FDIC to recover the cost associated with protecting uninsured depositors following the
closures of Silicon Valley Bank and Signature Bank in early 2023. The increase in net income and earnings per diluted
share for the year ended December 31, 2022 was primarily due to an increase in average balances and average rates
on investment securities, partially offset by a decrease in PPP fees and interest income of $44.6 million, a decrease in
loan discount accretion of $31.9 million and an increase in the average rates on interest-bearing liabilities.

The Company posted returns on average assets of 1.08%, 1.39% and 1.44% and returns on average common
equity of 6.03%, 7.97% and 8.21% for the years ended December 31, 2023, 2022 and 2021, respectively. The
Company’s efficiency ratio was 50.26% in 2023, 42.23% in 2022 and 41.83% in 2021. The efficiency ratio is
calculated by dividing total noninterest expense (excluding net gains and losses on the sale or write down of assets
and securities) by the sum of net interest income and noninterest income. Because the ratio is a measure of revenues
and expenses resulting from the Company’s lending activities and fee-based banking services, net gains and losses on
the sale of assets and securities are not included. Additionally, taxes are not part of this calculation.

43

Total assets at December 31, 2023 and 2022 were $38.55 billion and $37.69 billion, respectively. Total deposits
were $27.18 billion at December 31, 2023, a decrease of $1.35 billion or 4.7% compared with $28.53 billion at
December 31, 2022. Total loans were $21.18 billion at December 31, 2023, an increase of $2.34 billion or 12.4%
compared with $18.84 billion at December 31, 2022. At December 31, 2023, the Company had $70.9 million in
nonperforming loans, and its allowance for credit losses on loans was $332.4 million compared with $25.5 million in
nonperforming loans and an allowance for credit losses on loans of $281.6 million at December 31, 2022.
Shareholders’ equity was $7.08 billion and $6.70 billion at December 31, 2023 and 2022, respectively.

Recent Acquisition

Merger of First Bancshares of Texas, Inc. — Effective May 1, 2023, the Company completed the merger of
First Bancshares into the Company and the subsequent merger of its wholly owned subsidiary, FirstCapital Bank, into
the Bank (collectively, the “Merger”). FirstCapital Bank operated 16 full-service banking offices in six different
markets in West, North and Central Texas areas, including its main office in Midland, Texas and banking offices in
Midland, Lubbock, Amarillo, Wichita Falls, Burkburnett, Byers, Henrietta, Dallas, Horseshoe Bay, Marble Falls and
Fredericksburg, Texas. As of March 31, 2023, First Bancshares, on a consolidated basis, reported total assets of $2.14
billion, total loans of $1.65 billion and total deposits of $1.71 billion.

Pursuant to the terms of the definitive agreement, the Company issued 3,583,370 shares of its common stock
and approximately $91.5 million in cash for all outstanding shares of First Bancshares capital stock. As of December
31, 2023, the Company recognized goodwill of $164.5 million which does not include all the subsequent fair value
adjustments that have not yet been finalized. During the second quarter of 2023, the Company completed the
operational conversion of FirstCapital Bank.

Pending Acquisition

Pending Acquisition of Lone Star State Bancshares, Inc. — On October 11, 2022, the Company and Lone Star
jointly announced the signing of a definitive merger agreement whereby Lone Star, the parent company of Lone Star
State Bank, will merge with and into the Company. Lone Star Bank operates five banking offices in the West Texas
area, including its main office in Lubbock, and one banking center in each of Brownfield, Midland, Odessa and Big
Spring, Texas. As of December 31, 2023, Lone Star, on a consolidated basis, reported total assets of $1.37 billion,
total loans of $1.08 billion and total deposits of $1.21 billion.

Under the terms of the definitive agreement, Bancshares will issue 2,376,182 shares of its common stock plus
$64.1 million in cash for all outstanding shares of Lone Star capital stock, subject to certain conditions and potential
adjustments. Based on the closing price of Bancshares' common stock of $69.27 on October 7, 2022, the total
consideration was valued at approximately $228.7 million. The transaction is subject to customary closing conditions,
including the receipt of regulatory approvals. The shareholders of Lone Star approved the transaction on March 28,
2023.

Critical Accounting Estimates

The preparation of financial statements in conformity with GAAP requires the Company to establish accounting
policies and make estimates that affect amounts reported in the consolidated financial statements. An accounting
estimate requires assumptions and judgments about uncertain matters that could have a material effect on the
consolidated financial statements. Estimates are made using facts and circumstances known at a point in time. Changes
in those facts and circumstances could produce results substantially different from those estimates. The Company’s
accounting policies are described in detail in Note 1 to the consolidated financial statements, appearing elsewhere in
this Annual Report on Form 10-K. The Company believes that of its significant accounting policies, the following
may involve a higher degree of judgment and complexity:

Business Combinations—Generally, acquisitions are accounted for under the acquisition method of accounting
in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”)
805, Business Combinations. A business combination occurs when the Company acquires net assets that constitute a
business and obtains control over that business. Business combinations are effected through the transfer of

44

consideration consisting of cash and/or common stock and are accounted for using the acquisition method.
Accordingly, the assets and liabilities of the acquired business are recorded at their respective fair values at the
acquisition date. Determining the fair value of assets and liabilities, especially the loan portfolio, is a process involving
significant judgment regarding methods and assumptions used to calculate estimated fair values. Fair values are
subject to refinement for up to one year after the closing date of the acquisition as information relative to closing date
fair values becomes available. The results of operations of an acquired entity are included in the Company’s
consolidated results from acquisition date, and prior periods are not restated.

Allowance for Credit Losses— The allowance for credit losses is accounted for in accordance with ASU 2016-
13, “Financial Instruments-Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments”
(“CECL”) which replaced the incurred loss methodology with an expected loss methodology that is referred to as the
current expected credit loss methodology. CECL requires a financial asset (or a group of financial assets) measured
at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is
an allowance available for losses on loans and held-to-maturity securities. The allowance for credit losses is adjusted
through charges to earnings in the form of a provision for credit losses. All losses are charged to the allowance when
the loss actually occurs or when a determination is made that such a loss is likely and can be reasonably estimated.
Recoveries are credited to the allowance at the time of recovery.

The Company’s allowance for credit losses consists of two elements: (1) specific valuation allowances based
on expected losses on impaired loans and certain purchased credit-deteriorated loans (“PCD”); and (2) a general
valuation allowance based on historical lifetime loan loss experience, current economic conditions, reasonable and
supportable forecasted economic conditions and other qualitative risk factors both internal and external to the
Company. Management has established an allowance for credit losses which it believes is adequate for estimated
losses in the Company’s loan portfolio. Based on an evaluation of the portfolio, management presents a quarterly
review of the allowance for credit losses to the Bank’s Board of Directors, indicating any change in the allowance
since the last review and any recommendations as to adjustments in the allowance. In making its evaluation,
management considers factors such as historical lifetime loan loss experience, the amount of nonperforming assets
and related collateral, the volume, growth and composition of the portfolio, current economic conditions and
reasonable and supportable forecasted economic conditions that may affect borrower ability to pay and the value of
collateral, the evaluation of the portfolio through its internal loan review process and other relevant factors. Portions
of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that,
in management’s judgment, should be charged off. Charge-offs occur when loans are deemed to be uncollectible.
Pursuant to the Company's adoption of ASU 2022-02 effective January 1, 2023, the Company prospectively
discontinued troubled debt restructurings accounting and no longer measures the economic concession for loan
modifications occurring on or after the adoption date. In addition, modifications to loans previously designated as
troubled debt restructurings that occur on or after January 1, 2023, are accounted for under the newly adopted ASU
and result in the elimination of any prior economic concession recorded in the allowance related to such loans. For
further discussion of the methodology used in the determination of the allowance for credit losses, see “Accounting
for Acquired Loans and the Allowance for Acquired Credit Losses”, “Financial Condition—Allowance for Credit
Losses” sections below and Note 1 to the consolidated financial statements.

Accounting for Acquired Loans and the Allowance for Acquired Credit Losses — The Company accounts for
its acquisitions using the acquisition method of accounting. Accordingly, the assets, including loans, and liabilities of
the acquired entity were recorded at their fair values at the acquisition date. These fair value estimates associated with
acquired loans, based on a discounted cash flow model, include estimates related to market interest rates and
undiscounted projections of future cash flows that incorporate expectations of prepayments and the amount and timing
of principal, interest and other cash flows, as well as any shortfalls thereof. For further discussion of the methodology
used in the determination of the allowance for credit losses for acquired loans, see “Accounting for Acquired Loans
and the Allowance for Acquired Credit Losses” in Note 1 to the consolidated financial statements and “Financial
Condition—Allowance for Credit Losses on Loans” below.

Goodwill and Intangible Assets—Goodwill and intangible assets that have indefinite useful lives are subject to
an impairment test at least annually, or more often, if events or circumstances indicate that it is more likely than not
that the fair value of the Company’s reporting unit is below the carrying value of its equity. Under ASC Topic 350-
20, “Intangibles—Goodwill and Other—Goodwill,” companies have the option to first assess qualitative factors to
determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a

45

basis for determining the need to perform step one of the annual test for goodwill impairment. An entity has an
unconditional option to bypass the qualitative assessment described in the following paragraph for any reporting unit
in any period and proceed directly to performing the first step of the goodwill impairment test. An entity may resume
performing the qualitative assessment in any subsequent period. If the estimated fair value of the reporting unit exceeds
its carrying value, goodwill of the reporting unit is not impaired.

The Company had no intangible assets with indefinite useful lives at December 31, 2023. Core deposit intangible
assets that are subject to amortization are being amortized on a non-pro rata basis over the years expected to be
benefited, which the Company believes is between ten and fifteen years. These core deposit intangible assets are
reviewed for impairment if circumstances indicate their value may not be recoverable based on a comparison of fair
value to carrying value. The Company performs an evaluation annually, and more frequently if a triggering event
occurs, of whether any impairment of the goodwill and other intangibles has occurred. Based on the Company’s annual
goodwill impairment test as of October 1, 2023, management does not believe any of its goodwill is impaired as of
December 31, 2023, because the fair value of the Company’s equity exceeded its carrying value. While the Company
believes no impairment existed at December 31, 2023, under accounting standards applicable at that date, different
conditions or assumptions, or changes in cash flows or profitability, if significantly negative or unfavorable, could
have a material adverse effect on the outcome of the Company’s impairment evaluation and financial condition or
future results of operations.

Results of Operations

Net Interest Income

The Company’s operating results depend primarily on its net interest income, which is the difference between
interest income on interest-earning assets, including securities and loans, and interest expense incurred on interest-
bearing liabilities, including deposits and other borrowed funds. Interest rate fluctuations, as well as changes in the
amount and type of earning assets and liabilities, combine to affect net interest income. The Company’s net interest
income is affected by changes in the amount and mix of interest-earning assets and interest-bearing liabilities, referred
to as a “volume change.” It is also affected by changes in yields earned on interest-earning assets and rates paid on
interest-bearing deposits and other borrowed funds, referred to as a “rate change.”

2023 versus 2022. Net interest income before the provision for credit losses for 2023 was $956.4 million
compared with $1.01 billion for 2022, a decrease of $48.8 million or 4.9%. The change was primarily due to an
increase in the average balances and average rates on other borrowings and an increase in the average rates on interest-
bearing deposits, partially offset by increases in the average balances and average rates on loans. Interest income was
$1.44 billion in 2023, an increase of $349.7 million or 31.9% compared with 2022. Interest income on loans was $1.15
billion for 2023, an increase of $317.8 million or 38.2% compared with 2022, primarily due an increase in the average
balances and average rates on loans. The Company had $27.9 million of total outstanding accretable discounts on
Non-PCD loans and PCD loans at December 31, 2023. Interest income on securities was $283.3 million during 2023,
an increase of $22.9 million or 8.8% compared with 2022 due primarily to an increase the average rates on investment
securities, partially offset by a decrease in the average balances on investment securities. Average interest-bearing
liabilities increased $1.50 billion or 7.5% during 2023 compared with 2022. The average rate on interest-bearing
liabilities increased from 0.45% to 2.27% during the same time period, resulting in an increase in interest expense of
$398.5 million. The total cost of funds increased to 1.54% during 2023 compared to 0.29% during 2022.

Net interest margin, defined as net interest income divided by average interest-earning assets, was 2.78% on a

tax equivalent basis for 2023, a decrease of 22 basis points compared with 3.00% for 2022.

2022 versus 2021. Net interest income before the provision for credit losses for 2022 was $1.01 billion compared
with $993.3 million for 2021, an increase of $11.9 million or 1.2%. The change was primarily due to an increase in
average balances and average rates on investment securities, partially offset by a decrease in PPP fees and interest
income of $44.6 million, a decrease in loan discount accretion of $31.9 million and an increase in the average rates
on interest-bearing liabilities. Interest income was $1.09 billion in 2022, an increase of $47.9 million or 4.6%
compared with 2021. Interest income on loans was $831.2 million for 2022, a decrease of $38.7 million or 4.5%
compared with 2021, primarily due to a decrease in PPP fees and interest income of $44.6 million and a decrease in
loan discount accretion of $31.9 million, partially offset by an increase in loan interest income for loans held for

46

investment. The Company had $5.6 million of total outstanding accretable discounts on Non-PCD loans and PCD
loans at December 31, 2022. Interest income on securities was $260.4 million during 2022, an increase of $85.0
million or 48.4% compared with 2021 due primarily to an increase in average balances and average rates on investment
securities. Average interest-bearing liabilities increased $625.4 million or 3.2% during 2022 compared with 2021. The
average rate on interest-bearing liabilities increased from 0.28% to 0.45% during the same time period, resulting in an
increase in interest expense of $36.0 million. The total cost of funds increased to 0.29% during 2022 compared to
0.18% during 2021.

Net interest margin was 3.00% on a tax equivalent basis for 2022, a decrease of 14 basis points compared with

3.14% for 2021.

The following table presents, for the periods indicated, the total dollar amount of average balances, interest
income from average interest-earning assets and the resultant yields, as well as the interest expense on average interest-
bearing liabilities, expressed both in dollars and rates. Except as indicated in the footnotes, no tax-equivalent
adjustments were made and all average balances are daily average balances. Any nonaccruing loans have been
included in the table as loans carrying a zero yield.

(1) The net interest margin is equal to net interest income divided by average interest-earning assets.
(2) In order to make pretax income and resultant yields on tax-exempt investments and loans comparable to those on
taxable investments and loans, a tax equivalent adjustment has been computed using a federal income tax rate of
21% and other applicable effective tax rates for the years ended December 31, 2023, 2022 and 2021.

The following table presents information regarding the dollar amount of changes in interest income and interest
expense for the periods indicated for each major component of interest-earning assets and interest-bearing liabilities
and distinguishes between the changes attributable to changes in volume and changes in interest rates. For purposes
of this table, changes in interest income and interest expense related to purchase accounting adjustments and changes
attributable to both rate and volume which cannot be segregated have been allocated to rate.

The Company’s provision for credit losses is established through charges to income to bring the Company’s
allowance for credit losses on loans and off-balance sheets credit exposures to a level deemed appropriate by
management based on the factors discussed under “Financial Condition—Allowance for Credit Losses” and
“Financial Condition—Allowance for Credit Losses on Off-Balance Sheet Credit Exposures” The allowance for
credit losses on loans at December 31, 2023 was $332.4 million, or 1.57% of total loans and 1.63% of total loans
excluding Warehouse Purchase Program loans. The allowance for credit losses on loans at December 31, 2022 was
$281.6 million, or 1.49% of total loans and 1.56% of total loans excluding Warehouse Purchase Program loans.
Acquired loans were recorded at fair value based on a discounted cash flow valuation methodology that considers,
among other things, interest rates, projected default rates, loss given defaults and recovery rates, with no carryover of
any existing allowance for credit losses. The allowance for credit losses on off-balance sheet credit exposures was
$36.5 million at December 31, 2023, compared to $29.9 million at December 31, 2022. The provision for credit losses
was $18.5 million for the year ended December 31, 2023, compared to no provision for credit losses for the years
ended December 31, 2022 and 2021. The $18.5 million provision was due to loans acquired in the Merger and included
a $12.0 million provision for credit losses on loans and a $6.5 million provision for credit losses on off-balance sheet
credit exposures.

Net charge-offs for the years ended December 31, 2023, 2022 and 2021 were $38.0 million, $4.8 million and
$29.7 million, respectively. Net charge-offs for the year ended December 31, 2023 included $16.6 million related to
resolved PCD loans and $15.0 million related to one commercial real estate loan acquired in a previous merger. The
PCD loans had reserves of $16.3 million assigned as of the acquisition date. Additionally, reserves on PCD loans
increased by $76.8 million due to the Merger and $23.5 million of reserves on resolved PCD loans was released to the
general reserve.

Noninterest Income

The Company’s primary sources of recurring noninterest income are credit, debit and ATM card income,
nonsufficient funds (“NSF”) fees, and service charges on deposit accounts. Additionally, the Company generates
recurring noninterest income from its various additional products and services, including trust services, mortgage
lending, brokerage and independent sales organization sponsorship operations. Noninterest income does not include
loan origination fees, which are recognized over the life of the related loan as an adjustment to yield using the interest
method. For the year ended December 31, 2023, noninterest income totaled $153.3 million, an increase of $8.1 million
or 5.6% compared with 2022. This increase was primarily due to the Merger, partially offset by lower net gain on the
sale or write-down of assets.

For the year ended December 31, 2022, noninterest income totaled $145.1 million, an increase of $5.2 million
or 3.7% compared with 2021. This increase was primarily due to an increase in NSF income, a net gain on the sale or
write-down of assets, an increase in trust income and an increase in other noninterest income, partially offset by a
decrease in mortgage income.

The following table presents, for the periods indicated, the major categories of noninterest income:

Noninterest Expense

For the year ended December 31, 2023, noninterest expense totaled $556.7 million, an increase of $72.5 million
or 15.0% compared with 2022. The change was primarily due to the FDIC special assessment of $19.9 million, merger
related expenses of $15.1 million and additional expenses related to the Merger.

For the year ended December 31, 2022, noninterest expense totaled $484.2 million, an increase of $10.6 million
or 2.2% compared with 2021. The change was primarily due to an increase in salaries and benefits, an increase in
credit and debit card and data processing expense and lower net gains on sale of other real estate.

(3) Other real estate expense is net of rental income and gains and losses on sales of real estate.

Salaries and Employee Benefits. Salaries and employee benefits were $328.4 million for the year ended
December 31, 2023, an increase of $13.7 million or 4.4% compared with 2022, as a result of the Merger. Salaries and
employee benefits were $314.7 million for the year ended December 31, 2022, an increase of $4.2 million or 1.3%
compared with 2021. The number of full-time equivalent associates employed by the Company was 3,850, 3,633 and
3,704 at December 31, 2023, 2022 and 2021, respectively. Total salaries and benefits for the year ended December
31, 2023 included $12.2 million in stock-based compensation expense compared with $11.8 million and $12.6 million
recorded for each of the years ended December 31, 2022 and 2021, respectively.

Net Occupancy and Equipment: Net occupancy and equipment expense was $35.5 million for the year ended
December 31, 2023, an increase of $3.1 million or 9.5% compared with 2022, primarily due to the Merger. Net
occupancy and equipment expense was $32.4 million for the year ended December 31, 2022, an increase of $262
thousand compared with 2021.

Credit and Debit Card, Data Processing and Software Amortization. Credit and debit card, data processing and
software amortization expenses were $41.6 million for the year ended December 31, 2023, an increase of $4.2 million
or 11.4% compared with 2022, primarily due to an increase in data processing costs and the Merger. Credit and debit
card, data processing and software amortization expenses were $37.3 million for the year ended December 31, 2022,
an increase of $2.2 million or 6.3% compared with 2021, as a result of increase in debit card interchange fees and
software maintenance expense.

Regulatory Assessments and FDIC Insurance. Regulatory assessments and FDIC insurance assessments were
$40.2 million for the year ended December 31, 2023, an increase of $28.8 million, compared with $11.4 million for
the year ended December 31, 2022, as a result of the FDIC special assessment of $19.9 million and the Merger. During
the fourth quarter of 2023, Prosperity accrued for the FDIC special assessment of $19.9 million, which was imposed
by the FDIC to recover the cost associated with protecting uninsured depositors following the closures of Silicon
Valley Bank and Signature Bank in early 2023. Regulatory assessments and FDIC insurance assessments were $11.4
million for the year ended December 31, 2022, an increase of $743 thousand or 7.0%, compared with $10.6 million
for the year ended December 31, 2021.

51

Core Deposit Intangibles Amortization. Core deposit intangibles (“CDI”) amortization was $12.7 million for
the year ended December 31, 2023, an increase of $2.3 million or 22.6% compared with $10.3 million for the year
ended December 31, 2022. CDI amortization was $10.3 million for the year ended December 31, 2022, a decrease of
$1.2 million or 10.5% compared with $11.6 million for the year ended December 31, 2021.

2023, a change of $712 thousand compared with $(122) thousand for the year ended December 31, 2022. Other real
estate (income) expense was $(122) thousand for the year ended December 31, 2022, a change of $2.1 million
compared with $(2.2) million for the year ended December 31, 2021, primarily due to a decrease in sales of other real
estate in 2022.

Merger Related Expenses. Merger related expenses were $15.1 million for the year ended December 31, 2023,
due to the Merger and the pending merger of Lone Star. Merger related expenses were $272 thousand for the year
ended December 31, 2022, due to the pending acquisitions of First Bancshares and Lone Star announced in October
2022.

Efficiency Ratio

The Company’s efficiency ratio is a supplemental financial measure utilized in management’s internal
evaluation of the Company and is not calculated based on GAAP. A GAAP-based efficiency ratio is calculated by
dividing total noninterest expense, excluding credit loss provisions, by net interest income plus total noninterest
income, as shown in the Consolidated Statements of Income. The Company’s efficiency ratio, as calculated and used
by the Company, excludes from noninterest income the net gains and losses on the sale of securities and assets, which
can vary widely from period to period. Taxes are not included in either calculation. The Company believes this non-
GAAP financial measure provides information useful to investors by excluding certain items that may not be indicative
of its core net operating earnings and business outlook. This non-GAAP financial measure should not be considered
a substitute for, nor of greater importance than, the GAAP basis financial measure. Because a non-GAAP financial
measure is not standardized, it may not be possible to compare this financial measure with other companies’ non-
GAAP financial measures having the same or a similar name. An increase in the efficiency ratio indicates that more
resources are being utilized to generate the same volume of income, while a decrease would indicate a more efficient
allocation of resources. The Company’s efficiency ratio calculated pursuant to GAAP was 50.17% for the year ended
December 31, 2023 compared with 42.09% for the year ended December 31, 2022 and 41.79% for the year ended
December 31, 2021. The efficiency ratio, excluding net gains and losses on the sale or write down of assets and taxes,
was 50.26% for the year ended December 31, 2023, compared with 42.23% for the year ended December 31, 2022
and 41.83% for the year ended December 31, 2021.

Income Taxes

The amount of federal and state income tax expense is influenced by the amount of pre-tax income, the amount
of tax-exempt income and the amount of nondeductible expenses. Income tax expense was $115.1 million for the year
ended December 31, 2023, a decrease of $26.5 million or 18.7% compared with $141.7 million for the year ended
December 31, 2022. Income tax expense was $141.7 million for the year ended December 31, 2022, an increase of
$1.3 million or 0.9% compared with $140.4 million for the year ended December 31, 2021. The effective tax rate for
the years ended December 31, 2023, 2022 and 2021 was 21.5%, 21.3% and 18.0%, respectively. The effective income
tax rates differed from the U.S. statutory rate of 21% during 2023, 2022 and 2021 primarily due to the effect of tax-
exempt income from loans and securities.

Impact of Inflation

The Company’s consolidated financial statements and related notes included in this Annual Report on Form 10-
K have been prepared in accordance with GAAP. These require the measurement of financial position and operating
results in terms of historical dollars, without considering changes in the relative value of money over time due to
inflation or recession.

52

Unlike many industrial companies, substantially all of the Company’s assets and liabilities are monetary in
nature. As a result, interest rates have a more significant impact on the Company’s performance than the effects of
general levels of inflation. Interest rates may not necessarily move in the same direction or in the same magnitude as
the prices of goods and services. However, noninterest expenses do reflect general levels of inflation.

The Company separates its loan portfolio into two general categories of loans: (1) “originated loans,” which are
loans originated by Prosperity Bank and made pursuant to the Company’s loan policy and procedures in effect at the
time the loan was made, and (2) “acquired loans,” which are loans acquired in a business combination and recorded
at fair value at the acquisition date. Those acquired loans that are renewed or substantially modified after the date of
the business combination are referred to as “re-underwritten acquired loans.” If a renewal or substantial modification
of an acquired loan is underwritten by the Company with a new credit analysis, the loan may no longer be categorized
as an acquired loan. For example, acquired loans to one borrower may be combined into a new loan with a new loan
number and categorized as an originated loan. Acquired loans with a fair value discount or premium at the date of the
business combination that remained at the reporting date are referred to as “fair-valued acquired loans.” All fair-valued
acquired loans are further categorized into “PCD Loans” and “Non-PCD loans.” Acquired loans with evidence of
more than insignificant credit quality deterioration as of the acquisition date when compared to the origination date
are classified as PCD loans.

The Company offers a broad range of short to medium-term commercial loans, primarily collateralized, to
businesses for working capital (including inventory and receivables), business expansion (including acquisitions of
real estate and improvements) and the purchase of equipment and machinery. Historically, the Company has originated
loans for its own account, including loans in the 1-4 family residential category, and has not securitized its loans.
However, the Company does originate longer-term residential mortgage loans for sale into the secondary market. The
purpose of a particular loan generally determines its structure.

Loans to borrowers with aggregate debt relationships over $1.0 million and below $5.0 million are evaluated
and acted upon on a daily basis by two of the company-wide loan concurrence officers. Loans to borrowers with
aggregate debt relationships above $5.0 million are evaluated and acted upon by an officers’ loan committee that
meets weekly.

54

Commercial and Industrial Loans. In nearly all cases, the Company’s commercial loans are made in the
Company’s market areas and are underwritten based on the borrower's ability to service the debt from income.
Working capital loans are primarily collateralized by short-term assets whereas term loans are primarily collateralized
by long-term assets. As a general practice, term loans are secured by any available real estate, equipment or other
assets owned by the borrower. Both working capital and term loans are typically supported by a personal guaranty of
a principal. In general, commercial loans involve more credit risk than residential mortgage loans and commercial
mortgage loans and, therefore, usually yield a higher return. The increased risk in commercial loans is due to the type
of collateral securing these loans as well as the expectation that commercial loans generally will be serviced principally
from the operations of the business, and those operations may not be successful. Historical trends have shown these
types of loans to have higher delinquencies than mortgage loans. As a result of these additional complexities, variables
and risks, commercial loans require more thorough underwriting and servicing than other types of loans.

Included in commercial loans are (1) commitments to oil and gas producers largely secured by proven,
developed and producing reserves and (2) commitments to service, equipment and midstream companies secured
mainly by accounts receivable, inventory and equipment. Mineral reserve values supporting commitments to
producers are normally re-determined semi-annually using reserve studies prepared by a third-party or the Company’s
oil and gas engineer. Accounts receivable and inventory borrowing bases for service companies are typically re-
determined monthly. Funding requests by both producers and service companies are monitored relative to the most
recently determined borrowing base. As of December 31, 2023, the Company had $80.3 million (net of discount and
excluding PPP loans totaling $2.0 million) in funded commitments outstanding to oil and gas production companies
and $303.1 million in unfunded commitments, for a total of $383.4 million. This compares with funded commitments
to oil and gas production companies of $209.0 million (net of discount and excluding PPP loans totaling $2.0 million)
and $357.4 million in unfunded commitments, for a total of $566.4 million as of December 31, 2022. Total unfunded
commitments to producers include letters of credit issued in lieu of oil well plugging bonds. As of December 31, 2023,
the Company had $288.1 million (net of discount and excluding PPP loans totaling $627 thousand) in funded
commitments outstanding to service companies and $168.5 million in unfunded commitments, for a total of $456.6
million. This compares with funded commitments to service companies of $220.5 million (net of discount and
excluding PPP loans totaling $1.4 million) and $95.9 million in unfunded commitments, for a total of $316.4 million
as of December 31, 2022.

Commercial Real Estate. The Company makes commercial real estate loans collateralized by owner-occupied
and nonowner-occupied real estate to finance the purchase of real estate. The Company’s commercial real estate loans
are collateralized by first liens on real estate, typically have variable interest rates (or five year or less fixed rates) and
amortize over a 15- to 25-year period. Payments on loans secured by nonowner-occupied properties are often
dependent on the successful operation or management of the properties. Accordingly, repayment of these loans may
be subject to adverse conditions in the real estate market or the economy to a greater extent than other types of loans.
The Company seeks to minimize these risks in a variety of ways, including giving careful consideration to the
property’s operating history, future operating projections, current and projected occupancy, location and physical
condition, in connection with underwriting these loans. The underwriting analysis also includes credit verification,
analysis of global cash flow, appraisals and a review of the financial condition of the borrower and guarantor. Loans
to hotels and restaurants are primarily included in commercial real estate loans.

1-4 Family Residential Loans. The Company’s lending activities also include the origination of 1-4 family
residential mortgage loans (including home equity loans) collateralized by owner-occupied and nonowner-occupied
residential properties located in the Company’s market areas. The Company offers a variety of mortgage loan portfolio
products which generally are amortized over five to 30 years. Loans collateralized by 1-4 family residential real estate
generally have been originated in amounts of no more than 89% of appraised value. The Company requires mortgage
title insurance, as well as hazard, wind and/or flood insurance as appropriate. The Company prefers to retain residential
mortgage loans for its own account rather than selling them into the secondary market. By doing so, the Company
incurs interest rate risk as well as the risks associated with non-payments on such loans. The Company’s mortgage
department also offers a variety of mortgage loan products which are generally amortized over 30 years, including
FHA and VA loans, which are sold to secondary market investors.

55

Construction, Land Development and Other Land Loans. The Company makes loans to finance the construction
of residential and nonresidential properties. Construction loans generally are collateralized by first liens on real estate
and have variable interest rates. The Company conducts periodic inspections, either directly or through an agent, prior
to approval of periodic draws on these loans. Underwriting guidelines similar to those described above are also used
in the Company’s construction lending activities, with heightened analysis of construction and/or development costs.
Construction loans involve additional risks attributable to the fact that loan funds are advanced upon the security of a
project under construction, and the project is of uncertain value prior to its completion. Because of uncertainties
inherent in estimating construction costs, the market value of the completed project and the effects of governmental
regulation on real property, it can be difficult to accurately evaluate the total funds required to complete a project and
the related loan to value ratio. As a result of these uncertainties, construction lending often involves the disbursement
of substantial funds with repayment dependent, in part, on the success of the ultimate project rather than the ability of
a borrower or guarantor to repay the loan. If the Company is forced to foreclose on a project prior to completion, the
Company may not be able to recover all of the unpaid portion of the loan. In addition, the Company may be required
to fund additional amounts to complete a project and may have to hold the property for an indeterminate period of
time. Although the Company has underwriting procedures designed to identify what it believes to be acceptable levels
of risks in construction lending, these procedures may not prevent losses from the risks described above.

Warehouse Purchase Program. The Warehouse Purchase Program allows unaffiliated mortgage originators
(“Clients”) to close 1-4 family real estate loans in their own name and manage their cash flow needs until the loans
are sold to investors. The Company's Clients are strategically targeted for their experienced management teams and
analyzed for the expected profitability of each Client’s business model over the long term. The Clients are located
across the U.S. and originate mortgage loans primarily through traditional retail and/or wholesale business models
using underwriting standards as required by United States government-sponsored enterprise agencies, “Agencies”
such as Fannie Mae, private investors to which the mortgage loans are ultimately sold and/or mortgage insurers.

At December 31, 2023, the Company had 33 mortgage banking company customers with aggregate uncommitted
facilities (“Facilities”) of $1.94 billion and an actual aggregate outstanding balance of $822.2 million; and the Clients’
individual Facilities ranged in size from $3.0 million to $200.0 million. A Facility is often supported by a payment
guaranty of
the Client’s owners holding significant ownership positions, along with non-interest-bearing
compensating balance deposits in line with the Facility amount. Typical covenants include minimum tangible net
worth, maximum leverage and minimum liquidity. As loans age, the Company requires loan curtailments to reduce
the Company’s risk if an individual mortgage loan is not timely purchased by an investor. The average mortgage loan
being purchased by the Company reflects a blend of Agency and private investor underwriting guidelines. At
December 31, 2023 the Company’s mortgage warehouse portfolio had an average loan-to-value ratio (LTV) of 77%,
an average credit score of 696 and an average loan size of $303 thousand. The Company’s purchases under these
Facilities are priced using a combined base rate and a risk premium set for both product type (Prime, Jumbo, etc.) and
age of the loan.

Although not subject to any legally binding commitment, when the Company makes a purchase decision, it
acquires a 100% participation interest in the mortgage loans originated by its Clients. Individual mortgage loans are
warehoused in the Company’s portfolio only for a short duration, averaging less than 30 days. When instructed by a
Client that a warehoused loan has been sold to an investor, the Company delivers the note to the investor that pays the
Company, which in turn remits the net sales proceeds to the Client.

Agriculture Loans. The Company provides agriculture loans for short-term livestock and crop production,
including rice, cotton, milo and corn, farm equipment financing and agriculture real estate financing. The Company
evaluates agriculture borrowers primarily based on their historical profitability, level of experience in their particular
industry segment, overall financial capacity and the availability of secondary collateral to withstand economic and
natural variations common to the industry. Because agriculture loans present a higher level of risk associated with
events caused by nature, the Company routinely makes on-site visits and inspections in order to identify and monitor
such risks.

56

Consumer Loans. Consumer loans made by the Company include direct “A”-credit automobile loans,
recreational vehicle loans, boat loans, home improvement loans, personal loans (collateralized and uncollateralized)
and deposit account collateralized loans. The terms of these loans typically range from 12 to 180 months and vary
based upon the nature of collateral and size of loan. Generally, consumer loans entail greater risk than do real estate
secured loans, particularly in the case of consumer loans that are unsecured or collateralized by rapidly depreciating
assets such as automobiles. In such cases, any repossessed collateral for a defaulted consumer loan may not provide
an adequate source of repayment for the outstanding loan balance. The remaining deficiency often does not warrant
further substantial collection efforts against the borrower beyond obtaining a deficiency judgment. In addition,
consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to
be adversely affected by job loss, divorce, illness, personal bankruptcy or death. Furthermore, the application of
various federal and state laws may limit the amount which can be recovered on such loans.

Loan Maturities. The contractual maturity ranges of the Company’s loan portfolio, excluding loans held for sale
of $5.7 million and Warehouse Purchase Program loans of $822.2 million, by type of loan and the amount of such
loans with predetermined interest rates and variable rates in each maturity range as of December 31, 2023 are
summarized in the following table. Contractual maturities are based on contractual amounts outstanding and do not
include loan purchase discounts of $27.9 million.

Nonperforming Assets

Nonperforming assets include loans on nonaccrual status, accruing loans 90 days or more past due, repossessed
assets and real estate which has been acquired through foreclosure and is awaiting disposition. Nonperforming assets
do not include PCD loans unless the loan has deteriorated since the acquisition date.

The Company has several procedures in place to assist it in maintaining the overall quality of its loan portfolio.
The Company has established underwriting guidelines to be followed by its officers, and the Company also monitors
its delinquency levels for any negative or adverse trends. Nevertheless, the Company’s loan portfolio could become
subject to increasing pressures from deteriorating borrower credit due to general economic conditions.

As part of the on-going monitoring of the Company’s loan portfolio and the methodology for calculating the
allowance for credit losses on loans, management grades each loan from 1 to 9. For certain loans in risk grades 7 to 9,
a specific reserve may be required when calculating the allowance for credit losses on loans.

The Company generally places a loan on nonaccrual status and ceases accruing interest when the payment of
principal or interest is delinquent for 90 days, or earlier in some cases, unless the loan is in the process of collection
and the underlying collateral fully supports the carrying value of the loan. A loan may be returned to accrual status
when all the principal and interest amounts contractually due are brought current and future principal and interest
amounts contractually due are reasonably assured, which is typically evidenced by a sustained period (at least six
months) of repayment performance by the borrower.

With respect to potential problem loans, an evaluation of borrower overall financial condition is made, together
with an appraisal for loans collateralized by real estate, to determine the need, if any, for possible write-downs or
appropriate additions to the allowance for credit losses on loans.

The following table presents information regarding past due loans and nonperforming assets at the dates

The Company had $72.7 million in nonperforming assets at December 31, 2023 compared with $27.5 million
at December 31, 2022 and $28.1 million at December 31, 2021. The increase in 2023 was primarily due to the Merger.
The nonperforming assets consisted of 292 separate credits or other real estate properties at December 31, 2023,
compared with 170 at December 31, 2022 and 157 at December 31, 2021. The Company had $68.7 million, $19.6
million and $26.3 million in nonaccrual loans at December 31, 2023, 2022 and 2021, respectively.

At December 31, 2023, of the total nonperforming assets, $30.6 million resulted from originated loans, $3.2
million resulted from re-underwritten acquired loans, $8.6 million resulted from Non-PCD loans and $30.3 million
resulted from PCD loans. At December 31, 2022, of the total nonperforming assets, $18.4 million resulted from
originated loans, $2.1 million resulted from re-underwritten acquired loans, $6.8 million resulted from Non-PCD loans

59

and $168 thousand resulted from PCD loans. A PCD loan becomes impaired when there is a deterioration in projected
cash flows after acquisition.

Nonperforming assets were 0.34% and 0.15% of total loans and other real estate at December 31, 2023 and
2022, respectively. The allowance for credit losses on loans as a percentage of total nonperforming loans was 468.9%
at December 31, 2023 and 1102.9% at December 31, 2022.

(1) There was no net charge-off activity on Warehouse Purchase Program loans during the periods presented.

The allowance for credit losses is adjusted through charges to earnings in the form of a provision for credit
losses. Management has established an allowance for credit losses which it believes is adequate as of December 31,
2023 for estimated losses in the Company’s loan portfolio. The amount of the allowance for credit losses on loans is
affected by the following: (1) charge-offs of loans that occur when loans are deemed uncollectible and decrease the
allowance, (2) recoveries on loans previously charged off that increase the allowance, (3) provisions for credit losses
charged to earnings that increase the allowance, and (4) provision releases returned to earnings that decrease the
allowance. Based on an evaluation of the loan portfolio and consideration of the factors listed below, management
presents a quarterly review of the allowance for credit losses to the Bank’s Board of Directors, indicating any change
in the allowance since the last review and any recommendations as to adjustments in the allowance. Although
management believes it uses the best information available to make determinations with respect to the allowance for
credit losses, future adjustments may be necessary if economic conditions or borrower performance differ from the
assumptions used in making the initial determinations.

60

The Company’s allowance for credit losses on loans consists of two components: (1) a specific valuation
allowance based on expected lifetime losses on specifically identified loans and (2) a general valuation allowance
based on historical lifetime loan loss experience, current economic conditions, reasonable and supportable forecasted
economic conditions and other qualitative risk factors both internal and external to the Company.

In setting the specific valuation allowance, the Company follows a loan review program to evaluate the credit
risk in the total loan portfolio and assigns risk grades to each loan. Through this loan review process, the Company
maintains an internal list of impaired loans which, along with the delinquency list of loans, helps management assess
the overall quality of the loan portfolio and the adequacy of the allowance for credit losses. All loans that have been
identified as impaired are reviewed on a quarterly basis in order to determine whether a specific reserve is required.
For certain impaired loans, the Company allocates a specific loan loss reserve primarily based on the value of the
collateral securing the impaired loan. The specific reserves are determined on an individual loan basis. Loans for
which specific reserves are provided are excluded from the general valuation allowance described below.

In connection with this review of the loan portfolio, the Company considers risk elements attributable to

particular loan types or categories in assessing the quality of individual loans. Some of the risk elements include:

•

•

•

•

•

•

•

for 1-4 family residential mortgage loans, borrower’s ability to repay the loan, including a consideration
of the debt to income ratio and employment and income stability, the loan to value ratio, and the age,
condition and marketability of collateral;

for commercial mortgage loans and multifamily residential loans, the debt service coverage ratio (income
from the property in excess of operating expenses compared to loan payment requirements), operating
results of the owner in the case of owner-occupied properties, the loan to value ratio, the age and condition
of the collateral and the volatility of income, property value and future operating results typical of
properties of that type;

for construction, land development and other land loans, the perceived feasibility of the project including
the ability to sell developed lots or improvements constructed for resale or the ability to lease property
constructed for lease, the quality and nature of contracts for presale or prelease, if any, experience and
ability of the developer and loan to value ratio;

for commercial and industrial loans, the operating results of the commercial, industrial or professional
enterprise, the borrower’s business, professional and financial ability and expertise, the specific risks and
volatility of income and operating results typical for businesses in that category and the value, nature and
marketability of collateral;

for the Warehouse Purchase Program, the capitalization and liquidity of the mortgage banking client, the
operating experience, the Client’s satisfactory underwriting of purchased loans and the consistent
timeliness by the Client of loan resale to investors;

for agriculture real estate loans, the experience and financial capability of the borrower, projected debt
service coverage of the operations of the borrower and loan to value ratio; and

for non-real estate agriculture loans, the operating results, experience and financial capability of the
borrower, historical and expected market conditions and the value, nature and marketability of collateral.

In addition, for each category, the Company considers secondary sources of income and the financial strength

and credit history of the borrower and any guarantors.

In determining the amount of the general valuation allowance, management considers factors such as historical
lifetime loan loss experience, concentration risk of specific loan types, the volume, growth and composition of the
Company’s loan portfolio, current economic conditions and reasonable and supportable forecasted economic
conditions that may affect borrower ability to pay and the value of collateral, the evaluation of the Company’s loan
portfolio through its internal loan review process, other qualitative risk factors both internal and external to the
Company and other relevant factors. Historical lifetime loan loss experience is determined by utilizing an open-pool
(“cumulative loss rate”) methodology. Adjustments to the historical lifetime loan loss experience are made for
differences in current loan pool risk characteristics such as portfolio concentrations, delinquency, non-accrual, and
watch list levels, as well as changes in current and forecasted economic conditions such as unemployment rates,

61

property and collateral values, and other indices relating to economic activity. The utilization of reasonable and
supportable forecasts includes an immediate reversion to lifetime historical loss rates. Based on a review of these
factors for each loan type, the Company applies an estimated percentage to the outstanding balance of each loan type,
excluding any loan that has a specific reserve. Allocation of a portion of the allowance to one category of loans does
not preclude its availability to absorb losses in other categories.

A change in the allowance for credit losses can be attributable to several factors, most notably (1) specific
reserves identified for impaired loans, (2) historical lifetime credit loss information, (3) changes in current and
forecasted environmental factors and (4) growth in the balance of loans.

Changes in the Company’s asset quality are reflected in the allowance in several ways. Specific reserves that
are calculated on a loan-by-loan basis and the qualitative assessment of all other loans reflect current changes in the
credit quality of the loan portfolio. Historical lifetime credit losses, on the other hand, are based on an open-pool
(“cumulative loss rate”) methodology, which is then applied to estimate lifetime credit losses in the loan portfolio. A
deterioration in the credit quality of the loan portfolio in the current period would increase the historical lifetime loss
rate to be applied in future periods, just as an improvement in credit quality would decrease the historical lifetime loss
rate.

The allowance for credit losses is further determined by the size of the loan portfolio subject to the allowance
methodology and environmental factors that include Company-specific risk indicators and general economic
conditions, both of which are constantly changing. The Company evaluates the economic and portfolio-specific factors
on a quarterly basis to determine a qualitative component of the general valuation allowance. The factors include
current economic metrics, reasonable and supportable forecasted economic metrics, business conditions, delinquency
trends, credit concentrations, nature and volume of the portfolio and other adjustments for items not covered by
specific reserves and historical lifetime loss experience. Management’s assessment of qualitative factors is a
statistically based approach to determine the loss rate adjustment associated with such factors. Based on the
Company’s actual historical lifetime loan loss experience relative to economic and loan portfolio-specific factors at
the time the losses occurred, management is able to identify the expected level of lifetime losses as of the date of
measurement. The correlation of historical loss experience with current and forecasted economic conditions provides
an estimate of lifetime losses that has not been previously factored into the general valuation allowance by the
determination of specific reserves and lifetime historical losses. Additionally, the Company considers qualitative
factors not easily quantified and the possibility of model imprecision.

Utilizing the aggregation of specific reserves, historical

loss experience and a qualitative component,

management is able to determine the valuation allowance to reflect the full lifetime loss.

The Company accounts for its acquisitions using the acquisition method of accounting. Accordingly, the assets,
including loans, and liabilities of the acquired entity were recorded at their fair values at the acquisition date. These
fair value estimates associated with acquired loans, and based on a discounted cash flow model, include estimates
related to market interest rates and undiscounted projections of future cash flows that incorporate expectations of
prepayments and the amount and timing of principal, interest and other cash flows, as well as any shortfalls thereof.

Non-PCD loans that were not deemed impaired subsequent to the acquisition date are considered non-impaired
and are evaluated as part of the general valuation allowance. Non-PCD loans that have deteriorated to an impaired
status subsequent to acquisition are evaluated for a specific reserve on a quarterly basis which, when identified, is
added to the allowance for credit losses. The Company reviews impaired Non-PCD loans on a loan-by-loan basis and
determines the specific reserve based on the difference between the recorded investment in the loan and one of three
factors: expected future cash flows, observable market price or fair value of the collateral. Because essentially all of
the Company’s impaired Non-PCD loans have been collateral-dependent, the amount of the specific reserve
historically has been determined by comparing the fair value of the collateral securing the Non-PCD loan with the
recorded investment in such loan. In the future, the Company will continue to analyze impaired Non-PCD loans on a
loan-by-loan basis and may use an alternative measurement method to determine the specific reserve, as appropriate
and in accordance with applicable accounting standards.

62

PCD loans are monitored individually or on a pooled basis quarterly to assess for changes in expected cash
flows subsequent to acquisition. If a deterioration in cash flows is identified, an increase to the PCD reserves for that
individual loan or pool of loans is made. PCD loans were recorded at their acquisition date fair values, which were
based on expected cash flows and considers estimates of expected future credit losses. The Company’s estimates of
loan fair values at the acquisition date may be adjusted for a period of up to one year as the Company continues to
evaluate its estimate of expected future cash flows at the acquisition date. If the Company determines that losses arose
after the acquisition date, the additional losses will be reflected as a provision for credit losses. See “Critical
Accounting Estimates” above for more information.

As described in the section captioned “Critical Accounting Estimates” above, the Company’s determination of
the allowance for credit losses involves a high degree of judgment and complexity. The Company’s analysis of
qualitative, or environmental, factors on pools of loans with common risk characteristics, in combination with the
quantitative historical lifetime loss information and specific reserves, provides the Company with an estimate of
lifetime losses. The allowance must reflect changes in the balance of loans subject to the allowance methodology, as
well as the estimated lifetime losses associated with those loans.

The following table shows the allocation of the allowance for credit losses among various categories of loans
and certain other information as of the dates indicated. The allocation is made for analytical purposes and is not
necessarily indicative of the categories in which future losses may occur. The total allowance is available to absorb
losses from any loan category.

At December 31, 2023, the allowance for credit losses on loans totaled $332.4 million or 1.57% of total loans,
including acquired loans with discounts, an increase of $50.8 million or 18.0% compared to the allowance for credit
losses on loans totaling $281.6 million or 1.49% of total loans, including acquired loans with discounts, for December
31, 2022, primarily due to the Merger. Net charge-offs were $38.0 million for the year ended December 31, 2023. Net
charge-offs for the year ended December 31, 2023 included $16.6 million related to resolved PCD loans and
$15.0 million related to one commercial real estate loan acquired in a previous merger. The PCD loans had reserves
of $16.3 million assigned as of the acquisition date. Additionally, reserves on PCD loans increased by $76.8 million
due to the Merger and $23.5 million of reserves on resolved PCD loans was released to the general reserve.

At December 31, 2022, the allowance for credit losses on loans totaled $281.6 million or 1.49% of total loans,
including acquired loans with discounts, a decrease of $4.8 million or 1.7% compared to the allowance for credit
losses on loans totaling $286.4 million or 1.54% of total loans, including acquired loans with discounts, for December
31, 2021. Net charge-offs were $4.8 million for the year ended December 31, 2022. Net charge-offs for the year ended
December 31, 2022 did not include any PCD loans and $8.2 million of specific reserves on resolved PCD loans was
released to the general reserve during the period. PPP loans totaling $6.2 million as of December 31, 2022, are fully
guaranteed by the SBA and do not carry an allowance.

At December 31, 2023, $222.4 million of the allowance for credit losses on loans was attributable to originated
loans compared with $209.5 million of the allowance at December 31, 2022, an increase of $12.9 million or 6.2%. At
December 31, 2023, $30.0 million of the allowance for credit losses on loans was attributable to re-underwritten
acquired loans compared with $37.6 million of the allowance at December 31, 2022, a decrease of $7.7 million or
20.4%. At December 31, 2023, $22.3 million of the allowance for credit losses on loans was attributable to Non-PCD
loans compared with $17.4 million of the allowance at December 31, 2022, an increase of $4.9 million or 28.4%. At
December 31, 2023, $57.7 million of the allowance for credit losses on loans attributable to PCD loans compared with
$17.1 million of the allowance at December 31, 2022, an increase of $40.6 million.

At December 31, 2023, the Company had $27.9 million of total outstanding accretable discounts on Non-PCD
and PCD loans. At December 31, 2022, the Company had $5.6 million of total outstanding accretable discounts on
Non-PCD and PCD loans.

The Company believes that the allowance for credit losses on loans at December 31, 2023 is adequate to absorb
expected lifetime losses that may be realized from the loan portfolio as of such date. Nevertheless, the Company could
sustain losses in future periods that could be substantial in relation to the size of the allowance at December 31, 2023.

Allowance for Credit Losses on Off-Balance Sheet Credit Exposures

The allowance for credit losses on off-balance sheet credit exposures estimates expected credit losses over the
contractual period in which there is exposure to credit risk via a contractual obligation to extend credit, except when
an obligation is unconditionally cancelable by the Company. The allowance is adjusted by provisions for credit losses
charged to earnings that increase the allowance, or by provision releases returned to earnings that decrease the
allowance. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected
credit losses on the commitments expected to fund. The estimate of commitments expected to fund is affected by
historical analysis of utilization rates. The expected credit loss rates applied to the commitments expected to fund are
affected by the general valuation allowance utilized for outstanding balances with the same underlying assumptions
and drivers. As of December 31, 2023 and 2022, the Company had $36.5 million and $29.9 million, respectively, in
allowance for credit losses on off-balance sheet credit exposures, with the increase due to the Merger. The allowance
for credit losses on off-balance sheet credit exposures is a separate line item on the Company’s consolidated balance
sheet.

The following table represents a rollforward of the allowance for credit losses on off-balance sheet credit

exposures for the periods shown.

Securities

The Company uses its securities portfolio to manage interest rate risk and as a source of income and liquidity
for cash requirements. At December 31, 2023, the carrying amount of investment securities totaled $12.80 billion, a
decrease of $1.67 billion or 11.6% compared with $14.48 billion at December 31, 2022. At December 31, 2023,
securities represented 33.2% of total assets compared with 38.4% of total assets at December 31, 2022.

At the date of purchase, the Company is required to classify debt and equity securities into one of three
categories: held to maturity, trading or available for sale. At each reporting date, the appropriateness of the
classification is reassessed. Investments in debt securities are classified as held to maturity and measured at amortized
cost in the financial statements only if management has the positive intent and ability to hold those securities to
maturity. Securities that are bought and held principally for the purpose of selling them in the near term are classified
as trading and measured at fair value in the financial statements with unrealized gains and losses included in earnings.
Investments not classified as either held to maturity or trading are classified as available for sale and measured at fair
value in the financial statements with unrealized gains and losses reported, net of tax, in a separate component of
shareholders’ equity until realized.

The investment securities portfolio is measured for expected credit losses by segregating the portfolio into two
general classifications and applying the appropriate expected credit losses methodology. Investment securities
classified as available for sale or held to maturity are evaluated for expected credit losses under FASB ASC 326,
“Financial Instruments – Credit Losses.”

Available for sale securities. For available for sale securities in an unrealized loss position, the amount of the
expected credit losses recognized in earnings depends on whether an entity intends to sell the security or more likely
than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit
loss. If an entity intends to sell or more likely than not will be required to sell the security before recovery of its
amortized cost basis less any current-period credit loss, the expected credit losses will be recognized in earnings equal
to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If an
entity does not intend to sell the security and it is not more likely than not that the entity will be required to sell the
security before recovery of its amortized cost basis less any current-period loss, the expected credit losses will be
separated into the amount representing the credit-related portion of the impairment loss (“credit loss”) and the
noncredit portion of the impairment loss (“noncredit portion”). The amount of the total expected credit losses related
to the credit loss is determined based on the difference between the present value of cash flows expected to be collected
and the amortized cost basis, and such difference is recognized in earnings. The amount of the total expected credit
losses related to the noncredit portion is recognized in other comprehensive income, net of applicable taxes. The
previous amortized cost basis less the expected credit losses recognized in earnings will become the new amortized
cost basis of the investment.

As of December 31, 2023, management does not have the intent to sell any of the securities classified as
available for sale before a recovery of cost. In addition, management believes it is more likely than not that the
Company will not be required to sell any of its investment securities before a recovery of cost. The unrealized losses
are largely due to changes in market interest rates and spread relationships since the time the underlying securities
were purchased. The fair value is expected to recover as the securities approach their maturity date or repricing date
or if market yields for such investments decline. Management does not believe any of the securities are impaired due
to reasons of credit quality. Accordingly, as of December 31, 2023, management believes that there is no potential for
credit losses on available for sale securities.

68

Held to maturity securities. The Company’s held to maturity investments include mortgage-related bonds
issued by either the Government National Mortgage Corporation (“Ginnie Mae”), Federal National Mortgage
Association (“Fannie Mae”) or Federal Home Loan Mortgage Corporation (“Freddie Mac”). Ginnie Mae issued
securities are explicitly guaranteed by the U.S. government, while Fannie Mae and Freddie Mac issued securities are
fully guaranteed by those respective United States government-sponsored agencies, and conditionally guaranteed by
the full faith and credit of the United States. The Company’s held to maturity securities also include taxable and tax-
exempt municipal securities issued primarily by school districts, utility districts and municipalities located in Texas.
The Company’s investment in municipal securities is exposed to credit risk. The securities are highly rated by major
rating agencies and regularly reviewed by management. A significant portion are guaranteed or insured by either the
Texas Permanent School Fund, Assured Guaranty or Build America Mutual. As of December 31, 2023, the Company’s
municipal securities represent 0.9% of the securities portfolio. Management has the ability and intent to hold the
securities classified as held to maturity until they mature, at which time the Company will receive full value for the
securities. Accordingly, as of December 31, 2023, management believes that there is no potential for material credit
losses on held to maturity securities.

The following table summarizes the contractual maturity of securities and their weighted average yields as of
December 31, 2023. The contractual maturity of a mortgage-backed security is the date at which the last underlying
mortgage matures. The weighted average life of the Company’s securities portfolio is 4.95 years, with a modified
duration of 4.07 at December 31, 2023. Available for sale securities are shown at fair value and held to maturity
securities are shown at amortized cost. For purposes of the table below, tax-exempt states and political subdivisions
are calculated on a tax equivalent basis.

The contractual maturity of mortgage-backed securities and collateralized mortgage obligations is not a reliable
indicator of their expected life because borrowers have the right to prepay their obligations at any time with or without
call or prepayment penalties. Mortgage-backed securities monthly pay downs cause the average lives of the securities
to be much different than their stated lives. During a period of increasing interest rates, fixed rate mortgage-backed
securities do not tend to experience heavy prepayments of principal, and consequently, the average life of this security
will be lengthened. If interest rates begin to fall, prepayments may increase, thereby shortening the estimated life of
this security.

At December 31, 2023 and 2022, the Company did not own securities of any one issuer (other than the U.S.
government and its agencies) for which aggregate adjusted cost exceeded 10% of the consolidated shareholders’ equity
at such respective dates.

The average tax equivalent yield of the securities portfolio was 2.07% as of December 31, 2023 compared with
2.02% and 1.74% as of December 31, 2022 and 2021, respectively. This increase was primarily due to the investment
in higher-yielding securities. The average tax equivalent yield on the securities portfolio is based upon expected
prepayment speeds, other industry standard projections and on a 21% tax rate in 2023, 2022 and 2021.

69

The average yield excluding the tax equivalent adjustment was 2.06% for the year ended December 31, 2023
compared with 1.78% for the year ended December 31, 2022 and 1.55% for the year ended December 31, 2021. The
overall change in the average securities portfolio over the comparable periods was primarily funded by average deposit
growth and other borrowings.

Mortgage-backed securities are securities that have been developed by pooling a number of real estate
mortgages and which are principally issued by federal agencies such as Ginnie Mae, Fannie Mae and Freddie Mac.
These securities are deemed to have high credit ratings, and minimum regular monthly cash flows of principal and
interest are guaranteed by the issuing agencies.

Unlike U.S. Treasury and U.S. government agency securities, which have a lump sum payment at maturity,
mortgage-backed securities provide cash flows from regular principal and interest payments and principal
prepayments throughout the lives of the securities. Premiums and discounts on mortgage-backed securities are
amortized over the expected life of the security and may be impacted by prepayments. As such, mortgage-backed
securities which are purchased at a premium will generally suffer decreasing net yields as interest rates drop because
homeowners tend to refinance their mortgages resulting in prepayments and an acceleration of premium amortization.
Securities purchased at a discount will obtain higher net yields in a decreasing interest rate environment as
prepayments result in an acceleration of discount accretion. At December 31, 2023, 81.6% of the mortgage-backed
securities held by the Company had contractual final maturities of more than ten years with a weighted average life
of 5.54 years.

Collateralized mortgage obligations (“CMOs”) are bonds that are backed by pools of mortgages. The pools can
be Ginnie Mae, Fannie Mae or Freddie Mac pools or they can be private-label pools. CMOs are designed so that the
mortgage collateral will generate a cash flow sufficient to provide for the timely repayment of the bonds. So long as
the collateral cash flow is adequate to meet scheduled bond payments, the mortgage collateral pool can be structured
to accommodate various desired bond repayment schedules. This is accomplished by dividing the bonds into classes
to which payments on the underlying mortgage pools are allocated in different order. The bond’s cash flow, for
example, can be dedicated to one class of bondholders at a time, thereby increasing call protection to bondholders. In
private-label CMOs, losses on underlying mortgages are directed to the most junior of all classes and then to the
classes above in order of increasing seniority, which means that the senior classes have enough credit protection to be
given the highest credit rating by the rating agencies.

Deposits

The Company’s lending and investing activities are primarily funded by deposits. The Company offers a variety
of deposit accounts having a wide range of interest rates and terms including demand, savings, money market and
time accounts. The Company relies primarily on competitive pricing policies and customer service to attract and retain
these deposits.

Total deposits at December 31, 2023 were $27.18 billion, a decrease of $1.35 billion or 4.7% compared with
$28.53 billion at December 31, 2022, primarily due to a decrease in business deposits and public fund deposits,
partially offset by an increase in Merger acquired deposits. Total deposits at December 31, 2022 were $28.53 billion,
a decrease of $2.24 billion or 7.3% compared with $30.77 billion at December 31, 2021, primarily due to a decrease
in public fund deposits. Noninterest-bearing deposits at December 31, 2023 were $9.78 billion compared with $10.92
billion at December 31, 2022, a decrease of $1.14 billion or 10.4%. Noninterest-bearing deposits at December 31,
2022 were $10.92 billion compared with $10.75 billion at December 31, 2021, an increase of $165.4 million or 1.5%.
Interest-bearing deposits at December 31, 2023 were $17.40 billion, a decrease of $214.8 million or 1.2% compared
with $17.62 billion at December 31, 2022. Interest-bearing deposits at December 31, 2022 were $17.62 billion, a
decrease of $2.4 billion or 12.0% compared with $20.02 billion at December 31, 2021.

Bank Term Funding Program—During the second quarter of 2023, the Bank began participating in the Federal
Reserve Board’s BTFP. Under the BTFP program, eligible depository institutions can obtain loans of up to one year
in length by pledging U.S. Treasuries, agency debt and mortgage-backed securities, and other qualifying assets as
collateral. These assets are valued at par. Eligible depository institutions can request advances under the BTFP until
at least March 11, 2024. At December 31, 2023, the Bank had secured borrowing capacity of $4.40 billion
collateralized by the par value of pledged securities totaling $4.40 billion. At December 31, 2023, the balance
outstanding was $3.73 billion consisting of a one term advance maturing in December 2024 with a weighted average
interest rate of 4.83%.

FHLB advances and long-term notes payable—The Company has an available line of credit with the FHLB of
Dallas, which allows the Company to borrow on a collateralized basis. The Company’s FHLB advances are typically
considered short-term borrowings and are used to manage liquidity as needed. Maturing advances are replaced by
drawing on available cash, making additional borrowings or through increased customer deposits. At December 31,
2023, the Company had total borrowing capacity of $10.85 billion under this line. At December 31, 2023, the
Company had no FHLB advances or long-term notes payable balance outstanding.

Securities sold under repurchase agreements with Company customers—At December 31, 2023, the Company
had $309.3 million in securities sold under repurchase agreements compared with $428.1 million at December 31,
2022, a decrease of $118.9 million or 27.8%, with weighted average interest rates paid of 2.42% and 0.58% for the
years ended December 31, 2023 and 2022, respectively. Repurchase agreements are generally settled on the following
business day; however, approximately $3.0 million of repurchase agreements outstanding at December 31, 2023 have
maturity dates ranging from 12 to 24 months. All securities sold under repurchase agreements are collateralized by
certain pledged securities.

Subordinated debentures—On May 1, 2023, in connection with the acquisition of First Bancshares, the
Company assumed the obligation related to $3.1 million of Floating Rate Junior Subordinated Deferrable Interest
Debentures and trust preferred securities (the "Subordinated Debentures"), which the Company redeemed on
September 18, 2023. Accordingly, as of December 31, 2023, the Company had no Subordinated Debentures
outstanding.

Interest Rate Sensitivity and Market Risk

The Company’s asset liability and funds management policy provides management with the guidelines for
effective funds management, and the Company has established a measurement system for monitoring its net interest
rate sensitivity position. The Company manages its sensitivity position within established guidelines.

As a financial institution, the Company’s primary component of market risk is interest rate volatility.
Fluctuations in interest rates ultimately will impact both (1) the level of income and expense recorded on most of the
Company’s assets and liabilities and (2) the market value of all interest-earning assets and interest-bearing liabilities,
other than those which have a short term to maturity. Interest rate risk is the potential of economic losses due to future
interest rate changes. These economic losses can be reflected as a loss of future net interest income, a loss of current
fair market values, or both. The objective is to measure the effect on net interest income and to adjust the balance
sheet to minimize the inherent risk while maximizing income.

The Company primarily manages its exposure to interest rates by structuring its balance sheet in the ordinary
course of business. The Company does not employ material amounts of instruments such as leveraged derivatives,
interest rate swaps, financial options, financial future contracts or forward delivery contracts for the purpose of
reducing interest rate risk. Based upon the nature of the Company’s operations, with the exception of how commodity
prices may impact the Company’s borrowers’ ability to repay loans, the Company is not subject to foreign exchange
or commodity price risk. The Company is not involved in trading assets for its own account.

The Company’s exposure to interest rate risk is managed by the Asset Liability Committee (“ALCO”), which
consists of senior officers of the Company, in accordance with policies approved by the Company’s Board of
Directors. The ALCO formulates strategies based on appropriate levels of interest rate risk. In determining the
appropriate level of interest rate risk, the ALCO considers the impact on earnings and capital of the current outlook
on interest rates, potential changes in interest rates, regional economies, liquidity, business strategies and other factors.

72

The ALCO meets regularly to review, among other things, the sensitivity of assets and liabilities to interest rate
changes, the book and market values of assets and liabilities, unrealized gains and losses, purchase and sale activities,
commitments to originate loans and the maturities of investments and borrowings. Additionally, the ALCO reviews
liquidity, cash flow flexibility, maturities of deposits and consumer and commercial deposit activity. Management
uses two methodologies to manage interest rate risk: (1) an analysis of relationships between interest-earning assets
and interest-bearing liabilities; and (2) an interest rate shock simulation model. The Company has traditionally
managed its business to minimize its overall exposure to changes in interest rates.

The Company primarily uses an interest rate risk simulation model to evaluate the interest rate sensitivity of
net interest income and the balance sheet. Contractual maturities and repricing opportunities of loans are incorporated
in the model as are prepayment assumptions, maturity data and call options within the investment portfolio.
Assumptions based on past experience are incorporated into the model for nonmaturity deposit accounts. Interest rate
shocks are applied to a static balance sheet to estimate the potential impact on net interest income and the aggregated
market value of the balance sheet. As of December 31, 2023, these interest rate shocks consisted of instantaneous and
parallel shifts in the yield curve moving from – 400 basis points to + 400 basis points, in 100 basis-point increments.
The forecasted net interest income assuming no change in interest rates is compared to the forecasted net interest
income in the shocks to measure the sensitivity of the Company’s earnings to changes in interest rates. Other
simulations are run on a regular basis that include the gradual and rapid ramping of interest rates, yield curve twists
and changes in the balance sheet composition.

The following table summarizes the simulated change in net interest income at the 12-month horizon,

considering the balance sheet composition as of December 31, 2023 and 2022:

Percent Change in Net Interest Income

Change in Interest Rates (Basis Points)
+200
+100
Base
-100
-200

December 31, 2023
(5.5)%
(2.4)%
0.0%
3.1%
3.2%

December 31, 2022
2.0%
1.2%
0.0%
(3.4)%
(7.65)%

The Company continues to manage its asset sensitivity within the scope of its risk tolerances and changing
market conditions. At December 31, 2023, a projected 200 basis point increase in rates resulted in a projected decrease
in net interest income of 5.5% compared with a projected 2.0% increase in net interest income at December 31, 2022.
These projections can be impacted by a variety of factors, including changes in interest rates, changes in model
assumptions and shifts in the Company’s balance sheet composition. During 2023, the Company increased its volume
of borrowings to fund loan growth and deposit outflows. The growth in fixed rate residential mortgage loans along
with the higher borrowing balances were the primary factors causing the Company’s liability sensitive position at
December 31, 2023.

The results are significantly influenced by the behavior of demand, money market and savings deposits and the
overall balance sheet composition during such rate fluctuations. The Company has found that, historically, interest
rates on these deposits change more slowly than changes in the discount and federal funds rates. This assumption is
incorporated into the simulation model and is generally not fully reflected in a gap analysis. The assumptions
incorporated into the model are inherently uncertain and, as a result, the model cannot precisely measure future net
interest income or precisely predict the impact of fluctuations in market interest rates on net interest income. Actual
results will differ from the model’s simulated results due to timing, magnitude and frequency of interest rate changes
as well as changes in market conditions and the application and timing of various management strategies.

LIBOR Transition

On September 30, 2021, the Company began transitioning away from London Inter-Bank Offered Rate
(“LIBOR”) to the Secured Overnight Financing Rate (“SOFR”) or other alternative variable rate indexes for its
interest-rate swaps and loans historically using LIBOR as an index. As of December 31, 2023, the Company's interest
rate swaps and loan portfolio used SOFR as the index rate. As of December 31, 2022, LIBOR was used as an index

73

rate for approximately 88.2% of the Company’s interest-rate swaps and approximately 1.5% of the Company’s loan
portfolio.

Liquidity

Liquidity involves the Company’s ability to raise funds to support asset growth and acquisitions or reduce assets
to meet deposit withdrawals and other payment obligations, to maintain reserve requirements and otherwise to operate
the Company on an ongoing basis and manage unexpected events. During 2023 and 2022, the Company’s liquidity
needs were primarily met by core deposits, security and loan maturities and amortizing investment and loan portfolios.
During 2023, the Company also utilized advances from the FHLB of Dallas and Federal Reserve Board’s BTFP.
Although access to purchased funds from correspondent banks may be available and has been utilized on occasion to
take advantage of investment opportunities, the Company does not generally rely on this external funding source.

The following table illustrates, during the years presented, the mix of the Company’s funding sources and the
average assets in which those funds are invested as a percentage of the Company’s average total assets for the periods
indicated. Average assets totaled $38.97 billion for 2023 compared with $37.72 billion for 2022.

The Company’s largest source of funds is deposits, and the Company’s principal uses of funds are loans and
securities. The Company does not expect a change in the source or use of its funds in the foreseeable future. The
Company’s average deposits decreased 8.6% for the year ended December 31, 2023 compared with the year ended
December 31, 2022. The Company’s average loans increased 13.0% for the year ended December 31, 2023 compared
with the year ended December 31, 2022. The Company predominantly invests excess deposits in government-backed
securities until the funds are needed to fund loan growth. The Company’s securities portfolio has a weighted average
life of 4.95 years and a modified duration of 4.07 at December 31, 2023.

As of December 31, 2023, the Company had outstanding $4.60 billion in commitments to extend credit, $79.8
million in commitments associated with outstanding standby letters of credit and $1.12 billion in commitments
associated with unused capacity on Warehouse Purchase Program loans. Since commitments associated with letters
of credit and commitments to extend credit may expire unused, the total outstanding may not necessarily reflect the
actual future cash funding requirements.

As of December 31, 2023, the Company had no exposure to future cash requirements associated with known

uncertainties or capital expenditures of a material nature.

74

As of December 31, 2023, the Company had cash and cash equivalents of $458.4 million compared with $424.1
million at December 31, 2022, an increase of $34.3 million or 8.1%. The increase was primarily due to net proceeds
from short-term borrowings of $1.67 billion, net proceeds from maturities and principal paydowns of investment
securities of $1.88 billion and net cash provided by operating activities of $646.4 million, partially offset by a decrease
in deposits of $2.93 billion, a net increase in loans of $759.0 million, payment of cash dividends of $205.7 million,
repurchase of common stock of $72.2 million, a decrease in securities sold under repurchase agreements of $168.7
million and net cash used in the purchase of First Bancshares of $24.4 million.

Share Repurchases

On January 16, 2024, the Company announced a stock repurchase program under which the Company could
repurchase up to 5%, or approximately 4.7 million shares, of its outstanding common stock over a one-year period
expiring on January 16, 2025, at the discretion of management. Under the stock repurchase program, the Company
may repurchase shares from time to time at prevailing market prices, through open-market purchases or privately
negotiated transactions, depending upon market conditions. Repurchases under this program may also be made in
transactions outside the safe harbor during a pending merger, acquisition or similar transaction. The timing and actual
number of shares repurchased will depend on a variety of factors including price, corporate and regulatory
Shares of stock
requirements, market conditions, and other corporate liquidity requirements and priorities.
repurchased are held as authorized but unissued shares. The Company is not obligated to purchase any particular
number of shares, and the Company may suspend, modify or terminate the program at any time and for any reason
without prior notice.

On January 17, 2023, the Company announced a stock repurchase program under which the Company could
repurchase up to 5%, or approximately 4.6 million shares, of its outstanding common stock over a one-year period
expiring on January 17, 2024, at the discretion of management. The Company repurchased approximately 1.21 million
shares of its common stock at an average weighted price of $59.88 per share during the year ended December 31,
2023.

On January 18, 2022, the Company announced a stock repurchase program under which the Company could
repurchase up to 5%, or approximately 4.6 million shares, of its outstanding common stock over a one-year period
expiring on January 18, 2023, at the discretion of management. The Company repurchased 981,884 shares of its
common stock at an average weighted price of $66.90 per share during the year ended December 31, 2022.

Contractual Obligations

The Company’s contractual obligations and other commitments to make future payments (other than deposit

obligations and securities sold under repurchase agreements) as of December 31, 2023 are summarized below.

Borrowings

The Company’s future cash payments associated with the Federal Reserve Board’s BTFP as of December 31,
2023 are summarized below. The future interest payments were calculated using the current rate in effect at December
31, 2023. Payments under the BTFP include interest of $173.9 million that will be due over the future periods. These
payments do not include prepayment options that may be available to the Company.

Off-Balance Sheet Items

In the normal course of business, the Company enters into various transactions that, in accordance with GAAP,
are not included in its consolidated balance sheets. The Company enters into these transactions to meet the financing
needs of its customers. These transactions include commitments to extend credit and standby letters of credit, which
involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the
consolidated balance sheets.

The Company’s commitments associated with outstanding standby letters of credit, unused capacity on
Warehouse Purchase Program loans and commitments to extend credit expiring by period as of December 31, 2023
are summarized below. Since commitments associated with letters of credit, unused capacity of Warehouse Purchase
Program loans and commitments to extend credit may expire unused, the amounts shown may not necessarily reflect
the actual future cash funding requirements.

Standby Letters of Credit. Standby letters of credit are written conditional commitments issued by the Company
to guarantee the payment by or performance of a customer to a third party. If the customer does not perform in
accordance with the terms of the agreement with the third party, the Company would be required to fund the
commitment. The maximum potential amount of future payments the Company could be required to make is
represented by the contractual amount of the commitment. If the commitment is funded, the Company would be
entitled to seek recovery from the customer. The Company’s policies generally require that standby letter of credit
arrangements contain security and debt covenants similar to those contained in loan agreements.

Unused Capacity on Warehouse Purchase Program Loans. For Warehouse Purchase Program loans, the
Company has established a maximum purchase facility amount, but reserves the right, at any time, to refuse to buy
any mortgage loans offered for sale by its mortgage originator clients for any reason.

Commitments to Extend Credit. The Company enters into contractual commitments to extend credit, normally
with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of the
Company’s commitments to extend credit are contingent upon customers maintaining specific credit standards at the
time of loan funding. The Company minimizes its exposure to loss under these commitments by subjecting them to
credit approval and monitoring procedures. Management assesses the credit risk associated with certain commitments
to extend credit in determining the level of the allowance for credit losses.

Allowance for Credit Losses on Off-balance Sheet Credit Exposures. The Company records an allowance for
credit losses on off-balance sheet credit exposure that is adjusted through a charge to provision for credit losses on the
Company’s consolidated statement of income. At December 31, 2023 and 2022, this allowance, reported as a separate
line item on the Company’s consolidated balance sheet, totaled $36.5 million and $29.9 million, respectively. The
increase in the allowance was due to the Merger.

Leases

The Company’s leases relate primarily to operating leases for office space and banking centers. The Company
determines if an arrangement is a lease or contains a lease at inception. The Company’s leases have remaining lease
terms of 1 to 15 years, which may include the option to extend the lease when it is reasonably certain for the Company
to exercise that option. Operating lease right-of-use (“ROU”) assets and liabilities are recognized at
the
commencement date based on the present value of lease payments over the lease term. The Company uses its

76

incremental collateralized borrowing rate to determine the present value of lease payments. Short-term leases and
leases with variable lease costs are immaterial and the Company has one sublease arrangement. Sublease income for
the years ended December 31, 2023, 2022 and 2021 was $3.1 million, $3.2 million and $3.1 million, respectively. As
of December 31, 2023, operating lease ROU assets and lease liabilities were approximately $36.8 million. ROU assets
and lease liabilities were classified as other assets and other liabilities, respectively.

As of December 31, 2023, the weighted average remaining lease terms of the Company’s operating leases were
5.1 years. The weighted average discount rate used to determine the lease liabilities as of December 31, 2023 for the
Company’s operating leases was 2.7%. Cash paid for the Company’s operating leases for the years ended December
31, 2023, 2022 and 2021 was $12.0 million, $10.9 million and $12.2 million, respectively. During the year ended
December 31, 2023, the Company obtained $3.6 million in ROU assets in exchange for lease liabilities for eight
operating leases, four of which, reflecting $2.7 million in ROU assets, were related to the Merger.

The Company’s future undiscounted cash payments associated with its operating leases as of December 31,

2023 are summarized below (dollars in thousands).

It is expected that in the normal course of business, expiring leases will be renewed or replaced by leases on

other property or equipment.

Rent expense under all operating lease obligations aggregated approximately $12.1 million, $10.9 million, and

$11.6 million for the years ended December 31, 2023, 2022 and 2021, respectively.

Capital Resources

Capital management consists of providing equity to support the Company’s current and future operations. The
Company is subject to capital adequacy requirements imposed by the Federal Reserve Board, and the Bank is subject
to capital adequacy requirements imposed by the FDIC. Both the Federal Reserve Board and the FDIC have adopted
risk-based capital requirements for assessing bank holding company and bank capital adequacy. These standards
define capital and establish minimum capital requirements in relation to assets and off-balance sheet exposure,
adjusted for credit risk.

In July 2013, the Federal Reserve Board and the FDIC published the Basel III Capital Rules establishing a new
comprehensive capital framework for U.S. banking organizations. The Basel III Capital Rules, among other things,
(1) introduced a new capital measure called “Common Equity Tier 1” (“CET1”), (2) specified that Tier 1 capital
consists of CET1 and “Additional Tier 1 capital” instruments meeting specified requirements, (3) defined CET1
narrowly by requiring that most deductions/ adjustments to regulatory capital measures be made to CET1 and not to
the other components of capital and (4) expanded the scope of the deductions/ adjustments as compared to existing
regulations.

Since being fully phased in on January 1, 2019, the Basel III Capital Rules require the Company to maintain a
capital conservation buffer, composed entirely of CET1, of 2.5%, effectively resulting in minimum ratios of (1) CET1
to risk-weighted assets of 7.0%, (2) Tier 1 capital to risk-weighted assets of 8.5%, (3) total capital (that is, Tier 1 plus
Tier 2) to risk-weighted assets of 10.5% and (4) Tier 1 capital to average quarterly assets as reported on consolidated
financial statements ( known as the “leverage ratio”) of 4.0%. The Bank is subject to capital adequacy guidelines of
the FDIC that are substantially similar to the Federal Reserve Board’s guidelines. Also pursuant to FDICIA, the FDIC
has promulgated regulations setting the levels at which an insured institution such as the Bank would be considered
“well-capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized” and “critically

77

undercapitalized.” Under the FDIC’s regulations, the Bank is classified “well-capitalized” for purposes of prompt
corrective action.

Banking institutions that fail to meet the effective minimum ratios will be subject to constraints on capital
distributions, including dividends and share repurchases, and certain discretionary executive compensation. The
severity of the constraints depends on the amount of the shortfall and the institution’s “eligible retained income” (that
is, four-quarter trailing net income, net of distributions and tax effects not reflected in net income).

In response to the COVID-19 pandemic, in March 2020 the joint federal bank regulatory agencies issued an
interim final rule that allowed banking organizations that implemented CECL in 2020 to mitigate the effects of the
CECL accounting standard in their regulatory capital for two years. This two-year delay is in addition to the three-
year transition period that the agencies had already made available. The Company adopted the option provided by the
interim final rule, which delayed the effects of CECL on its regulatory capital through 2021, after which the effects
will be phased in over a three-year period from January 1, 2022 through December 31, 2024. Under the interim final
rule, the amount of adjustments to regulatory capital deferred until the phase-in period include both the initial impact
of the Company’s adoption of CECL on January 1, 2020 and 25% of subsequent changes in the Company’s allowance
for credit losses during each quarter of the two-year period ending December 31, 2021. The cumulative amount of the
transition adjustments is being phased in over the three-year transition period that began on January 1, 2022, with 75%
recognized in 2022, 50% recognized in 2023, and 25% recognized in 2024.

As of December 31, 2023, the Company’s ratio of CET1 to risk-weighted assets was 15.54%, Tier 1 capital to
risk-weighted assets was 15.54%, total capital to risk-weighted assets was 16.56% and Tier 1 capital to average
quarterly assets was 10.39%.

It is important to note that Warehouse Purchase Program loan volumes can increase significantly on the last day
of the month, potentially leading to a significant difference between the ending and average balance of Warehouse
Purchase Program loans for a given period. At December 31, 2023, Warehouse Purchase Program loans totaled $822.2
million, compared to an average balance of $815.9 million. Because the capital ratios above are calculated using
ending risk-weighted assets and Warehouse Purchase Program loans are risk-weighted at 100%, the end-of-period
increase in these balances can significantly impact the Company’s reported capital ratios.

Total shareholders’ equity increased to $7.08 billion at December 31, 2023, compared with $6.70 billion at
December 31, 2022, an increase of $380.0 million or 5.7%. The increase was primarily the result of the common stock
issuance in connection with the Merger of $224.3 million and net income of $419.3 million, partially offset by
dividend payments of $205.7 million and common stock repurchases of $72.2 million.

The following table provides a comparison of the Company’s and the Bank’s leverage and risk-weighted capital

FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures. As of the end of the period covered by this report, the
Company carried out an evaluation, under the supervision and with the participation of its management, including its
Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its disclosure
controls and procedures. In designing and evaluating the disclosure controls and procedures, management recognizes
that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance
of achieving the desired control objectives, and management was required to apply judgment in evaluating its controls
and procedures. Based on this evaluation, the Company’s Chief Executive Officer and Chief Financial Officer
concluded that the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under
the Exchange Act), were effective as of the end of the period covered by this report.

Changes in internal control over financial reporting. There were no changes in the Company’s internal control
over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during
the quarter ended December 31, 2023, that have materially affected, or are reasonably likely to materially affect, the
Company’s internal control over financial reporting.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of the Company is responsible for establishing and maintaining adequate internal control over
financial reporting. The Company’s internal control over financial reporting is a process designed under the
supervision of the Company’s Chief Executive Officer and Chief Financial Officer to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of the Company’s financial statements for external
purposes in accordance with generally accepted accounting principles.

As of December 31, 2023, management assessed the effectiveness of the Company’s internal control over
financial reporting based on the criteria for effective internal control over financial reporting established in “Internal
Control—Integrated Framework,” issued by the Committee of Sponsoring Organizations (“COSO”) of the Treadway
Commission (“2013 Framework”). Based on the assessment, management determined that the Company maintained
effective internal control over financial reporting as of December 31, 2023.

Deloitte & Touche LLP, the independent registered public accounting firm that audited the consolidated
financial statements of the Company included in this Annual Report on Form 10-K, has issued an attestation report
on the Company’s internal control over financial reporting as of December 31, 2023. The report is included in this
Item under the heading “Report of Independent Registered Public Accounting Firm.”

81

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Prosperity Bancshares, Inc. and subsidiaries

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Prosperity Bancshares, Inc. and subsidiaries
(the “Company”) as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion,
the Company maintained, in all material respects, effective internal control over financial reporting as of December
31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2023, of
the Company and our report dated February 28, 2024, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting
and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying
Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on
the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered
with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal
securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting
was maintained in all material respects. Our audit included obtaining an understanding of internal control over
financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating
effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles. A company’s internal control over financial reporting
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with
generally accepted accounting principles, and that receipts and expenditures of the company are being made only in
accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance
regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that
could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls
may become inadequate because of changes in conditions, or that the degree of compliance with the policies or
procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Prosperity Bancshares, Inc. and subsidiaries

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Prosperity Bancshares, Inc. and subsidiaries
(the “Company”) as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive
income, changes in shareholders' equity, and cash flows, for each of the three years in the period ended December 31,
2023, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial
statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and
2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31,
2023, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2023, based on
criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring
Organizations of the Treadway Commission and our report dated February 28, 2024 expressed an unqualified opinion
on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express
an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered
with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal
securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial statements are free of material
misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material
misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to
those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in
the financial statements. Our audits also included evaluating the accounting principles used and significant estimates
made by management, as well as evaluating the overall presentation of the financial statements. We believe that our
audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial
statements that was communicated or required to be communicated to the audit committee and that (1) relates to
accounts or disclosures that are material to the financial statements and (2) involved our especially challenging,
subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion
on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below,
providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Allowance for Credit Losses - Refer to Note 5 to the financial statements

Critical Audit Matter Description

The allowance for credit losses on loans is an allowance on loans available for estimated losses. All losses are
charged to the allowance when the loss actually occurs or when a determination is made that such a loss is expected
and reasonably estimable. Recoveries are credited to the allowance at the time of recovery.

The Company’s allowance for credit losses on loans consists of two elements: (1) specific valuation allowances
based on expected losses on impaired loans and purchased credit-deteriorated loans (“PCD Loans”); and (2) a general
valuation allowance based on historical lifetime loan loss experience, current economic conditions, reasonable and

89

supportable forecasted economic conditions and other qualitative risk factors both internal and external to the
Company. In making its evaluation, management considers factors such as historical lifetime loan loss experience, the
amount of nonperforming assets and related collateral, the volume, growth and composition of the portfolio, current
economic conditions and reasonable and supportable forecasted economic conditions that may affect the borrower’s
ability to pay and the value of collateral, the evaluation of the portfolio through its internal loan review process and
other relevant factors.

At and for the year-ended December 31, 2023, the allowance for credit losses on loans recorded on the balance
sheet was $332.4 million, and the provision for credit losses recorded on the statement of income was $18.5 million.

We identified the general valuation allowance for loan losses as a critical audit matter because of the significant
amount of judgment required by management when determining the economic factors, reasonable and supportable
forecast, and management adjustments utilized in establishing the reserve. This required a high degree of auditor
judgment and an increased extent of effort, including the need to involve our credit specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the allowance for credit losses – general valuation allowance for loan losses

included the following, among others:

•

•

•

•

•

•

We tested the effectiveness of controls over the (i) written policy in place for the calculation of the general
valuation allowance, (ii) data input to the general valuation allowance calculation and (iii) management’s
review of the adequacy of the general valuation allowance calculation, including the assumptions used in
the calculation.

With the assistance of a credit specialist, we evaluated:

•

•

•

the reasonableness of the classification of the loan types;

the methodology surrounding the reasonableness of economic factors and assumptions used in
the general allowance calculation;

the reasonableness of the logic, statistical validity, and computations of the allowance for credit
losses (“ACL”) calculation.

We evaluated the appropriateness and relevance of the qualitative factors and related quantitative
measures by comparing to external sources.

We tested the accuracy and evaluated the relevance of the historical loss data.

We tested the accuracy of the historical net charge offs.

We tested the arithmetic accuracy of the general valuation allowance calculation.

PROSPERITY BANCSHARES, INC.® AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING
POLICIES

Nature of Operations—Prosperity Bancshares, Inc.® (“Bancshares”) and its subsidiary, Prosperity Bank® (the

“Bank”, collectively referred to as the “Company”), provide retail and commercial banking services.

As of December 31, 2023, the Bank operated 285 full-service banking locations: 65 in the Houston area,
including The Woodlands; 30 in the South Texas area including Corpus Christi and Victoria; 62 in the Dallas/Fort
Worth area; 22 in the East Texas area; 32 in the Central Texas area including Austin and San Antonio; 44 in the West
Texas area including Lubbock, Midland-Odessa, Abilene; Amarillo and Wichita Falls; 16 in the Bryan/College Station
area, 6 in the Central Oklahoma area; and 8 in the Tulsa, Oklahoma area.

Summary of Significant Accounting and Reporting Policies—The accounting and reporting policies of the
Company conform to generally accepted accounting principles (“GAAP”) and the prevailing practices within the
financial services industry. A summary of significant accounting and reporting policies are as follows:

Basis of Presentation—The consolidated financial statements include the accounts of Bancshares and its
subsidiaries. Intercompany transactions have been eliminated in consolidation. Operations are managed and financial
performance is evaluated on a company-wide basis. Accordingly, all of the Company’s banking operations are
considered by management to be aggregated in one reportable operating segment. Because the overall banking
operations comprise the vast majority of the consolidated operations, no separate segment disclosures are presented.

Use of Estimates—The preparation of financial statements in conformity with GAAP requires management to
make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during
the reporting period. Such estimates include, but are not limited to certain fair value measures including the calculation
of stock-based compensation, the valuation of goodwill and available for sale and held to maturity securities and the
calculation of allowance for credit losses. Actual results could differ from these estimates.

Business Combinations—Generally, acquisitions are accounted for under the acquisition method of
accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification
(“ASC”) 805, Business Combinations. A business combination occurs when the Company acquires net assets that
constitute a business and obtains control over that business. Business combinations are effected through the transfer
of consideration consisting of cash and/or common stock and are accounted for using the acquisition method.
Accordingly, the assets and liabilities of the acquired business are recorded at their respective fair values at the
acquisition date. Determining the fair value of assets and liabilities, especially the loan portfolio, is a process involving
significant judgment regarding methods and assumptions used to calculate estimated fair values. Fair values are
subject to refinement for up to one year after the closing date of the acquisition as information relative to closing date
fair values becomes available. The results of operations of an acquired entity are included in the Company’s
consolidated results from acquisition date, and prior periods are not restated.

Securities —The investment securities portfolio is measured for expected credit losses by segregating the
portfolio into two general classifications and applying the appropriate expected credit losses methodology. Investment
securities classified as available for sale or held to maturity are evaluated for expected credit losses under FASB ASC
326, “Financial Instruments – Credit Losses.”

Securities held to maturity are carried at cost, adjusted for the amortization of premiums and the accretion of
discounts. Management has the positive intent and the Company has the ability to hold these assets until their estimated
maturities.

Securities available for sale are carried at fair value. Unrealized gains and losses are excluded from earnings
and reported, net of tax, as a separate component of shareholders’ equity until realized. Securities within the available

96

for sale portfolio may be used as part of the Company’s asset/liability strategy and may be sold in response to changes
in interest rate risk, prepayment risk or other similar economic factors.

For available for sale securities in an unrealized loss position, the amount of the expected credit losses
recognized in earnings depends on whether an entity intends to sell the security or more likely than not will be required
to sell the security before recovery of its amortized cost basis less any current-period credit loss. If an entity intends
to sell or more likely than not will be required to sell the security before recovery of its amortized cost basis less any
current-period credit loss, the expected credit losses will be recognized in earnings equal to the entire difference
between the investment’s amortized cost basis and its fair value at the balance sheet date. If an entity does not intend
to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery
of its amortized cost basis less any current-period loss, the expected credit losses will be separated into the amount
representing the credit-related portion of the impairment loss (“credit loss”) and the noncredit portion of the
impairment loss (“noncredit portion”). The amount of the total expected credit losses related to the credit loss is
determined based on the difference between the present value of cash flows expected to be collected and the amortized
cost basis, and such difference is recognized in earnings. The amount of the total expected credit losses related to the
noncredit portion is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost
basis less the expected credit losses recognized in earnings will become the new amortized cost basis of the investment.
Premiums and discounts are amortized and accreted to operations using the level-yield method of accounting, adjusted
for prepayments as applicable. The specific identification method of accounting is used to compute gains or losses on
the sales of these assets. Interest earned on these assets is included in interest income.

Loans Held for Sale—Loans held for sale are carried at the lower of cost or market value. Premiums, discounts
and loan fees (net of certain direct loan origination costs) on loans held for sale are deferred until the related loans are
sold or repaid. Gains or losses on loan sales are recognized at the time of sale and determined using the specific
identification method.

Loans Held for Investment—Loans originated and held for investment are stated at the principal amount
outstanding, net of unearned fees. The related interest income for multi-payment loans is recognized principally by
the simple interest method; for single payment loans, such income is recognized using the straight-line method.

The Company has two general categories of loans in its portfolio. Loans originated by the Bank and made
pursuant to the Company’s loan policy and procedures in effect at the time the loan was made are referred to as
“originated loans” and loans acquired in a business combination are referred to as “acquired loans.” Acquired loans
are initially recorded at fair value based on a discounted cash flow valuation methodology that considers, among other
things, interest rates, projected default rates, loss given default and recovery rates, with no carryover of any existing
allowance for credit losses. Those acquired loans that are renewed or substantially modified after the date of the
business combination are referred to as “re-underwritten acquired loans.” Modifications are reviewed for
determination of loan modifications made to borrowers experiencing financial difficulty status independently of this
process. In certain instances, acquired loans to one borrower may be combined or otherwise re-originated such that
they are re-categorized as originated loans. Acquired loans with a fair value discount or premium at the date of the
business combination that remained at the reporting date are referred to as “fair-valued acquired loans.” All fair-valued
acquired loans are further categorized into “Non-PCD loans” and “PCD loans” (purchased credit deteriorated loans).
Acquired loans with evidence of more than insignificant credit quality deterioration as of the acquisition date when
compared to the origination date are classified as PCD loans.

The Company estimates the total cash flows expected to be collected from the PCD loans, which include
undiscounted expected principal and interest, using credit risk, interest rate and prepayment risk assessments that
incorporate management’s best estimate of current key assumptions such as default rates, loss severity and payment
speeds. The excess of the undiscounted total cash flows expected to be collected over the fair value of the related PCD
loans represents the accretable yield, which is recognized as interest income based on future cash flows, taking into
account contractual maturities. The difference between the undiscounted contractual principal and the undiscounted
total cash flows expected to be collected is the PCD reserve, which is included in the allowance for credit losses.
Subsequent increases in expected cash flows will result in a recovery of any previously recorded allowance for credit
losses, to the extent applicable. Subsequent decreases in expected cash flows will result in an impairment charge to
the provision for credit losses, resulting in an addition to the allowance for credit losses.

97

A loan disposal, which may include a loan sale, receipt of payment in full from the borrower or foreclosure,
results in removal of the loan from the balance sheet at its allocated carrying amount and accretion of any remaining
fair value discount to income.

Warehouse Purchase Program Loans—All Warehouse Purchase Program loans are collectively evaluated for
impairment and are purchased under several contractual requirements, providing safeguards to the Company. These
safeguards include the requirement that the mortgage originator clients have a takeout commitment or similar
arrangement for each loan. To date, the Company has not experienced a loss on these loans and no allowance for credit
losses has been allocated to them.

Nonrefundable Fees and Costs Associated with Lending Activities—Loan origination fees in excess of the

associated costs are recognized over the life of the related loan as an adjustment to yield using the interest method.

Loan commitment fees and loan origination costs are deferred and recognized as an adjustment of yield by the
interest method over the related loan life or, if the commitment expires unexercised, recognized in income upon
expiration of the commitment.

Nonperforming and Past Due Loans— Included in the nonperforming loan category are loans which have
been categorized by management as nonaccrual because collection of interest is doubtful and loans which have been
modified to provide a reduction in the interest rate or a deferral of interest or principal payments. The Company
generally places a loan on nonaccrual status and ceases accruing interest when the payment of principal or interest is
delinquent for 90 days, or earlier in some cases, unless the loan is in the process of collection and the underlying
collateral fully supports the carrying value of the loan. If the decision is made to continue accruing interest on the
loan, periodic reviews are made to confirm the accruing status of the loan. When a loan is placed on nonaccrual status,
interest accrued but not yet collected prior to the determination as uncollectible is charged to operations. Interest
accrued during prior periods is charged to the allowance for credit losses. Any payments received on nonaccrual loans
are applied first to outstanding principal of the loan amount, next to the recovery of charged-off loan amounts and
finally, any excess is treated as recovery of lost interest. A loan may be returned to accrual status when all the principal
and interest amounts contractually due are brought current and future principal and interest amounts contractually due
are reasonably assured, which is typically evidenced by a sustained period (at least six months) of repayment
performance by the borrower.

Restructured loans are those loans on which concessions in terms have been granted because of a borrower’s

financial difficulty. Interest is generally not accrued on such loans in accordance with the new terms.

Allowance for Credit Losses— The allowance for credit losses is accounted for in accordance with ASU 2016-
13, “Financial Instruments-Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments”
(“CECL”) which replaced the incurred loss methodology with an expected loss methodology that is referred to as the
current expected credit loss methodology. CECL requires a financial asset (or a group of financial assets) measured
at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is
an allowance available for losses on loans and held-to-maturity securities. All losses are charged to the allowance
when the loss actually occurs or when a determination is made that such a loss is likely and can be reasonably
estimated. Recoveries are credited to the allowance at the time of recovery.

Throughout the year, management estimates the level of lifetime losses to determine whether the allowance for
credit losses is adequate to absorb losses in the loan portfolio. Based on these estimates, an amount is charged to the
provision for credit losses and credited to the allowance for credit losses in order to adjust the allowance to a level
determined to be adequate to absorb losses.

In making its evaluation, management considers factors such as historical lifetime loan loss experience, the
amount of nonperforming assets and related collateral, the volume, growth and composition of the portfolio, current
economic conditions and reasonable and supportable forecasted economic conditions that may affect borrower ability
to pay and the value of collateral, the evaluation of the portfolio through its internal loan review process and other
relevant factors.

98

Estimates of credit losses involve an exercise of judgment. While it is possible that in the short term the
Company may sustain losses which are substantial in relation to the allowance for credit losses, it is the judgment of
management that the allowance for credit losses reflected in the consolidated balance sheets is adequate to absorb
expected lifetime losses that may be realized from the loan portfolio as of December 31, 2023.

The Company’s allowance for credit losses consists of two elements: (1) specific valuation allowances based
on expected losses on impaired loans and PCD loans; and (2) a general valuation allowance based on historical lifetime
loan loss experience, current economic conditions, reasonable and supportable forecasted economic conditions, and
other qualitative risk factors both internal and external to the Company.

Non-PCD loans that have deteriorated to an impaired status subsequent to acquisition are evaluated for a
specific reserve on a quarterly basis which, when identified, is added to the allowance for credit losses. The Company
reviews impaired Non-PCD loans on a loan-by-loan basis and determines the specific reserve based on the difference
between the recorded investment in the loan and one of three factors: expected future cash flows, observable market
price or fair value of the collateral. Because essentially all of the Company’s impaired Non-PCD loans have been
collateral-dependent, the amount of the specific reserve historically has been determined by comparing the fair value
of the collateral securing the Non-PCD loan with the recorded investment in such loan. In the future, the Company
will continue to analyze impaired Non-PCD loans on a loan-by-loan basis and may use an alternative measurement
method to determine the specific reserve, as appropriate and in accordance with applicable accounting standards.

PCD loans are monitored individually or on a pooled basis quarterly to assess for changes in expected cash
flows subsequent to acquisition. If a deterioration in cash flows is identified, an increase to the PCD reserves for that
individual loan or pool of loans. PCD loans were recorded at their acquisition date fair values, which were based on
expected cash flows and considers estimates of expected future credit losses. The Company’s estimates of loan fair
values at the acquisition date may be adjusted for a period of up to one year as the Company continues to evaluate its
estimate of expected future cash flows at the acquisition date. If the Company determines that losses arose after the
acquisition date, the additional losses will be reflected as a provision for credit losses.

Accounting for Acquired Loans and the Allowance for Acquired Credit Losses — The Company accounts
for its acquisitions using the acquisition method of accounting. Accordingly, the assets, including loans, and liabilities
of the acquired entity were recorded at their fair values at the acquisition date. These fair value estimates associated
with acquired loans, and based on a discounted cash flow model, include estimates related to market interest rates and
undiscounted projections of future cash flows that incorporate expectations of prepayments and the amount and timing
of principal, interest and other cash flows, as well as any shortfalls thereof. For further discussion of the Company’s
acquisition and loan accounting, see Note 5 to the consolidated financial statements.

Allowance for Credit Losses on Off-Balance Sheet Credit Exposures — The allowance for credit losses on
off-balance sheet credit exposures estimates expected credit losses over the contractual period in which there is
exposure to credit risk via a contractual obligation to extend credit, except when an obligation is unconditionally
cancellable by the Company. The allowance is adjusted by provisions for credit losses charged to earnings that increase
the allowance, or by provision releases returned to earnings that decrease the allowance. The estimate includes
consideration of the likelihood that funding will occur and an estimate of expected credit losses on the commitments
expected to fund. The estimate of commitments expected to fund is affected by historical analysis of utilization rates.
The expected credit loss rates applied to the commitments expected to fund are affected by the general valuation
allowance utilized for outstanding balances with the same underlying assumptions and drivers.

Premises and Equipment—Premises and equipment are carried at cost less accumulated depreciation.
Depreciation expense is computed principally using the straight-line method over the estimated useful lives of the
assets which range from one to 39 years. Leasehold improvements are amortized using the straight-line method over
the periods of the leases or the estimated useful lives, whichever is shorter.

99

Derivative Financial Instruments—The Company has interest rate swaps with certain commercial customers
who wished to obtain a loan at a fixed rate. The Company enters into an interest rate swap with the customer while at
the same time entering into an offsetting interest rate swap with another financial institution. In connection with each
swap transaction, the Company agrees to pay interest to the borrowing customer on a notional amount at a variable
interest rate and receives interest from the customer on the same notional amount at a fixed interest rate. At the same
time, the Company agrees to pay another financial institution a similar fixed interest rate on the same notional amount
and receive substantially the same variable interest rate on the same notional amount. The transaction allows the
customer to effectively convert a variable-rate loan to a fixed-rate. Because the Company acts solely as an intermediary
for its customer, changes in the fair value of the underlying derivative contracts largely offset each other and do not
significantly impact the Company’s results of operations.

The Company has interest rate lock commitments and forward mortgage-backed securities trades. In the normal
course of business, the Company enters into interest rate lock commitments with consumers to originate mortgage
loans at a specified interest rate. These commitments, which contain fixed expiration dates, offer the borrower an
interest rate guarantee provided the loan meets underwriting guidelines and closes within the timeframe established
by the Company. The Company manages the changes in fair value associated with changes in interest rates related to
interest rate lock commitments by using forward sold commitments known as forward mortgage-backed securities
trades. These instruments are typically entered into at the time the interest rate lock commitment is made.

These financial instruments are not designated as hedging instruments and are used for asset and liability
management and commercial customers’ financing needs. All derivatives are carried at fair value in either other assets
or other liabilities and all related cash flows are reported in the operating section of the consolidated statements of
cash flows.

Goodwill —Goodwill is annually assessed for impairment or when events or changes in circumstances indicate

that the carrying amount of the asset may not be recoverable.

Under ASC Topic 350-20, “Intangibles—Goodwill and Other—Goodwill” companies have the option to first
assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less
than its carrying amount as a basis for determining the need to perform step one of the annual test for goodwill
impairment. An entity has an unconditional option to bypass the qualitative assessment for any reporting unit in any
period and proceed directly to performing the first step of the goodwill impairment test. An entity may resume
performing the qualitative assessment in any subsequent period. If the estimated fair value of the reporting unit exceeds
its carrying value, goodwill of the reporting unit is not impaired.

Amortization of Core Deposit Intangibles—Core deposit intangibles are being amortized on a non-pro rata

basis over an estimated life of 10 to 15 years.

Income Taxes— The Company files a consolidated federal income tax return and consolidated state returns in
Oklahoma, Colorado, New Mexico and New York. For the year ended December 31, 2023, the Bank will also file
state returns in Arkansas, Florida, Georgia, Idaho, North Carolina, Pennsylvania, Tennessee and Washington.
In
addition, the Company files a Combined Texas Franchise Tax Report.

Deferred tax assets and liabilities are recognized for the estimated tax consequences attributable to differences
between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and
are recorded net to other assets on the Company’s consolidated balance sheets. The Company records uncertain tax
positions in accordance with ASC Topic 740 “Income Taxes” on the basis of a two-step process whereby (1) the
Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the
technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold,
the Company recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon
ultimate settlement with the related tax authority.

Realization of net deferred tax assets is based upon the level of historical income and on estimates of future
taxable income. Although realization is not assured, management believes it is more likely than not that all of the net
deferred tax assets will be realized.

100

Stock-Based Compensation—The Company accounts for stock-based employee compensation plans using
the fair value-based method of accounting. The expense associated with stock-based compensation is recognized over
the vesting period of each individual arrangement. The fair value of restricted stock awards is based on the current
market price on the date of grant.

Cash and Cash Equivalents—For purposes of reporting cash flows, cash and cash equivalents include cash

and due from banks as well as federal funds sold that mature in three days or less.

Earnings Per Common Share—Basic earnings per common share are calculated using the two-class method.
The two-class method provides that unvested share-based payment awards that contain nonforfeitable rights to
dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the
computation of basic earnings per share.

Diluted earnings per common share is computed using the weighted-average number of shares determined for
the basic earnings per common share computation plus the potential dilution that could occur if securities or other
contracts to issue common stock were exercised or converted into common stock using the treasury stock method.

The following table illustrates the computation of basic and diluted earnings per share:

New Accounting Standards

Accounting Standards Updates (“ASU”)

ASU 2023-09, Income Taxes (Topic 740): Improvements to Income. ASU No. 2023-09 focuses on the rate
reconciliation and income taxes paid. ASU No. 2023-09 requires a public business entity to disclose, on an annual
basis, a tabular rate reconciliation using both percentages and currency amounts, broken out into specified categories
with certain reconciling items further broken out by nature and jurisdiction to the extent those items exceed a specified
threshold. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by
federal, state/local, and foreign and by jurisdiction if the amount is at least 5% of total income tax payments, net of
refunds received. For public business entities the new standard is effective for annual periods beginning after
December 15, 2024, with early adoption permitted. An entity may apply the amendments in this ASU prospectively
by providing the revised disclosures for the period ending December 31, 2025 and continuing to provide the pre-ASU
disclosures for the prior periods, or may apply the amendments retrospectively by providing the revised disclosures
for all period presented. The Company does not expect ASU 2023-09 to have an impact on its financial statements.

101

ASU 2023-07, Segment Reporting (Topic 280) - Improvement to Reportable Segment Disclosures. ASU 2023-
07 amends the disclosure requirements related to segment reporting primarily through enhanced disclosure about
significant segment expenses and by requiring disclosure of segment information on an annual and interim basis. ASU
2023-07 is effective January 1, 2024 and the Company does not expect ASU 2023-07 to have a significant impact on
its financial statements.

ASU 2023-06, Disclosure Improvements—Codification Amendments in Response to the SEC’s Disclosure
Update and Simplification Initiative. ASU 2023-06 amends the FASB Accounting Standards Codification to
incorporate certain disclosure requirements from SEC Release No. 33-10532 - Disclosure Update and Simplification
that was issued in 2018. The effective date for each amendment will be the date on which the SEC’s removal of that
related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. The
Company does not expect ASU 2023-06 to have a significant impact on its financial statements.

ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage
Disclosures. The amendments in ASU 2022-02 eliminated the accounting guidance for troubled debt restructurings
and enhanced disclosures for certain loan refinancing and restructurings to borrowers experiencing financial difficulty.
This guidance was applied on a prospective basis. Additionally, ASU 2022-02 requires entities to disclose current-
period gross charge-offs by year of origination. ASU 2022-02 became effective for the Company on January 1, 2023
and did not have a significant impact on the Company’s financial statements.

ASU 2020-04, Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform on Financial
Reporting – ASC Topic 848. ASU 2020-04 became effective for the Company on January 1, 2022 and provides
optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other
transactions affected by the anticipated transition away from the London Inter-Bank Offered Rate (“LIBOR”) toward
new interest rate benchmarks. ASU 2020-04 was effective upon issuance. In addition, the FASB issued ASU 2022-06
-Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which extends the period of time
preparers can utilize the reference rate reform relief guidance provided by ASU 2020-04 from December 31, 2022 to
December 31, 2024. ASU 2022-06 was effective upon issuance and did not change the core principles in ASU 2020-
04. Prior to the end of 2021, the Company began transitioning away from LIBOR to the Secured Overnight Financing
Rate (“SOFR”) or other alternative variable rate indexes for its interest-rate swaps and loans historically using LIBOR
as an index. As of December 31, 2023, the Company's interest rate swaps and loan portfolio used SOFR as the index
rate. As of December 31, 2022, LIBOR was used as an index rate for approximately 88.2% of the Company’s interest-
rate swaps and approximately 1.5% of the Company’s loan portfolio. The adoption of ASU 2020-04 did not have a
significant impact on the Company’s financial statements.

2. ACQUISITIONS

Acquisitions are an integral part of the Company’s growth strategy. All acquisitions were accounted for using
the acquisition method of accounting. Accordingly, the assets and liabilities of the acquired entities were recorded at
their fair values at the acquisition date. The excess of the purchase price over the estimated fair value of the net assets
for tax-free acquisitions was recorded as goodwill, none of which is deductible for tax purposes. The excess of the
purchase price over the estimated fair value of the net assets for taxable acquisitions was also recorded as goodwill
and is deductible for tax purposes. The identified core deposit intangibles for each acquisition are being amortized
using a non-pro rata basis over an estimated life of 10 to 15 years. The results of operations for each acquisition have
been included in the Company’s consolidated financial results beginning on the respective acquisition date.

The measurement period for the Company to determine the fair values of acquired identifiable assets and
assumed liabilities will end at the earlier of (1) twelve months from the date of the acquisition or (2) as soon as the
Company receives the information it was seeking about facts and circumstances that existed as of the acquisition date
or learns that more information is not obtainable.

102

Recent Acquisition

Merger of First Bancshares of Texas, Inc. (“First Bancshares”) — Effective May 1, 2023, the Company
completed the Merger of First Bancshares into Bancshares and the subsequent merger of its wholly owned subsidiary
FirstCapital Bank of Texas, N.A. (“FirstCapital Bank”), into the Bank. FirstCapital Bank operated 16 full-service
banking offices in six different markets in West, North and Central Texas areas, including its main office in Midland,
and banking offices in Midland, Lubbock, Amarillo, Wichita Falls, Burkburnett, Byers, Henrietta, Dallas, Horseshoe
Bay, Marble Falls and Fredericksburg, Texas. As of March 31, 2023, First Bancshares, on a consolidated basis,
reported total assets of $2.14 billion, total loans of $1.65 billion and total deposits of $1.71 billion. The acquisition
was not considered significant to the Company’s financial statements and therefore pro forma financial data and
related disclosures are not included.

Pursuant to the terms of the definitive agreement, Bancshares issued 3,583,370 shares of its common stock and
approximately $91.5 million in cash for all outstanding shares of First Bancshares. As of December 31, 2023, the
Company recognized goodwill of $164.5 million, which does not include all the subsequent fair value adjustments
that have not yet been finalized. Goodwill represents the excess of the total purchase price paid over the fair value of
the assets acquired, net of the fair value of liabilities assumed. During the second quarter of 2023, the Company
completed the operational conversion of FirstCapital Bank.

Pending Acquisition

Pending Merger of Lone Star State Bancshares, Inc. (“Lone Star”) — On October 11, 2022, Bancshares and
Lone Star jointly announced the signing of a definitive merger agreement whereby Lone Star, the parent company of
Lone Star State Bank of West Texas (“Lone Star Bank”), will merge with and into Bancshares. Lone Star Bank
operates five banking offices in the West Texas area, including its main office in Lubbock, and one banking center in
each of Brownfield, Midland, Odessa and Big Spring, Texas. As of December 31, 2023, Lone Star, on a consolidated
basis, reported total assets of $1.37 billion, total loans of $1.08 billion and total deposits of $1.21 billion.

Under the terms of the merger agreement, Bancshares will issue 2,376,182 shares of its common stock plus
$64.1 million in cash for all outstanding shares of Lone Star capital stock, subject to certain conditions and potential
adjustments. Based on the closing price of Bancshares’ common stock of $69.27 on October 7, 2022, the total
consideration was valued at approximately $228.7 million. The transaction is subject to customary closing conditions,
including the receipt of regulatory approvals. The shareholders of Lone Star approved the transaction on March 28,
2023.

Acquired Loans

Acquired loans were preliminarily recorded at fair value based on a discounted cash flow valuation methodology
that considers, among other things, interest rates, projected default rates, loss given default, and recovery rates.
Projected default rates, loss given default, and recovery rates for purchased credit deteriorated (“PCD”) loans primarily
impact the related allowance, as opposed to the fair value mark. During the valuation process, the Company identified
PCD and Non-PCD loans in the acquired loan portfolios. Loans acquired with evidence of credit quality deterioration
since origination as of the acquisition date were accounted for as PCD. PCD loan identification considers the following
factors: payment history and past due status, debt service coverage, loan grading, collateral values and other factors
that may indicate deterioration of credit quality as of the acquisition date when compared to the origination date. Non-
PCD loan identification considers the following factors: account types, remaining terms, annual interest rates or
coupons, current market rates, interest types, past delinquencies, timing of principal and interest payments, loan to
value ratios, loss exposures and remaining balances. Accretion of purchased discounts on PCD and Non-PCD loans
will be recognized based on payment structure and the contractual maturity of individual loans.

The investment securities portfolio is measured for expected credit losses by segregating the portfolio into two
general classifications and applying the appropriate expected credit losses methodology. Investment securities
classified as available for sale or held to maturity are evaluated for expected credit losses under FASB ASC Topic
326, “Financial Instruments – Credit Losses.”

Available for sale securities. For available for sale securities in an unrealized loss position, the amount of the
expected credit losses recognized in earnings depends on whether an entity intends to sell the security or more likely
than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit
loss. If an entity intends to sell or more likely than not will be required to sell the security before recovery of its
amortized cost basis less any current-period credit loss, the expected credit losses will be recognized in earnings equal
to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If an
entity does not intend to sell the security and it is not more likely than not that the entity will be required to sell the
security before recovery of its amortized cost basis less any current-period loss, the expected credit losses will be
separated into the amount representing the credit-related portion of the impairment loss (“credit loss”) and the
noncredit portion of the impairment loss (“noncredit portion”). The amount of the total expected credit losses related
to the credit loss is determined based on the difference between the present value of cash flows expected to be collected
and the amortized cost basis and such difference is recognized in earnings. The amount of the total expected credit
losses related to the noncredit portion is recognized in other comprehensive income, net of applicable taxes. The
previous amortized cost basis less the expected credit losses recognized in earnings will become the new amortized
cost basis of the investment.

As of December 31, 2023, management does not have the intent to sell any of the securities classified as
available for sale before a recovery of cost. In addition, management believes it is more likely than not that the
Company will not be required to sell any of its investment securities before a recovery of cost. The unrealized losses
are largely due to changes in market interest rates and spread relationships since the time the underlying securities
were purchased. The fair value is expected to recover as the securities approach their maturity date or repricing date
or if market yields for such investments decline. Management does not believe any of the securities are impaired due
to reasons of credit quality. Accordingly, as of December 31, 2023, management believes that there is no potential for
credit losses on available for sale securities.

Held to maturity securities. The Company’s held to maturity investments include mortgage-related bonds
issued by either the Government National Mortgage Corporation (“Ginnie Mae”), Federal National Mortgage
Association (“Fannie Mae”) or Federal Home Loan Mortgage Corporation (“Freddie Mac”). Ginnie Mae issued
securities are explicitly guaranteed by the U.S. government, while Fannie Mae and Freddie Mac issued securities are
fully guaranteed by those respective United States government-sponsored agencies, and conditionally guaranteed by
the full faith and credit of the United States. The Company’s held to maturity securities also include taxable and tax-
exempt municipal securities issued primarily by school districts, utility districts and municipalities located in Texas.
The Company’s investment in municipal securities is exposed to credit risk. The securities are highly rated by major
rating agencies and regularly reviewed by management. A significant portion are guaranteed or insured by either the
Texas Permanent School Fund, Assured Guaranty or Build America Mutual. As of December 31, 2023, the Company’s

106

municipal securities represent 0.9% of the securities portfolio. Management has the ability and intent to hold the
securities classified as held to maturity until they mature, at which time the Company will receive full value for the
securities. Accordingly, as of December 31, 2023, management believes that there is no potential for material credit
losses on held to maturity securities.

Securities with unrealized losses segregated by length of time such securities have been in a continuous loss

position were as follows:

Loan Origination/Risk Management. The Company has certain lending policies and procedures in place that are
designed to maximize loan income within an acceptable level of risk. Management reviews and approves these policies
and procedures on a regular basis. A reporting system supplements the review process by providing management with
frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and non-
performing and potential problem loans. Diversification in the loan portfolio is a means of managing risk associated
with fluctuations in economic conditions. Loans to borrowers with aggregate debt relationships over $1.0 million and
below $5.0 million are evaluated and acted upon on a daily basis by two of the company-wide loan concurrence
officers. Loans to borrowers with aggregate debt relationships above $5.0 million are evaluated and acted upon by an
officers’ loan committee that meets weekly.

The Company maintains an independent loan review department that reviews and validates the credit risk
program on a periodic basis. Results of these reviews are presented to management. The loan review process
complements and reinforces the risk identification and assessment decisions made by lenders and credit personnel, as
well as the Company’s policies and procedures.

(i) Commercial and Industrial Loans. In nearly all cases, the Company’s commercial loans are made in the
Company’s market areas and are underwritten based on the borrower's ability to service the debt from the conversion
of working assets or cash flow. Working capital loans are primarily collateralized by short-term assets whereas term
loans are primarily collateralized by long-term assets. As a general practice, term loans are secured by any available
real estate, equipment or other assets owned by the borrower. Both working capital and term loans are typically
supported by a personal guaranty of a principal. In general, commercial loans involve more credit risk than residential
mortgage loans and commercial mortgage loans and, therefore, usually yield a higher return. The increased risk in
commercial loans is due to the type of collateral securing these loans as well as the expectation that commercial loans
generally will be serviced principally from the operations of the business, and those operations may not be successful.
Historical trends have shown these types of loans to have higher delinquencies than mortgage loans. As a result of
these additional complexities, variables and risks, commercial loans require more thorough underwriting and servicing
than other types of loans.

(ii) Commercial Real Estate. The Company makes commercial real estate loans collateralized by owner-
occupied and nonowner-occupied real estate to finance the purchase of real estate. The Company’s commercial real
estate loans are collateralized by first liens on real estate, typically have variable interest rates (or five year or less
fixed rates) and amortize over a 15- to 25-year period. Payments on loans secured by nonowner-occupied properties
are often dependent on the successful operation or management of the properties. Accordingly, repayment of these
loans may be subject to adverse conditions in the real estate market or the economy to a greater extent than other types
of loans. The Company seeks to minimize these risks in a variety of ways, including giving careful consideration of
the property’s operating history, future operating projections, current and projected occupancy, location and physical
condition in connection with underwriting these loans. The underwriting analysis also includes credit verification,
analysis of global cash flow, collateral valuation and a review of the financial condition of the borrower and guarantor.
Loans to hotels and restaurants are primarily included in commercial real estate loans.

(iii) 1-4 Family Residential Loans. The Company’s lending activities also include the origination of 1-4 family
residential mortgage loans (including home equity loans) collateralized by owner-occupied and nonowner-occupied
residential properties located in the Company’s market areas. The Company offers a variety of mortgage loan portfolio
products which generally are amortized over five to 30 years. Loans collateralized by 1-4 family residential real estate
generally have been originated in amounts of no more than 89% of appraised value. The Company requires mortgage
title insurance, as well as hazard, wind and/or flood insurance as appropriate. The Company prefers to retain residential
mortgage loans for its own account rather than selling them into the secondary market. By doing so, the Company
incurs interest rate risk as well as the risks associated with non-payments on such loans. The Company’s mortgage
department also offers a variety of mortgage loan products which are generally amortized over 30 years, including
FHA and VA loans, which are sold to secondary market investors.

109

(iv) Construction, Land Development and Other Land Loans. The Company makes loans to finance the
construction of residential and nonresidential properties. Construction loans generally are collateralized by first liens
on real estate and have variable interest rates. The Company conducts periodic inspections, either directly or through
an agent, prior to approval of periodic draws on these loans. Underwriting guidelines similar to those described above
are also used in the Company’s construction lending activities, with heightened analysis of construction and/or
development costs. Construction loans involve additional risks attributable to the fact that loan funds are advanced
upon the security of a project under construction, and the project is of uncertain value prior to its completion. Because
of uncertainties inherent in estimating construction costs, the market value of the completed project and the effects of
governmental regulation on real property, it can be difficult to accurately evaluate the total funds required to complete
a project and the related loan to value ratio. As a result of these uncertainties, construction lending often involves the
disbursement of substantial funds with repayment dependent, in part, on the success of the ultimate project rather than
the ability of a borrower or guarantor to repay the loan. If the Company is forced to foreclose on a project prior to
completion, the Company may not be able to recover all of the unpaid portion of the loan. In addition, the Company
may be required to fund additional amounts to complete a project and may have to hold the property for an
indeterminate period of time. Although the Company has underwriting procedures designed to identify what it believes
to be acceptable levels of risks in construction lending, these procedures may not prevent losses from the risks
described above.

(v) Warehouse Purchase Program. The Warehouse Purchase Program allows unaffiliated mortgage originators
(“Clients”) to close 1-4 family real estate loans in their own name and manage their cash flow needs until the loans
are sold to investors. The Company's Clients are strategically targeted for their experienced management teams and
analyzed for the expected profitability of each Client’s business model over the long term. The Clients are located
across the U.S. and originate mortgage loans primarily through traditional retail and/or wholesale business models
using underwriting standards consistent with the United States government-sponsored enterprises, “Agencies” such
as Fannie Mae, the private investors to which the mortgage loans are ultimately sold and the mortgage insurers.

Although not subject to any legally binding commitment, when the Company makes a purchase decision, it
acquires a 100% participation interest in the mortgage loans originated by its Clients. Individual mortgage loans are
warehoused in the Company’s portfolio only for a short duration, averaging less than 30 days. When instructed by a
Client that a warehoused loan has been sold to an investor, the Company delivers the note to the investor that pays the
Company, which in turn remits the net sales proceeds to the Client.

(vi) Agriculture Loans. The Company provides agriculture loans for short-term livestock and crop production,
including rice, cotton, milo and corn, farm equipment financing and agriculture real estate financing. The Company
evaluates agriculture borrowers primarily based on their historical profitability, level of experience in their particular
industry segment, overall financial capacity and the availability of secondary collateral to withstand economic and
natural variations common to the industry. Because agriculture loans present a higher level of risk associated with
events caused by nature, the Company routinely makes on-site visits and inspections in order to identify and monitor
such risks.

(vii) Consumer Loans. Consumer loans made by the Company include direct “A”-credit automobile loans,
recreational vehicle loans, boat loans, home improvement loans, personal loans (collateralized and uncollateralized)
and deposit account collateralized loans. The terms of these loans typically range from 12 to 180 months and vary
based upon the nature of collateral and size of loan. Generally, consumer loans entail greater risk than do real estate
secured loans, particularly in the case of consumer loans that are unsecured or collateralized by rapidly depreciating
assets such as automobiles. In such cases, any repossessed collateral for a defaulted consumer loan may not provide
an adequate source of repayment for the outstanding loan balance. The remaining deficiency often does not warrant
further substantial collection efforts against the borrower beyond obtaining a deficiency judgment. In addition,
consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to
be adversely affected by job loss, divorce, illness, personal bankruptcy or death. Furthermore, the application of
various federal and state laws may limit the amount which can be recovered on such loans.

110

Loan Maturities. The contractual maturity ranges of the Company’s loan portfolio, excluding loans held for sale
of $5.7 million and Warehouse Purchase Program Loans of $822.2 million, by type of loan and the amount of such
loans with predetermined interest rates and variable rates in each maturity range as of December 31, 2023 are
summarized in the following table. Contractual maturities are based on contractual amounts outstanding and do not
include loan purchase discounts of $27.9 million.

Concentrations of Credit. Most of the Company’s lending activity occurs within the states of Texas and
Oklahoma. Commercial real estate loans, 1-4 family residential loans and construction, land development and other
land loans make up 83.0% and 80.3% of the Company’s total loan portfolio, excluding Warehouse Purchase Program
loans, at December 31, 2023 and 2022, respectively. As of December 31, 2023 and 2022, excluding Warehouse
Purchase Program loans, there were no concentrations of loans related to any single industry in excess of 10% of total
loans.

Related Party Loans. As of December 31, 2023 and 2022, loans outstanding to directors, officers and their

Nonperforming Assets and Nonaccrual and Past Due Loans. The Company has several procedures in place to
assist it in maintaining the overall quality of its loan portfolio. The Company has established underwriting guidelines
to be followed by its officers, including requiring appraisals on loans collateralized by real estate. The Company also
monitors its delinquency levels for any negative or adverse trends. Nevertheless, the Company’s loan portfolio could
become subject to increasing pressures from deteriorating borrower credit due to general economic conditions.

The Company generally places a loan on nonaccrual status and ceases accruing interest when the payment of
principal or interest is delinquent for 90 days, or earlier in some cases unless the loan is in the process of collection
and the underlying collateral fully supports the carrying value of the loan. A loan may be returned to accrual status
when all the principal and interest amounts contractually due are brought current and future principal and interest
amounts contractually due are reasonably assured, which is typically evidenced by a sustained period (at least six
months) of repayment performance by the borrower.

With respect to potential problem loans, an evaluation of the borrower’s overall financial condition is made,
together with an appraisal for loans collateralized by real estate, to determine the need, if any, for possible write downs
or appropriate additions to the allowance for credit losses.

Credit Quality Indicators. As part of the ongoing monitoring of the credit quality of the Company’s loan
portfolio and methodology for calculating the allowance for credit losses, management assigns and tracks loan grades
to be used as credit quality indicators.

The following is a general description of the loan grades used:

Grade 1—Credits in this category have risk potential that is virtually nonexistent. These loans may be secured
by insured certificates of deposit, insured savings accounts, U.S. Government securities and highly rated municipal
bonds.

Grade 2—Credits in this category are of the highest quality. These borrowers represent top-rated companies
and individuals with unquestionable financial standing with excellent global cash flow coverage, net worth, liquidity
and collateral coverage.

Grade 3—Credits in this category are not immune from risk but are well protected by the collateral and paying
capacity of the borrower. These loans may exhibit a minor unfavorable credit factor, but the overall credit is
sufficiently strong to minimize the possibility of loss.

Grade 4—Credits in this category are considered to be of acceptable credit quality with moderately greater risk
than Grade 3 and receiving closer monitoring. Loans in this category have sources of repayment that remain sufficient
to preclude a larger than normal probability of default and secondary sources are likewise currently of sufficient
quantity, quality, and liquidity to protect the Company against loss of principal and interest. These borrowers have
specific risk factors, but the overall strength of the credit is acceptable based on other mitigating credit and/or collateral
factors and can repay the debt in the normal course of business.

Grade 5—Credits in this category constitute an undue and unwarranted credit risk; however, the factors do not
rise to a level of substandard. These credits have potential weaknesses and/or declining trends that, if not corrected,
could expose the Company to risk at a future date. These loans are monitored on the Company’s internally-generated
watch list and evaluated on a quarterly basis.

Grade 6—Credits in this category are considered “substandard” but “non-impaired” loans in accordance with
regulatory guidelines. Loans in this category have well-defined weakness that, if not corrected, could make default of
principal and interest possible. Loans in this category are still accruing interest and may be dependent upon secondary
sources of repayment and/or collateral liquidation.

Grade 7—Credits in this category are deemed “substandard” and “impaired” pursuant to regulatory guidelines.
As such, the Company has determined that it is probable that less than 100% of the contractual principal and interest
will be collected. These loans are individually evaluated for a specific reserve and will typically have the accrual of
interest stopped.

Grade 8—Credits in this category include “doubtful” loans in accordance with regulatory guidance. Such loans
are no longer accruing interest and factors indicate a loss is imminent. These loans are also deemed “impaired.” While
a specific reserve may be in place while the loan and collateral are being evaluated these loans are typically charged
down to an amount the Company estimates is collectible.

Grade 9—Credits in this category are deemed a “loss” in accordance with regulatory guidelines and have been
charged off or charged down. The Company may continue collection efforts and may have partial recovery in the
future.

(1) Includes $5.7 million of residential mortgage loans held for sale at December 31, 2023.

Allowance for Credit Losses on Loans. The allowance for credit losses is adjusted through charges to earnings
in the form of a provision for credit losses. Management has established an allowance for credit losses which it believes
is adequate as of December 31, 2023 for estimated losses in the Company’s loan portfolio. The amount of the
allowance for credit losses on loans is affected by the following: (1) charge-offs of loans that occur when loans are
deemed uncollectible and decrease the allowance, (2) recoveries on loans previously charged off that increase the
allowance, (3) provisions for credit losses charged to earnings that increase the allowance, and (4) provision releases
returned to earnings that decrease the allowance. Based on an evaluation of the loan portfolio and consideration of
the factors listed below, management presents a quarterly review of the allowance for credit losses to the Bank’s Board
of Directors, indicating any change in the allowance since the last review and any recommendations as to adjustments
in the allowance. Although management believes it uses the best information available to make determinations with
respect to the allowance for credit losses, future adjustments may be necessary if economic conditions or borrower
performance differ from the assumptions used in making the initial determinations.

The Company’s allowance for credit losses on loans consists of two components: (1) a specific valuation
allowance based on expected losses on specifically identified loans and (2) a general valuation allowance based on
historical lifetime loan loss experience, current economic conditions, reasonable and supportable forecasted economic
conditions and other qualitative risk factors both internal and external to the Company.

117

In setting the specific valuation allowance, the Company follows a loan review program to evaluate the credit
risk in the total loan portfolio and assigns risk grades to each loan. Through this loan review process, the Company
maintains an internal list of impaired loans which, along with the delinquency list of loans, helps management assess
the overall quality of the loan portfolio and the adequacy of the allowance for credit losses. All loans that have been
identified as impaired are reviewed on a quarterly basis in order to determine whether a specific reserve is required.
For certain impaired loans, the Company allocates a specific loan loss reserve primarily based on the value of the
collateral securing the impaired loan in accordance with ASC Topic 326-20, “Financial Instruments – Credit Losses.”
The specific reserves are determined on an individual loan basis. Loans for which specific reserves are provided are
excluded from the general valuation allowance described below.

In connection with this review of the loan portfolio, the Company considers risk elements attributable to

particular loan types or categories in assessing the quality of individual loans. Some of the risk elements include:

•

•

•

•

•

•

•

including a
for 1-4 family residential mortgage loans,
consideration of the debt to income ratio and employment and income stability, the loan to value ratio,
and the age, condition and marketability of collateral;

the borrower’s ability to repay the loan,

for commercial real estate loans and multifamily residential loans, the debt service coverage ratio (income
from the property in excess of operating expenses compared to loan payment requirements), operating
results of the owner in the case of owner-occupied properties, the loan to value ratio, the age and condition
of the collateral and the volatility of income, property value and future operating results typical of
properties of that type;

for construction, land development and other land loans, the perceived feasibility of the project including
the ability to sell developed lots or improvements constructed for resale or the ability to lease property
constructed for lease, the quality and nature of contracts for presale or prelease, if any, experience and
ability of the developer and loan to value ratio;

for commercial and industrial loans, the operating results of the commercial, industrial or professional
enterprise, the borrower’s business, professional and financial ability and expertise, the specific risks and
volatility of income and operating results typical for businesses in that category and the value, nature and
marketability of collateral;

for the Warehouse Purchase Program, the capitalization and liquidity of the mortgage banking client, the
operating experience, the Client’s satisfactory underwriting of purchased loans and the consistent
timeliness by the Client of loan resale to investors;

for agricultural real estate loans, the experience and financial capability of the borrower, projected debt
service coverage of the operations of the borrower and loan to value ratio; and

for non-real estate agricultural loans, the operating results, experience and financial capability of the
borrower, historical and expected market conditions and the value, nature and marketability of collateral.

In addition, for each category, the Company considers secondary sources of income and the financial strength

and credit history of the borrower and any guarantors.

In determining the amount of the general valuation allowance, management considers factors such as historical
lifetime loan loss experience, concentration risk of specific loan types, the volume, growth and composition of the
Company’s loan portfolio, current economic conditions and reasonable and supportable forecasted economic
conditions that may affect borrower ability to pay and the value of collateral, the evaluation of the Company’s loan
portfolio through its internal loan review process, other qualitative risk factors both internal and external to the
Company and other relevant factors in accordance with ASC Topic 326, “Financial Instruments – Credit Losses.”
Historical lifetime loan loss experience is determined by utilizing an open-pool (“cumulative loss rate”) methodology.
Adjustments to the historical lifetime loan loss experience are made for differences in current loan pool risk
characteristics such as portfolio concentrations, delinquency, non-accrual, and watch list levels, as well as changes in
current and forecasted economic conditions such as unemployment rates, property and collateral values, and other
indices relating to economic activity. The utilization of reasonable and supportable forecasts includes an immediate
reversion to lifetime historical loss rates. Based on a review of these factors for each loan type, the Company applies
an estimated percentage to the outstanding balance of each loan type, excluding any loan that has a specific reserve.

118

Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in
other categories.

A change in the allowance for credit losses can be attributable to several factors, most notably (1) specific
reserves identified for impaired loans and PCD loans, (2) historical lifetime credit loss information, (3) changes in
current and forecasted environmental factors and (4) growth in the balance of loans.

Changes in the Company’s asset quality are reflected in the allowance in several ways. Specific reserves that
are calculated on a loan-by-loan basis and the qualitative assessment of all other loans reflect current changes in the
credit quality of the loan portfolio. Historical lifetime credit losses, on the other hand, are based on an open-pool
(“cumulative loss rate”) methodology, which is then applied to estimate lifetime credit losses in the loan portfolio. A
deterioration in the credit quality of the loan portfolio in the current period would increase the historical lifetime loss
rate to be applied in future periods, just as an improvement in credit quality would decrease the historical lifetime loss
rate.

The allowance for credit losses is further determined by the size of the loan portfolio subject to the allowance
methodology and environmental factors that include Company-specific risk indicators and general economic
conditions, both of which are constantly changing. The Company evaluates the economic and portfolio-specific factors
on a quarterly basis to determine a qualitative component of the general valuation allowance. The factors include
current economic metrics, reasonable and supportable forecasted economic metrics, business conditions, delinquency
trends, credit concentrations, nature and volume of the portfolio and other adjustments for items not covered by
specific reserves and historical lifetime loss experience. Management’s assessment of qualitative factors is a
statistically based approach to determine the loss rate adjustment associated with such factors. Based on the
Company’s actual historical lifetime loan loss experience relative to economic and loan portfolio-specific factors at
the time the losses occurred, management is able to identify the expected level of lifetime losses as of the date of
measurement. The correlation of historical loss experience with current and forecasted economic conditions provides
an estimate of lifetime losses that has not been previously factored into the general valuation allowance by the
determination of specific reserves and lifetime historical losses. Additionally, the Company considers qualitative
factors not easily quantified and the possibility of model imprecision.

Utilizing the aggregation of specific reserves, historical

loss experience and a qualitative component,

management is able to determine the valuation allowance to reflect the full lifetime loss.

The Company accounts for its acquisitions using the acquisition method of accounting. Accordingly, the assets,
including loans, and liabilities of the acquired entity were recorded at their fair values at the acquisition date. These
fair value estimates associated with acquired loans, and based on a discounted cash flow model, include estimates
related to market interest rates and undiscounted projections of future cash flows that incorporate expectations of
prepayments and the amount and timing of principal, interest and other cash flows, as well as any shortfalls thereof.

Non-PCD loans that were not deemed impaired subsequent to the acquisition date are considered non-impaired
and are evaluated as part of the general valuation allowance. Non-PCD loans that have deteriorated to an impaired
status subsequent to acquisition are evaluated for a specific reserve on a quarterly basis which, when identified, is
added to the allowance for credit losses. The Company reviews impaired Non-PCD loans on a loan-by-loan basis and
determines the specific reserve based on the difference between the recorded investment in the loan and one of three
factors: expected future cash flows, observable market price or fair value of the collateral. Because essentially all of
the Company’s impaired Non-PCD loans have been collateral-dependent, the amount of the specific reserve
historically has been determined by comparing the fair value of the collateral securing the Non-PCD loan with the
recorded investment in such loan. In the future, the Company will continue to analyze impaired Non-PCD loans on a
loan-by-loan basis and may use an alternative measurement method to determine the specific reserve, as appropriate
and in accordance with applicable accounting standards.

119

PCD loans are monitored individually or on a pooled basis quarterly to assess for changes in expected cash
flows subsequent to acquisition. If a deterioration in cash flows is identified, an increase to the PCD reserves for that
individual loan or pool of loans is made. PCD loans were recorded at their acquisition date fair values, which were
based on expected cash flows and considers estimates of expected future credit losses. The Company’s estimates of
loan fair values at the acquisition date may be adjusted for a period of up to one year as the Company continues to
evaluate its estimate of expected future cash flows at the acquisition date. If the Company determines that losses arose
after the acquisition date, the additional losses will be reflected as a provision for credit losses.

The allowance for credit losses on loans as of December 31, 2023 totaled $332.4 million or 1.57% of total loans,
including acquired loans with discounts, an increase of $50.8 million or 18.0% compared to the allowance for credit
losses on loans totaling $281.6 million or 1.49% of total loans, including acquired loans with discounts, for
December 31, 2022.

There was a $18.5 million provision for credit losses for the year ended December 31, 2023 compared to no
provision for credit losses for year ended December 31, 2022. The $18.5 million provision was made as a result of the
loans acquired in the Merger and included a $12.0 million provision for credit losses on loans and a $6.5 million
provision for credit losses on off-balance sheet credit exposures.

Net charge-offs were $38.0 million for the year ended December 31, 2023. Net charge-offs for the year ended
December 31, 2023 included $16.6 million related to resolved PCD loans and $15.0 million related to one commercial
real estate loan acquired in a previous merger. The PCD loans had reserves of $16.3 million assigned as of the

120

acquisition date. Additionally, reserves on PCD loans increased by $76.8 million due to the Merger and $23.5 million
of reserves on resolved PCD loans was released to the general reserve.

Allowance for Credit Losses on Off-Balance Sheet Credit Exposures. The allowance for credit losses on off-
balance sheet credit exposures estimates expected credit losses over the contractual period in which there is exposure
to credit risk via a contractual obligation to extend credit, except when an obligation is unconditionally cancellable by
the Company. The allowance is adjusted by provisions for credit losses charged to earnings that increase the allowance,
or by provision releases returned to earnings that decrease the allowance. The estimate includes consideration of the
likelihood that funding will occur and an estimate of expected credit losses on the commitments expected to fund. The
estimate of commitments expected to fund is affected by historical analysis of utilization rates. The expected credit
loss rates applied to the commitments expected to fund are affected by the general valuation allowance utilized for
outstanding balances with the same underlying assumptions and drivers. As of December 31, 2023 and 2022, the
Company had $36.5 million and $29.9 million, respectively, in allowance for credit losses on off-balance sheet credit
exposures; with the increase due to the Merger. The allowance for credit losses on off-balance sheet credit exposures
is a separate line item on the Company’s consolidated balance sheet. As of December 31, 2023, the Company had
$2.34 billion in commitments expected to fund.

The following table represents a rollforward of the allowance for credit losses on off-balance sheet credit

exposures for the periods shown.

Loan Modifications Made to Borrowers Experiencing Financial Difficulty. On January 1, 2023, the Company
adopted ASU 2022-02, “Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings. and
Vintage Disclosures”, which eliminated the accounting guidance for troubled debt restructurings and enhanced
disclosures for certain loan refinancing and restructurings to borrowers experiencing financial difficulty. This
guidance was applied on a prospective basis. As of the adoption date, all restructurings, including restructurings for
borrowers experiencing financial difficulty, are evaluated to determine whether they result in a new loan or a
continuation of an existing loan. Upon adoption of this guidance, the Company only establishes a specific reserve for
modifications to borrowers experiencing financial difficulty when the loan is identified as impaired. The effect of
most modifications of loans made to borrowers who are experiencing financial difficulty is already included in the
allowance for credit losses because of the measurement methodologies used to estimate the allowance. The Company
adjusts the terms of loans for certain borrowers when it believes such changes will help its customers manage their
loan obligations and increase the collectability of the loans.

Modifications to borrowers experiencing financial difficulty may include but are not limited to changes in
committed loan amount, interest rate, amortization, note maturity, borrower, guarantor, collateral, forbearance,
forgiveness of principal or interest, and other actions intended to minimize economic loss and to avoid foreclosure or
repossession of collateral. The approval of modifications of loans for borrowers experiencing financial difficulty are
handled on a case-by-case basis.

The Company did not have any loans made to borrowers experiencing financial difficulty that were modified
during the year ended December 31, 2023 that subsequently defaulted and were modified in the twelve months prior
to that default. Payment default is defined as movement to nonperforming status, foreclosure or charge-off, whichever
occurs first.

At December 31, 2022, the Company had $4.6 million in outstanding troubled debt restructurings. For the year
ended December 31, 2022, the Company added two loans totaling $3.9 million as new troubled debt restructurings,
of which $3.8 million remained outstanding at December 31, 2022. The Company did not grant principal reductions
on any restructured loans at the time of modification. There were no charge-offs related to restructured loans for the
year ended December 31, 2022.

6. FAIR VALUE

The Company uses fair value measurements to record fair value adjustments to certain assets and to determine
fair value disclosures. Fair values represent the estimated price that would be received from selling an asset or paid to
transfer a liability, otherwise known as an “exit price.” Securities available for sale are recorded at fair value on a
recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on
a nonrecurring basis. These nonrecurring fair value adjustments typically involve application of lower-of-cost-or-
market accounting or write downs of individual assets. ASC Topic 820, “Fair Value Measurements and Disclosures”
establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets
for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

Fair Value Hierarchy

The Company groups financial assets and financial liabilities measured at fair value in three levels, based on
the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair
value. These levels are:

•

•

•

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Other significant observable inputs (including quoted prices in active markets for similar assets
or liabilities) or other inputs that are observable or can be corroborated by observable market data for
substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to
the fair value of the assets or liabilities.

The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that
liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a
principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that
are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are
consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in
pricing an asset or liability.

123

The fair value disclosures below represent the Company’s estimates based on relevant market information and
information about the financial instruments. Fair value estimates are based on judgments regarding current economic
conditions, risk characteristics of the various instruments, and other factors. These estimates are subjective in nature
and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision.
Changes in the above methodologies and assumptions could significantly affect the estimates.

Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not
measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for
example, when there is evidence of impairment). These instruments include other real estate owned, repossessed
assets, held to maturity debt securities, loans held for sale, and impaired loans. For the year ended December 31, 2023,

124

the Company had additions to other real estate owned of $10.8 million, of which $1.7 million were outstanding as of
December 31, 2023. For the year ended December 31, 2023, the Company had additions to impaired loans of $52.8
million, of which $30.4 million were outstanding as of December 31, 2023. The remaining financial assets and
liabilities measured at fair value on a non-recurring basis that were recorded in 2023 and remained outstanding at
December 31, 2023 were not significant.

Entities may choose to measure eligible financial instruments at fair value at specified election dates. The fair
value measurement option (1) may be applied instrument by instrument, with certain exceptions, (2) is generally
irrevocable and (3) is applied only to entire instruments and not to portions of instruments. Unrealized gains and losses
on items for which the fair value measurement option has been elected must be reported in earnings at each subsequent
reporting date. During the reported periods, the Company had no financial instruments measured at fair value under
the fair value measurement option.

The fair value estimates presented herein are based on pertinent information available to management as of the
dates indicated. Although management is not aware of any factors that would significantly affect the estimated fair
value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since
those dates and, therefore, current estimates of fair value may differ significantly from the amounts presented herein.

The following is a description of valuation methodologies used for assets and liabilities recorded at fair value,
non-financial assets and non-financial liabilities, and for estimating fair value for financial instruments not recorded
at fair value:

Loans held for sale—Loans held for sale are carried at the lower of cost or estimated fair value. Fair value for
consumer mortgages held for sale is based on commitments on hand from investors or prevailing market prices. As
such, the Company classifies loans held for sale subjected to nonrecurring fair value adjustments as Level 2.

Loans held for investment—The Company does not record loans at fair value on a recurring basis. As such,
valuation techniques discussed herein for loans are primarily for estimating fair value disclosures. The Company
refined the calculation to estimate fair value for loans held for investment to be in accordance with ASU 2016-01. The
refined discounted cash flow calculation to determine fair value considers internal and market-based information such
as prepayment risk, cost of funds and liquidity. From time to time, the Company records nonrecurring fair value
adjustments to impaired loans to reflect (1) partial write downs that are based on the observable market price or current
appraised value of the collateral, or (2) the full charge-off of the loan carrying value. Where appraisals are not
available, estimated cash flows are discounted using a rate commensurate with the credit risk associated with those
cash flows. Assumptions regarding credit risk, cash flows and discount rates are judgmentally determined using
available market information and specific borrower information.

The Company classifies the estimated fair value of loans held for investment as Level 3.

Other real estate owned—Other real estate owned is primarily foreclosed properties securing residential loans
and commercial real estate loans. Foreclosed assets are adjusted to fair value less estimated costs to sell upon transfer
of the loans to other real estate owned. Subsequently, these assets are carried at the lower of carrying value or fair
value less estimated costs to sell. Other real estate carried at fair value based on an observable market price or a current
appraised value is classified by the Company as Level 2. When management determines that the fair value of other
real estate requires additional adjustments, either as a result of a non-current appraisal or when there is no observable
market price, the Company classifies the other real estate as Level 3.

The fair value estimates presented herein are based on pertinent information available to management at
December 31, 2023. Although management is not aware of any factors that would significantly affect the estimated
fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements
since those dates and, therefore, current estimates of fair value may differ significantly from the amounts presented
herein.

Bank Term Funding Program— During the second quarter of 2023, the Bank began participating in the Federal
Reserve Board’s BTFP. Under the BTFP program, eligible depository institutions can obtain loans of up to one year
in length by pledging U.S. Treasuries, agency debt and mortgage-backed securities, and other qualifying assets as
collateral. These assets are valued at par. Eligible depository institutions can request advances under the BTFP until
at least March 11, 2024. At December 31, 2023, the Bank had secured borrowing capacity of $4.40 billion
collateralized by the par value of pledged securities totaling $4.40 billion. At December 31, 2023, the balance

127

outstanding was $3.73 billion consisting of a one term advance maturing in December 2024 with a weighted average
interest rate of 4.83%.

FHLB advances and long-term notes payable—The Company has an available line of credit with the FHLB of
Dallas, which allows the Company to borrow on a collateralized basis. The Company’s FHLB advances are typically
considered short-term borrowings and are used to manage liquidity as needed. Maturing advances are replaced by
drawing on available cash, making additional borrowings or through increased customer deposits. At December 31,
2023, the Company had total borrowing capacity of $10.85 billion under this line. At December 31, 2023, the
Company had no FHLB advances or long-term notes payable balance outstanding.

Securities sold under repurchase agreements with Company customers—At December 31, 2023, the Company
had $309.3 million in securities sold under repurchase agreements compared with $428.1 million at December 31,
2022, a decrease of $118.9 million or 27.8%, with weighted average interest rates paid of 2.42% and 0.58% for the
years ended December 31, 2023 and 2022, respectively. Repurchase agreements are generally settled on the following
business day; however, approximately $3.0 million of repurchase agreements outstanding at December 31, 2023 have
maturity dates ranging from 12 to 24 months. All securities sold under repurchase agreements are collateralized by
certain pledged securities.

Subordinated debentures— On May 1, 2023, in connection with the acquisition of First Bancshares, the
Company assumed the obligation related to $3.1 million of Floating Rate Junior Subordinated Deferrable Interest
Debentures and trust preferred securities (the "Subordinated Debentures"), which the Company redeemed on
September 18, 2023. Accordingly, as of December 31, 2023, the Company had no Subordinated Debentures
outstanding.

Net deferred tax assets

$

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during
the periods in which those temporary differences become deductible. Management considers the scheduled reversal
of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment.
Based upon the level of historical taxable income and estimates of future taxable income over the periods for which
the deferred tax assets are deductible, management believes it is more likely than not the Company will realize the
benefits of these deductible differences at December 31, 2023.

Benefits from tax positions are recognized in the financial statements only when it is more likely than not that
the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge
of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the
largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax
positions that previously failed to meet the more-likely-than-not recognition threshold are recognized in the first
subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer
meet the more-likely-than-not recognition threshold are derecognized in the first subsequent financial reporting period
in which that threshold is no longer met. The Company had no tax positions at December 31, 2023 or December 31,
2022 that did not meet the more-likely-than not recognition threshold. ASC Topic 740 “Income Taxes” also provides
guidance on the accounting for and disclosure of unrecognized tax benefits, interest and penalties. The Company’s
policy for recording interest and penalties associated with audits is to record such items as a component of income
before taxes. Penalties are recorded in other (gains) losses and interest paid or received is recorded in interest expense
or interest income, respectively, in the consolidated statement of income. As of December 31, 2023 and 2022, the
Company has not accrued any interest and penalties related to unrecognized tax benefits. The Company has identified
its federal tax return and its state tax returns in Texas, Oklahoma, Colorado, New Mexico and New York as “major”
tax jurisdictions, as defined. The Bank has identified its state returns in Arkansas, Florida, Georgia, Idaho, North
Carolina, Pennsylvania, Tennessee and Washington as “major” tax jurisdictions, as defined. The periods subject to
examination for the Company’s federal return are the 2020 through 2023 tax years. The Company has assumed net
operating loss carryforwards, “acquired NOLs”, through its previous acquisitions. The tax periods of the acquired
entities from which these acquired NOLs originated are considered open years for purposes of adjusting the amount

129

of the acquired NOLs used in the Company’s open years. As of December 31, 2023, the Company has fully utilized
all acquired NOLs.

11. STOCK INCENTIVE PROGRAMS

At December 31, 2023, Bancshares had one active stock-based incentive compensation plan with awards
outstanding. The Company accounts for stock-based incentive compensation plans using the fair value-based method
of accounting. The Company recognized stock-based compensation expense of $12.2 million, $11.8 million and $12.6
million for the years ended December 31, 2023, 2022 and 2021, respectively. There was approximately $1.7 million,
$1.5 million and $1.4 million of income tax benefit recorded for the stock-based compensation expense for the same
periods, respectively.

On March 3, 2020, Bancshares’ Board of Directors established the Prosperity Bancshares, Inc. 2020 Stock
Incentive Plan (the “2020 Plan”), which was approved by the Bancshares’ shareholders at the annual meeting of
shareholders on April 21, 2020. The 2020 Plan authorizes the issuance of up to 2,500,000 shares of common stock
upon the exercise of options or pursuant to the grant or exercise, as the case may be, of other awards granted under
the 2020 Plan, including incentive stock options, nonqualified stock options, stock appreciation rights, shares of
restricted stock and restricted stock units. As of December 31, 2023, 65,932 shares of restricted common stock have
vested and 510,522 shares of unvested restricted stock have been issued under the 2020 Plan.

Restricted Stock

During 2023, 2022 and 2021, Bancshares granted shares of restricted stock pursuant to the 2020 Plan. These
shares of restricted stock generally vest over a period of one to three years. The Company accounts for restricted stock
grants by recording the fair value of the grant as compensation expense over the vesting period. Compensation expense
related to restricted stock was $12.2 million, $11.8 million and $12.6 million for the years ended December 31, 2023,
2022 and 2021, respectively.

A summary of the status of nonvested shares of restricted stock as of December 31, 2023, and changes during

the year then ended is as follows:

As of December 31, 2023, there was $7.1 million of total unrecognized compensation expense related to stock-
based compensation arrangements. That cost is expected to be recognized over a weighted average period of 1.43
years.

13. PROFIT SHARING PLAN

The Company has adopted a profit sharing plan pursuant to Section 401(k) of the Internal Revenue Code (the
“Code”), whereby the participants may contribute a percentage of their compensation as permitted under the Code.
Matching contributions are made at the discretion of the Company. Presently, the Company matches 50% of an
employee’s contributions, up to 15% of such employee’s compensation, not to exceed the maximum allowable
pursuant to the Code and excluding catch-up contributions. Such matching contributions were approximately $6.0
million, $6.4 million and $7.2 million for the years ended December 31, 2023, 2022 and 2021, respectively.

14. OFF-BALANCE SHEET ARRANGEMENTS, COMMITMENTS AND CONTINGENCIES

The Company’s contractual obligations and other commitments to make future payments (other than deposit

obligations and securities sold under repurchase agreements) as of December 31, 2023 are summarized below.

Contractual Obligations

The Company’s future cash payments associated with its contractual obligations pursuant to its Federal Reserve
Board’s BTFP as of December 31, 2023 is summarized below. The future interest payments were calculated using
the current rate in effect at December 31, 2023. Payments under the BTFP include interest of $173.9 million that will
be due over the future periods. These payments do not include prepayment options that may be available to the
Company.

Off-Balance Sheet Items

In the normal course of business, the Company enters into various transactions that, in accordance with GAAP,
are not included in its consolidated balance sheets. The Company enters into these transactions to meet the financing
needs of its customers. These transactions include commitments to extend credit and standby letters of credit, which
involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the
consolidated balance sheets.

The Company’s commitments associated with outstanding standby letters of credit, unused capacity on
Warehouse Purchase Program loans and commitments to extend credit expiring by period as of December 31, 2023
are summarized below. Since commitments associated with letters of credit, unused capacity of Warehouse Purchase
Program loans and commitments to extend credit may expire unused, the amounts shown may not necessarily reflect
the actual future cash funding requirements.

Standby Letters of Credit. Standby letters of credit are written conditional commitments issued by the Company
to guarantee the payment by or performance of a customer to a third party. If the customer does not perform in
accordance with the terms of the agreement with the third party, the Company would be required to fund the
commitment. The maximum potential amount of future payments the Company could be required to make is
represented by the contractual amount of the commitment. If the commitment is funded, the Company would be
entitled to seek recovery from the customer. The Company’s policies generally require that standby letter of credit
arrangements contain security and debt covenants similar to those contained in loan agreements.

Unused Capacity on Warehouse Purchase Program Loans. For Warehouse Purchase Program loans, the
Company has established maximum purchase facility amounts, but reserves the right, at any time, to refuse to buy any
mortgage loans offered for sale by each customer, for any reason.

Commitments to Extend Credit. The Company enters into contractual commitments to extend credit, normally
with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of the
Company’s commitments to extend credit are contingent upon customers maintaining specific credit standards at the
time of loan funding. The Company minimizes its exposure to loss under these commitments by subjecting them to
credit approval and monitoring procedures. Management assesses the credit risk associated with certain commitments
to extend credit in determining the level of the allowance for credit losses.

At December 31, 2023, $381.5 million of commitments to extend credit and standby letters of credit have fixed

rates ranging from 0% to 21.0%.

The Company evaluates customer creditworthiness on a case-by-case basis. The amount of collateral obtained,
if considered necessary by the Company upon extension of credit, is based on management’s credit evaluation of the
customer.

Allowance for Credit Losses on Off-Balance Sheet Credit Exposures. The Company records an allowance for
credit losses on off-balance sheet credit exposure that is adjusted through a charge to provision for credit losses on
the Company’s consolidated statement of income. At December 31, 2023 and 2022, this allowance, reported as a
separate line item on the Company’s consolidated balance sheet, totaled $36.5 million and $29.9 million, respectively.
The increase in the allowance was primarily due to the Merger.

132

Leases

The Company’s leases relate primarily to operating leases for office space and banking centers. The Company
determines if an arrangement is a lease or contains a lease at inception. The Company’s leases have remaining lease
terms of 1 to 15 years, which may include the option to extend the lease when it is reasonably certain for the Company
to exercise that option. Operating lease right-of-use (“ROU”) assets and liabilities are recognized at
the
commencement date based on the present value of lease payments over the lease term. The Company uses its
incremental collateralized borrowing rate to determine the present value of lease payments. Short-term leases and
leases with variable lease costs are immaterial and the Company has one sublease arrangement. Sublease income for
the years ended December 31, 2023, 2022 and 2021 was $3.1 million, $3.2 million and $3.1 million, respectively. As
of December 31, 2023, operating lease ROU assets and lease liabilities were approximately $36.8 million. ROU assets
and lease liabilities were classified as other assets and other liabilities, respectively.

As of December 31, 2023, the weighted average remaining lease terms of the Company’s operating leases were
5.1 years. The weighted average discount rate used to determine the lease liabilities as of December 31, 2023 for the
Company’s operating leases was 2.7%. Cash paid for the Company’s operating leases for the years ended December
31, 2023, 2022 and 2021 was $12.0 million, $10.9 million and $12.2 million, respectively. During the year ended
December 31, 2023, the Company obtained $3.6 million in ROU assets in exchange for lease liabilities for eight
operating leases, four of which, reflecting $2.7 million in ROU assets, were related to the Merger.

The Company’s future undiscounted cash payments associated with its operating leases as of December 31,

2023 are summarized below (dollars in thousands).

It is expected that in the normal course of business, expiring leases will be renewed or replaced by leases on

other property or equipment.

Rent expense under all operating lease obligations aggregated approximately $12.1 million, $10.9 million, and

$11.6 million for the years ended December 31, 2023, 2022 and 2021, respectively.

Litigation—The Company and the Bank are defendants, from time to time, in legal actions arising from
transactions conducted in the ordinary course of business. After consultations with legal counsel, the Company and
the Bank believe that the ultimate liability, if any, arising from such actions will not have a material adverse effect on
their financial statements.

These financial instruments are not designated as hedging instruments and are used for asset and liability
management and commercial customers’ financing needs. All derivatives are carried at fair value in either other assets
or other liabilities and all related cash flows are reported in the operating section of the consolidated statements of
cash flows.

Interest rate lock commitments (“IRLCs”) — In the normal course of business, the Company enters into interest
rate lock commitments with consumers to originate mortgage loans at a specified interest rate. These commitments,
which contain fixed expiration dates, offer the borrower an interest rate guarantee provided the loan meets
underwriting guidelines and closes within the timeframe established by the Company.

Forward mortgage-backed securities trades — The Company manages the changes in fair value associated with
changes in interest rates related to IRLCs by using forward sold commitments known as forward mortgage-backed
securities trades. These instruments are typically entered into at the time the interest rate lock commitment is made.

Interest rate swaps and caps — These derivative positions relate to transactions in which the Company enters
into an interest rate swap or cap with a customer, while at the same time entering into an offsetting interest rate swap
or cap with another financial institution. An interest rate swap transaction allows the Company’s customer to
effectively convert a variable rate loan to a fixed rate. In connection with each swap, the Company agrees to pay
interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a
similar notional amount at a fixed interest rate. At the same time, the Company agrees to pay another financial
institution a similar fixed interest rate on the same notional amount and receive substantially the same variable interest
rate on the same notional amount. In connection with each interest rate cap, the Company sells a cap to the customer
and agree to pay interest if the underlying index exceeds the strike price defined in the cap agreement. Simultaneously
the Company purchases a cap with matching terms from another financial institution that agrees to pay the Company
if the underlying index exceeds the strike price.

The commercial loan customer counterparty weighted average received and paid interest rates for interest rate

swaps outstanding at December 31, 2023 and 2022 are presented in the following table.

The Company’s credit exposure on interest rate swaps is limited to the net favorable value of all swaps by each
counterparty, which was approximately $3.9 million and $5.5 million at December 31, 2023 and 2022, respectively.
This credit exposure is partly mitigated as transactions with customers are secured by the collateral, if any, securing
the underlying transaction being hedged. The Company’s credit exposure, net of collateral pledged, relating to interest
rate swaps with upstream financial institution counter-parties was zero at December 31, 2023. A credit support annex
is in place and allows the Company to call collateral from upstream financial institution counter-parties. Collateral
levels are monitored and adjusted on a regular basis for changes in interest rate swap values. The Company’s cash
collateral pledged for interest rate swaps was zero at December 31, 2023 and 2022, respectively.

The initial and subsequent changes in the fair value of IRLCs and the forward sales of mortgage-backed
securities are recorded in net gain on sale of mortgage loans. These gains and losses were not attributable to
instrument-specific credit risk. For interest rate swaps and caps, because the Company acts as an intermediary for its
customer, changes in the fair value of the underlying derivative contracts substantially offset each other and do not
have a material impact on its results of operations. Income for the years ended December 31, 2023, 2022 and 2021

17. REGULATORY MATTERS

Bancshares and the Bank are subject to various regulatory capital requirements administered by the federal
banking agencies. Any institution that fails to meet its minimum capital requirements is subject to actions by regulators
that could have a direct material effect on its financial statements. Under the capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines based on the Bank’s
assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. Bancshares’
and the Bank’s capital amounts and the Bank’s classification under the regulatory framework for prompt corrective
action are also subject to qualitative judgments by the regulators about the components, risk weightings and other
factors.

The Basel III Capital Rules adopted by the federal regulatory authorities in 2013 substantially revised the risk-
based capital requirements applicable to Bancshares and the Bank. The Basel III Capital Rules became effective for
Bancshares and the Bank on January 1, 2015, subject to a phase-in period for certain provisions. Among other things,
the Basel III Capital Rules introduced a new capital measure called “Common Equity Tier 1” (“CET1”), which is a
comparison of the sum of certain equity capital components to total risk-weighted assets, and revised the risk-
weighting approach of the capital ratios with a more risk-sensitive approach that expanded the risk-weighting
categories from the previous Basel I derived categories to a much larger and more risk-sensitive number of categories,
depending on the nature of the assets.

In response to the COVID-19 pandemic, in March 2020 the joint federal bank regulatory agencies issued an
interim final rule that allowed banking organizations that implemented CECL in 2020 to mitigate the effects of the
CECL accounting standard in their regulatory capital for two years. This two-year delay is in addition to the three-
year transition period that the agencies had already made available. The Company adopted the option provided by the
interim final rule, which delayed the effects of CECL on its regulatory capital through 2021, after which the effects
will be phased in over a three-year period from January 1, 2022 through December 31, 2024. Under the interim final
rule, the amount of adjustments to regulatory capital deferred until the phase-in period include both the initial impact
of the Company’s adoption of CECL on January 1, 2020 and 25% of subsequent changes in the Company’s allowance
for credit losses during each quarter of the two-year period ending December 31, 2021. The cumulative amount of the
transition adjustments is being phased in over the three-year transition period that began on January 1, 2022, with 75%
recognized in 2022, 50% recognized in 2023, and 25% recognized in 2024.

To meet the capital adequacy requirements, Bancshares and the Bank must maintain minimum capital amounts
and ratios of CET1, Tier 1 and Total capital to risk weighted assets, and of Tier 1 capital to adjusted quarterly average
assets as defined in the regulations. As of December 31, 2023, Bancshares and the Bank met all capital adequacy
requirements to which they were subject.

Since being fully phased in on January 1, 2019, the Basel III Capital Rules require Bancshares and the Bank to
maintain a capital conservation buffer, composed entirely of CET1, of 2.5%, effectively resulting in minimum ratios
of (1) CET1 to risk-weighted assets of 7.0%, (2) Tier 1 capital to risk-weighted assets of 8.5%, (3) total capital (that
is, Tier 1 plus Tier 2) to risk-weighted assets of 10.5% and (4) Tier 1 capital to average quarterly assets as reported on
consolidated financial statements ( known as the “leverage ratio”) of 4.0%.

The CET1, Tier 1 and total capital ratios are calculated by dividing the respective capital amounts by risk
weighted assets. Risk weighted assets include total assets, excluding goodwill and other intangible assets, allocated
by risk weight category, and certain off-balance-sheet items. The leverage ratio is calculated by dividing Tier 1 capital
by adjusted quarterly average total assets, excluding goodwill and other intangible assets.

As of December 31, 2023, the most recent notification from the FDIC categorized the Bank as “well capitalized”
under the regulatory framework for prompt corrective action. There have been no conditions or events since that
notification which management believes have changed the Bank’s category. To be categorized as well capitalized the
Bank must maintain minimum CET1 risk-based, Tier 1 risk-based, total risk-based and Tier 1 leverage ratios as set
forth in the table below.
